Sandhog Tools is the export brand of the Chinese plant Ningbo Sanhan Alloy Materials Co., Ltd. (宁波三韩合金材料有限公司), founded in 2004. The production site is in Cixi, Ningbo, Zhejiang province: 333 Liantang Road, Cidong Binhai Development Zone, Longshan Town, Cixi 315311. Its own insert brand is SUPERMETALLOY, and a second official website of the same legal entity is www.sandhogtool.com.
We work with this brand primarily on tooling and cutting tools: turning and boring holders, grooving and threading holders, milling cutters, U-drill bodies and solid carbide tools. Replaceable inserts and holder spare parts — shims, screws, pins and wrenches — come as an addition: they are consumed in operation but are selected for a specific body, so it helps to state both the holder and the insert in a request.
What the manufacturer's official pages confirm: holders have a forged 42CrMo body with heat treatment and clamping types A(D), P, S, B, M and W; grooving holders are spring steel or 42CrMo with chemical plating or a black coating; threading holders use a holder plus shim plus screws design; face milling cutters have a body diameter of 40–315 mm in 10 sizes, with a 90° cutter of 40–250 mm for ANKX inserts; U-drills offer 2D and 3D depth, 12.5–45 mm diameter and two coolant channels; the body series designation is confirmed for the specific item against the manufacturer's documentation.
What remains unconfirmed and is therefore not claimed: the manufacturer publishes no complete spare parts catalogue with sizes or compatibility tables; the one published technical block covers grooving inserts only and applies to the group as a whole; there is no detail at all on end mills or milling tool holders; two catalogue sections, Clamp and Carbide end mill, contain no products. Specifications for specific series and items are confirmed against the manufacturer's documentation during selection. Warranty, prices, lead times and payment terms are not disclosed on the official pages, no EAEU or TR TS certificates were found in the sources verified, and the manufacturer declares no official dealers or representations in Russia and the CIS. The Russian version at ru.sandhogtools.com is a machine translation of the same website.
Choose a Sandhog Tools line
Below are eight lines of tooling and cutting tools and six groups of consumables and spare parts. Where information is confirmed by an official manufacturer page it is stated directly; where the manufacturer discloses no specifications this is said as well, and such items are not presented as confirmed. Technical data is published for grooving inserts only and applies to the group as a whole rather than to a single designation.
Sandhog turning tool holders
Sandhog turning tool holders are the core tooling of the brand. The manufacturer states the body as forged 42CrMo with heat treatment, claims wear resistance, strength and rigidity, and lists the insert clamping types as A(D), P, S, B, M and W. Confirmed models: MTJNR2525M16, ACKNR2525M12, PCLNR, MVJNR2525M16, BVJNR2525M16, WTENN2525M22, MSBNR3232P12 and S08K-SCLCR06. The holder itself is not a consumable: the insert, shim and screw are replaced, while the body serves for years unless the insert seat is damaged.
Selection needs the shank cross-section, the insert clamping type and the operation: external or internal turning, parting off, face machining. It helps to state the insert designation that should sit in the holder and the workpiece material, because the insert-plus-shim-and-screw set depends on them. If the holder is already on site, its designation and a photograph of the insert seat are enough.
Sandhog boring bars come in two versions: solid carbide and 42CrMo. The manufacturer attributes vibration resistance and damping to the carbide version and positions it for small and deep holes where a standard bar lacks rigidity. Confirmed models: S20QMSKNR12, MDJNR2020K1504, SVQBR1616H11 and S08K-SCLCR06. Micro boring is a separate line: low cutting force, stability and accuracy are claimed, and the application is placed in automotive and aircraft engines and precision instruments.
Selection needs the hole diameter and depth, the workpiece material, the machine and the required accuracy. For deep or small-diameter holes, state separately whether through-tool coolant supply is available and at what pressure, because this directly affects the small-diameter range. Also give the insert designation if a replaceable insert is used, or the bar designation if the bar is already on site.
