HSS Rotabor Broach Cutter (Slugger) | Weldon 19mm Shank | 12-50mm | 30mm & 50mm Cut | Castlebrook

When you need to drill large, clean holes through structural steel fast, reach for the Castlebrook HSS Rotabor Broach Cutter — also known as a slugger or annular cutter. Designed for use in magnetic drilling machines and pillar drills (with MTS adaptor), these cutters make light work of beams, girders, constructional steel, and steel plate that would defeat a conventional twist drill.
