How a magnetic core drill works

The electromagnetic base locks the drill onto steel, so holes can be drilled on beams, columns and plates where they lie — horizontally, vertically or overhead. Annular (core / broach) cutters remove only a ring of metal, so they cut large holes quickly and accurately with less power than a twist drill. Use the safety strap, feed coolant to the cutter, and work on steel at least as thick as the maker recommends for full magnetic hold.

Where it is used

• Steel structures, bridges and towers
• Fabrication of beams, columns, base plates and flanges
• Railway, shipbuilding and plant maintenance
• Holes on site where the work cannot be moved