Sandhog grooving tool holders are described by the manufacturer as a solid forging in spring steel or 42CrMo, heat-treated after forging and finished with chemical plating or a black coating. They cover straight, circular, deep, shallow, internal and external face grooving. Confirmed models: MGEHR, TTER2020, TTER, TGF32R, JSTGR, JSTGR2020 and MGFVR325. Rigidity matters most in this group, because grooving applies a side load to the insert.
Selection needs the groove width and depth, whether it is external or internal, the part diameter, the material and the machine. State separately any requirement for the groove bottom radius and the surface finish: shallow and face grooving call for one holder type, deep grooving for another. It helps to give the insert designation that is to run in the holder.
Sandhog threading tool holders are made for internal and external threads, with machine clamping and a body cut entirely from 42CrMo forgings. The manufacturer describes the design as holder plus shim plus screws, and the shim here is a working part rather than an accessory: it sets the insert angle and height. The insert finish is matched to the material: uncoated for non-ferrous metals including aluminium and copper alloys, coated for steel, cast iron, stainless steel and alloys. Confirmed models: B-SER2020, SER2525, SER2020K16 and SNR0016Q16.
Selection needs the thread type (metric, American, British), the pitch, whether it is external or internal, the part diameter and the material. Always state the thread direction and any limit on the threaded length if it runs into a shoulder or the bottom of a hole. When replacing only an insert, a photograph of the shim helps: on threading holders a lost or worn shim immediately shifts the thread profile.
Sandhog U-drill bodies are made for SOMT, SPMT and WCMT replaceable inserts. The manufacturer states 2D and 3D drilling depth, a diameter range of 12.5–45 mm, a heat-treated body and two coolant channels. A separate page covers two body models for WCMT inserts. The body series designation is confirmed for the specific item against the manufacturer's documentation.
Selection needs the hole diameter and depth, the body series and designation, the insert type (SOMT, SPMT or WCMT), the machine shank and the available coolant pressure. For deep holes, chip evacuation is checked separately: at 3D depth coolant supply requirements are higher. The peripheral and central inserts differ, so it is better to list them separately.
Sandhog face milling cutters are described by the manufacturer as double-sided helical designs: body diameter 40–315 mm in 10 sizes, with square double-sided inserts of 8 cutting edges and octagonal inserts of 16. This is body tooling: the cutter itself serves a long time while the inserts and fasteners are consumed. The number of pockets determines how many inserts a set needs and how the load is distributed over the body.
Selection needs the cutter diameter and number of pockets, the body or insert designation, the workpiece material, the operation (roughing or finishing) and the machine: the arbor and shank must match the spindle. If the cutter is already on site, a photograph of the body and the designation of the insert that ran in it are enough.
The manufacturer describes a separate 90° cutter for shoulder machining: diameter 40–250 mm and the ANKX insert series as the working insert. This cutter produces a square corner between the face and the shoulder wall, so it is used where a clean vertical shoulder is required rather than the radius left by a standard face mill. Body and ANKX inserts are stated as linked: the insert is selected for the specific body, not the other way round.
Selection needs the shoulder height and depth, the cutter diameter, the machine and the workpiece material. State whether a true square corner is required and what surface finish the shoulder wall needs: inserts for semi-finishing and finishing passes are selected separately. It also helps to say whether the machine supplies through-tool coolant via the arbor.
The solid group, as the manufacturer defines it, includes a carbide drill with internal coolant supply and a wear-resistant coating stated for stainless and alloy steel, a thread end mill for thread milling instead of tapping, micro boring tools and a crown diamond drill. These are not consumables but tooling: the tool either works or is replaced as a whole. For every item listed the manufacturer discloses neither models nor sizes, so we describe them by purpose and do not quote designations that do not appear on the official pages.
Selection needs the workpiece material, the machining diameter and depth, the machine and the required accuracy; for thread milling, the thread type and pitch. Because the manufacturer publishes no models or sizes, the item is confirmed by purpose and by the specific operation, with the designation confirmed separately. For drilling, state the coolant pressure and supply method.
Sandhog turning inserts are carbide replaceable inserts with a PVD coating and a chipbreaker; the manufacturer positions them for semi-finishing and finishing of carbon and alloy steel, stainless steel and heat-resistant alloys. Confirmed designations: VNMG1604, VNMG16, TNMG1604, WNMG0804, WNMG080408, TCMT11, DCMT11, DCGT11, DCGT11T304, CCGT and DNMG15. The DCGT11 version is described separately for aluminium and non-ferrous metals. The designations CNMG and SNMG do not appear on the official pages.
