Equipment and spare partsBrowse manufacturers Search by manufacturerDirect engineering supply and worldwide technical support for precision CNC tool holding systems and machine tooling engineered by Dezhou Bright Machinery Co., Ltd. (Bright Tools) for turning, milling, and 5-axis machining centers. We engineer, customize, and deliver precision MAS 403 BT tapers, dual-contact HSK DIN 69893 holders, DIN 69871 SK holders, ER8–ER50 collets, modular boring systems NBH/RBH, static VDI blocks, and heavy-duty BMT45–BMT85 live tooling.
Bright Tools MAS 403 BT taper holders (BT30, BT40, BT50) are precision-manufactured from premium 20CrMnTi alloy steel, case-hardened to HRC 58-62 with a case depth exceeding 0.8 mm. Taper accuracy conforming to ISO AT3 ensures over 85% spindle contact area, effectively eliminating vibration and runout under high-speed milling loads. The product line includes high-accuracy ER collet chucks (ER11 through ER40) with runout within 0.003-0.005 mm, high-torque SC power milling chucks for heavy metal removal, PHC hydraulic chucks for fine finishing, shrink-fit holders for ultra-rigid high-RPM tooling, FMB face mill arbors, and tension-compression tapping chucks. All tool holders are dynamically balanced to G2.5 at 20,000 to 25,000 RPM to safeguard machine spindle life.
Bright Tools HSK tool holding systems (DIN 69893 / ISO 12164) are engineered for high-speed machining (HSM) and demanding multi-axis milling operations. Utilizing a short 1:10 hollow taper combined with simultaneous face and taper contact under drawbar clamping force, HSK tooling provides superior radial stiffness, axial repeatability, and dynamic balance stability under centrifugal forces. The range covers HSK-A50, HSK-A63, and HSK-A100 for general and heavy-duty milling, symmetrically balanced keyless HSK-E32, HSK-E40, and HSK-E50 for high-RPM mold finishing up to 40,000 RPM, and HSK-F63 for high-speed aluminum and non-ferrous routing. Available in ER collet, hydraulic, shrink-fit, and shell mill configurations with central coolant tubes.
Bright Tools DIN 69871 (SK, DAT, ISO 7388-1) and ANSI B5.50 (CAT40, CAT50) tool holders are designed for high-performance milling, drilling, and boring operations across European and American CNC machining centers (such as DMG MORI, Haas, Mazak, Hermle, and Hurco). Manufactured from high-tensile alloy case-hardening steel, all tapers and tool changer drive slots are precision ground. The product portfolio includes ER collet chucks (ER16 through ER40), heavy OZ collet chucks (OZ25, OZ32 DIN 6388), integrated one-piece keyless drill chucks APU (SK40-APU08, APU13, APU16), hydraulic tool holders, FMB face mill arbors, Morse taper holders (MTA tang type and MTB drawbar type), and Weldon side-lock holders (DIN 1835-B / DIN 6359) for solid carbide and HSS end mills.
Bright Tools precision collets are crafted from select 65Mn / SUJ2 spring steel, subjected to cryogenic stress relief and sub-micron multi-axis grinding. The standard ER range (DIN 6499 / ISO 15488) spans from compact ER8 and ER11 up to heavy-duty ER20, ER25, ER32, ER40, and ER50 in 0.5 mm and 1.0 mm clamping steps. Accuracy tiers include standard grade (0.015 mm runout), precision grade A (0.008 mm runout), and ultra-precision UP/HP grade (runout < 0.005 mm at 3xD). For through-tool high-pressure coolant machining up to 70–100 bar, sealed ERS (ER-C) collets prevent fluid bypass. The catalog also features ET1/ET2 rigid and tension tapping collets, OZ25 (EOC25) and OZ32 (EOC32) collets conforming to DIN 6388, and complete workshop sets from 10 to 24 collets in sturdy aluminum storage cases.
