Our annular cutters will increase your through hole drilling productivity while improving hole accuracy. The cutters are rugged enough for structural steel fabrication, and adapt quickly and easily to most magnetic base drills,  drill presses, milling machines and CNC machining applications.  Annular cutters eliminate pre-drilling, step drilling and hole finishing operations, thus outperforming twist drills and older style annular cutters. The solid pilot locates cutter position, guides coolant to cutting edge and retracts into cutter during drilling cycle. Proven alternating tooth geometry minimises kerfs area and evenly distributes chip load to multiple cutting edges reducing horse power and drilling feed pressure. Scrap material advances away from cutting edges,  forming an easy to remove nest of chips above material surface.