Selection needs the insert shape and geometry, the nose radius, the chipbreaker class, the coating, the workpiece material and the operation. The holder the insert goes into must be stated: the clamping type governs both the insert and the shim-and-screw set. If the designation has worn off, a top-view photograph of the insert with its size helps.
Sandhog threading inserts are offered in ground and pressed versions, and the manufacturer separately notes full grinding along the tooth edge. Metric, American and British threads are covered. Confirmed designations: 16ER/IR2.0TR, 16ER/IR2.0ISO, 16ER1.5ISO, 16ER/IR1.5ISO, 16ERAG60 and 16ER/IRAG60 in grade SH945, plus 16ER/IR10RD to DIN 405 with a 10 TPI pitch and a red coating. Grade SH945 is described by the manufacturer as universal for steel, stainless steel and cast iron, with a TiN-coated version stated as available.
Selection needs the thread profile and pitch, the direction (external or internal), the workpiece material and the holder designation. State whether a ground or a pressed insert is required, as this affects profile accuracy and the cost of the item. For non-standard profiles, a thread drawing with the tolerance is helpful.
Sandhog grooving inserts are triangular and double-sided, carbide, fully ground and coated with CVD or PVD; the manufacturer states their purpose as shallow grooves, internal grooves, O-ring grooves and hydraulic fitting grooves. Confirmed designations: GBA43, MGMN, MGMN300-DR, PENTA24N300PF020, TDJ300, TDXU and TDC5. This is the only group for which the manufacturer publishes a technical block: WC-Co base, 6–10 % cobalt, 0.8–2.0 µm grain, optional TiAlN coating, thickness tolerance ±0.01 mm, cutting edge radius 0.02–0.05 mm, mounting hole tolerance ±0.02 mm, working temperature up to 800 °C coated and 600 °C uncoated, cutting speed 80–300 m/min, hardness 90–92 HRA. These are manufacturer-published figures for the group as a whole, not for a specific designation.
Selection needs the groove width and depth, the bottom radius, whether it is external or internal, the part diameter and the material. If the groove is for a sealing ring or a fitting, state the standard or attach a drawing: the manufacturer places O-ring grooves and fitting grooves in different versions. Technical data is published for the group as a whole, so figures for a specific designation are confirmed separately.
Sandhog milling inserts are described by the manufacturer as multilayer PVD-coated and are placed in the submicron grain class. Confirmed series: ONMU, SNMU, ANKX, APMT, APKT, 3PKT, LOGU, LNMU, R390 and BLMP. The ANKX inserts are linked by the manufacturer to the 90° shoulder cutter, while square and octagonal double-sided inserts go with bodies of 40–315 mm diameter and 8 and 16 cutting edges respectively. A milling insert wears faster than a turning insert because of interrupted cutting, so a set for a body is usually ordered with spare capacity per pocket.
Selection needs the insert designation, the body diameter and number of pockets, the workpiece material and the operation. The fastener is confirmed separately: the screw for a specific insert is often ordered on its own because it is lost or stripped during a change. If the designation has worn off, a photograph of the insert and of the body pocket helps.
Sandhog U-drill inserts are divided by the manufacturer by body type and by insert. Confirmed designations: WCMT050308, WCMT06T308, SPMG090408 and SPMG09. The bodies are the SDA and MDR series for SOMT, SPMT and WCMT inserts, with 2D and 3D drilling depth, a diameter of 12.5–45 mm and two coolant channels. A separate page covers two body models for WCMT inserts. The life of a U-drill insert depends heavily on coolant supply: at insufficient pressure the edge burns out noticeably faster.
Selection needs the insert designation, the body series and diameter, the drilling depth (2D or 3D), the material and the machine coolant pressure. Central and peripheral inserts differ, so they are listed separately and with quantities. When ordering a set for a body it makes sense to include the screws for these inserts.
