Annular cutters (mag drill cutters) remove only the material at the edge of the hole rather than the whole slug, so they cut larger holes faster, cooler and with far less effort than a twist drill — perfect for structural steel, plate and fabrication work.

We stock HSS and carbide-tipped annular cutters in a full range of diameters and depths of cut, with the standard shanks that fit most magnetic drill presses. Enjoy burr-free holes and long cutter life on the toughest steel.