Bright Tools modular boring systems provide high-efficiency boring solutions for precision housings, engine blocks, and machine structures on CNC machining centers and boring mills. Fine boring heads (NBH2084 and EWN series) feature high-precision dial screws with 0.002 mm (2 µm) vernier resolution per diameter, effortlessly achieving IT6–IT7 dimensional hole tolerances and mirror surface finishes. Rough twin-cutter boring heads (RBH, CBH, and TWN series) maximize material removal rates via either synchronized balanced cutting (doubling feed rates) or stepped-height insert configurations (for heavy depth of cut in a single pass). The modular CK / BST coupling system encompasses extensions, reducers, solid carbide boring bars, and tuned vibration-damped shanks supporting overhang ratios up to 6D–10D chatter-free.
Bright Tools static VDI tool holders (DIN 69880 / ISO 10889) provide rigid and repeatable clamping of turning and boring tools in CNC lathe turrets. Manufactured from heat-treated high-grade alloy steel with precision-ground serrations and shanks hardened to HRC 56-60, they ensure accurate alignment and maximum rigidity under heavy turning cuts. The comprehensive program covers radial turning holders (Form B1–B8 left/right/inverted), axial holders (Form C1–C4), multi-purpose holders (Form D1–D2), boring bar holders Form E1 (U-drill holders) and Form E2 (boring sleeve holders), Form E4 ER collet chuck holders, Form AL cutoff blade blocks, and Form Z2 blank plugs. Integrated coolant channels feed cutting fluid directly onto the insert cutting edge through directional ball nozzles.
Bright Tools BMT (Base Mounted Turret) driven and static tool holders are engineered for high-precision, heavy-load milling and drilling on CNC turning centers equipped with live tooling, C-axis, and Y-axis. The solid four-bolt base mount delivers superior torsional rigidity, vibration dampening, and machining accuracy compared to conventional VDI systems. Driven live heads incorporate case-hardened Gleason spiral bevel gears, matched P4/ABEC-7 angular contact spindle bearings, and high-integrity sealing systems rated for speeds up to 6,000–10,000 RPM and through-tool coolant pressures up to 70 bar. The product range includes straight (axial 0°) live holders, right-angle (radial 90°) live holders, offset Y-axis heads, dual-output heads, and adjustable angle heads (+/- 90°). Drive coupling options cover DIN 1809 tang drive, spur gear drive, and OEM couplings for Doosan (DN Solutions), Hyundai WIA, Haas, Mazak, and Victor.
Bright Tools provides a comprehensive range of CNC machine shop accessories engineered for safe, high-accuracy tool handling and setup. The portfolio includes precision retention knobs (pull studs) manufactured to ISO 7388/2, DIN 69872, MAS 403 BT (BT-40A, BT-40B, BT-50A), ANSI/CAT, and Mazak standards, through-hardened to HRC 54-58 with polished sealing surfaces and coolant bores. Tool maintenance tooling includes precision ER clamping nuts (Type A, Type UM, Mini Type M, bearing nuts, and sealed coolant ring nuts), specialized collet wrenches, hook wrenches for OZ and power chucks, torque wrench attachments for calibrated tightening, precision hydraulic machine vises, and 360° universal tool assembly tightening fixtures accommodating BT30/40/50, HSK63/100, and SK40/50 tapers.
Our technical engineering team performs rigorous dimensional validation of tooling interfaces (MAS 403 BT30/40/50, DIN 69893 HSK-A/E/F, DIN 69871 SK40/50, CAT40/50, VDI20–VDI50, and BMT45–BMT85), overhang stiffness, and clamping torque. We ensure 100% mechanical compatibility with automatic tool changers (ATC), retention knob geometry, and high-pressure coolant delivery systems.
Bright Tools precision tooling solutions are extensively deployed across precision mold making, automotive powertrain manufacturing, aerospace component machining, and heavy energy equipment fabrication. The tooling delivers exceptional chatter resistance, robust clamping force during heavy face milling, and long-term taper wear life.
All tool holders are manufactured from certified 20CrMnTi alloy steel case-hardened to HRC 58-62, while collets are formed from premium SUJ2/65Mn spring steel (HRC 44-48). Tapers are CNC ground to ISO AT3 precision, and dynamic balancing to G2.5 at 20,000–25,000 RPM protects spindle bearings from premature fatigue.
All Bright Tools holders, collets, and live tooling are supplied directly from Dezhou Bright Machinery Co., Ltd. with factory inspection certificates and dimensional test reports. We provide a 12-month manufacturer warranty, technical application support, and rapid replenishment of collets, retention knobs, and sealing spares.