The Spare parts section on the manufacturer's website lists the holder part types. Confirmed: Shim with 3 items including the carbide shim MC1204; Screw with 3 items (double-head screw, hex socket screw for an Allen key, and a Torx screw); Pin with 1 item, a pin for tool holders; Wrench with 2 items, a Torx T8/T15 key and an internal hex key. The Clamp section is declared in the catalogue but contains no products. The manufacturer describes the clamping arrangement as holder plus shim plus insert, with the shim held by screws. Specific sizes and designations are confirmed against the manufacturer's documentation during selection.
Selection needs the holder designation, a photograph of the worn part and, if it survives, the shim designation such as MC1204. The manufacturer publishes no complete spare parts catalogue with sizes and compatibility tables: the pages list part types and single items, so the specific size is confirmed for the holder. For screws it helps to give the head type and length.
On the Download page the manufacturer lists five catalogues: Automatic holders, Cutting tool holder, Carbide insert, Drilling tool and Carbide tool, covering automatic holders, cutting tool holders, carbide inserts, drilling tools and carbide tools, all updated on 17 January 2025. The Product Category section contains 29 sections. What the official pages do not disclose: CE, ISO, EAEU and TR TS certificates, warranty terms and duration, prices, lead times and payment terms; no certificate of origin is published as an official declaration; no official dealers or representations in Russia and the CIS are declared. Specifications for specific series and items are confirmed against the manufacturer's documentation during selection.
For selection this means a simple sequence: first the holder designation and a photograph of the worn part, then a check against the manufacturer's published group descriptions, then confirmation of the shim size, screw type and specifications against the manufacturer's documentation for the specific item.
Describe the operation and the material: external or internal turning, boring, parting and grooving, threading, face and shoulder milling, drilling. The material drives the choice of version — the manufacturer names steel, alloy and stainless steel, cast iron, aluminium, copper and copper alloys, heat-resistant alloys and composites. State the machine, the tool holding method and the available coolant pressure: for U-drills and solid carbide drills with internal coolant supply this is a defining figure, not a secondary one. For holders you will need the shank cross-section, the clamping type and the insert designation; for cutters the diameter, the number of pockets and the required surface finish; for inserts the shape, nose radius and chipbreaker class. If the item is already in production, its designation and a photograph of the insert seat are enough.
Inserts, holder spare parts and what is not disclosed
Sandhog replaceable inserts fall into four groups: turning (confirmed VNMG1604, VNMG16, TNMG1604, WNMG0804, WNMG080408, TCMT11, DCMT11, DCGT11, DCGT11T304, CCGT, DNMG15, PVD coated with a chipbreaker), threading (16ER/IR2.0TR, 16ER/IR2.0ISO, 16ER1.5ISO, 16ER/IR1.5ISO, 16ERAG60, 16ER/IRAG60 in grade SH945, 16ER/IR10RD to DIN 405), grooving (GBA43, MGMN, MGMN300-DR, PENTA24N300PF020, TDJ300, TDXU, TDC5) and milling (ONMU, SNMU, ANKX, APMT, APKT, 3PKT, LOGU, LNMU, R390, BLMP series), plus U-drill inserts (WCMT050308, WCMT06T308, SPMG090408, SPMG09). Holder spare parts are shims (3 items including the carbide MC1204), screws (3 items: double-head, Allen socket, Torx), a pin (1 item) and wrenches (Torx T8/T15 and hex). The Clamp section is declared in the catalogue but contains no products, so we do not present it as an assortment. Specifications for specific series and items are confirmed against the manufacturer's documentation during selection. The designations CNMG and SNMG do not appear on the official pages and are not quoted as Sandhog models.
Send the operation, the material and the machine
State what is required: tooling for an operation, replaceable inserts, holder spare parts or solid carbide tools, and add the destination city and the quantity. If the item is a consumable for existing equipment, help with the holder designation and photographs of the worn part. We will state what is officially confirmed and what needs separate checking: the manufacturer has no complete spare parts catalogue with sizes or compatibility tables, no detail is disclosed on end mills or milling tool holders, warranty, prices and lead times are not published, no EAEU or TR TS certificates were found in the sources verified, and no official dealers or representations in Russia and the CIS are declared.
