AirMAB Pneumatic Drills and Compact Systems
For explosive environments and hazardous offshore processing areas, BDS offers the ATEX-compliant AirMAB 5000 pneumatic magnetic drill featuring a rotary vane air motor and high-coercivity permanent magnet base.
For confined structural cavities and narrow web sections, low-profile angle drills MAB 150 and MAB 155 offer minimum operating heights from 180 mm. The PipeMAB chain clamping assembly enables precise mounting on process pipes with outside diameters from 80 to 500 mm.
ATEX pneumatic motor, 180 mm low profile clearance, chain clamping fixtures for pipes 80–500 mm.
EKF Edge Beveling Machines and AutoCUT 500
For weld seam preparation and deburring, BDS engineers portable hand-guided beveling machines of the EKF 300, 450, 500, and 600 series, featuring infinitely adjustable chamfer angles from 15° to 60°, along with radius cutters for coating prep.
The self-propelled AutoCUT 500 plate edge milling unit drives autonomously along steel plate edges at speeds up to 1.5 m/min, generating precision chamfers up to 30 mm width on plates up to 40 mm thick using indexable carbide inserts.
Chamfer angle 15° to 60°, bevel width up to 30 mm, plate thickness up to 40 mm, indexable carbide inserts.
BDS Annular Cutters, Tool Holders and Accessories
The BDS genuine tooling range covers high-performance annular cutters forged from cobalt alloy steel HSS-Co 8, carbide-tipped TCT cutters with staggered tooth geometry, Weldon-shank twist drills, and countersinks.
To facilitate rapid tool changeovers, BDS supplies Keyless quick-change arbors, Morse Taper holders MK 2, MK 3, MK 4 with internal coolant feed, torque-limiting tapping chucks, and precision ZAK spring ejector pilot pins.
HSS-Co and TCT cutters 12–130 mm, depths 30, 55, 110 mm, Weldon adapters, MT2/3/4 arbors, ZAK pins.
Parameters for drilling machine selection
Core and twist drilling diameter range, required depth of cut, power supply voltage (230V or 110V), reversible motor for tapping, and base steel thickness.
Tooling and assemblies for BDS machines
Machine model and serial number, Weldon arbor part numbers, Keyless quick-change holders, ZAK pilot pins, indexable carbide inserts for EKF bevelers, and motor assemblies.
Classification of MAB drilling machine series
The BDS Maschinen magnetic drilling range is categorized into four series. The MABasic series is optimized for standard fabrication without complex electronics, featuring high-torque motors and direct 19 mm Weldon mounting.
The MAB ProfiSTART series adds two-speed gearboxes, internal cable management, and reversible motor options for tapping.
Heavy-duty MAB ProfiPLUS units are built for continuous structural fabrication: MAB 825, 845, and 1300 models feature four-speed oil-bath transmissions, Morse Taper 3/4 spindles, and hole drilling up to 130 mm diameter. The AutoMAB series provides autonomous quill feed.
Annular core drilling mechanics and cooling
Annular cutters remove metal along the hole perimeter, reducing machine energy consumption by three to four times compared to solid twist drilling.
A precision spring-loaded ZAK pilot pin centers the cutter, activates the internal coolant flow into the cut zone, and ejects the metal slug upon completion of the cut.
For vertical or overhead applications, BDS cutting pastes are recommended to prevent fluid ingress into electrical motor components.
Thread tapping with reversible spindle drive
Models in the ProfiSTART and ProfiPLUS series with electronic speed control feature bidirectional spindle rotation. This enables tapping blind and through holes from M10 to M42 directly on installed structural steel without hauling workpieces to stationary radial drills.
To safeguard taps from mechanical fracture, specialized tapping chucks with quick-change collets and integrated adjustable torque slip clutches are deployed.
AutoMAB automated feed for serial production
AutoMAB 350 and AutoMAB 450 drilling units boost throughput during repetitive drilling in beams, channels, and heavy flanges. The operator positions the drill, activates the electromagnet, and starts the cycle; an onboard controller manages an independent servo feed drive.
The system monitors motor load: upon encountering hard spots, feed rate dynamically eases to prevent tooth chipping. Once penetration is complete, the carriage retracts, and power turns off.
Railway track drilling with RailMAB systems
RailMAB 960 and 965 track drilling machines are engineered for permanent way maintenance. For remote track sections, the RailMAB 960 incorporates an autonomous four-stroke petrol engine.
Clamping onto the rail is achieved via a mechanical clamp with calibrated profile shoes tailored to the rail web profile. This eliminates reliance on electrical supply for magnetic holding and ensures perpendicularity for joint fishplate bolt holes.
Pneumatic drilling solutions for hazardous areas
In petrochemical refineries, offshore platforms, and gas transfer facilities, standard spark-generating electric tools are restricted by plant safety rules. For such operating conditions, BDS provides the AirMAB 5000 pneumatic magnetic core drill.
Spindle torque is delivered by an 830 W rotary vane pneumatic motor running off 6-bar compressed air, while hold-down force is provided by a permanent neodymium magnet base requiring zero electrical power.
Weld edge preparation with EKF and AutoCUT
To ensure high-integrity weld seams meeting ISO standards, plate edges must feature uniform bevel geometry free from thermal hardening. BDS EKF 450, 500, and 600 portable bevelers incorporate an adjustable guide plate that allows stepless chamfer angle setting from 15° to 60°.
5 m/min, creating consistent weld prep chamfers.
Keyless arbors, tooling, and magnetic adhesion safety
To minimize changeover downtime, BDS developed the Keyless arbor system, allowing operators to swap Weldon cutters in seconds without hex wrenches. Safe operation of magnetic drills requires sufficient base metal thickness; a minimum of 10 to 12 mm is recommended for full rated holding power.
BDS ProfiPLUS and ProfiSTART machines incorporate an LED indicator that alerts operators when magnetic adhesion is marginal to avoid slippage.
