Cordless Magnetic Base Drill

Anchor Anywhere, Drill Precisely, No Cord Required

Magnetic base drills solve a problem unique to steel fabrication and structural work: how do you drill a precise, perpendicular hole into a vertical or overhead steel surface without a fixed mounting point? Our cordless magnetic base drill answers with a high-holding-force electromagnetic base that clamps to ferrous steel of 6mm thickness or greater, generating up to 1,500 kg of holding force from a single 18V battery — enough to safely support the drill in any orientation, including straight overhead, while the annular cutter bites into the steel surface.

The drill head travels on a precision rack-and-pinion feed mechanism, providing smooth, controlled downward pressure that prevents cutter chatter and extends annular cutter life significantly compared to freehand drilling pressure. The machine accepts annular cutters from 12mm to 50mm diameter using a standard weldon shank arbor, with a cutting depth capacity of up to 50mm in structural steel — sufficient for the vast majority of bolt-hole and pin-hole applications in steel erection and machinery installation.

Safety is engineered into the magnetic system at a fundamental level: an electronic monitoring circuit continuously verifies magnetic holding force and will not permit the motor to engage unless full clamping force is confirmed, preventing the dangerous scenario of a drill losing its grip mid-cut. A backup safety chain or strap point is provided for overhead applications as a secondary restraint per industry safety protocols. The cutting fluid reservoir feeds coolant directly to the cutter tip via gravity or pump-assisted delivery, extending cutter life and preventing the heat buildup that causes premature annular cutter failure in continuous-duty applications.

Constructed for structural steel fabricators, riggers, and pipeline construction crews, the unit's cast aluminum base and steel guide rails withstand the repeated mounting and dismounting cycles of daily field use. The 18V battery platform eliminates the generator and extension cord logistics that complicate overhead and remote-location drilling, while delivering performance that matches corded magnetic drills in cutting speed and hole quality. For any application requiring precise, perpendicular holes in structural steel away from a bench or fixed power source, this magnetic base drill delivers dependable, field-proven performance.
