Our annular cutters will increase your through hole drilling productivity while improving hole accuracy. Our annular 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 minimize kerf 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.

Annular cutters are ideal for most drilling applications including elongating holes and trepanning operations. Annular cutters are manufactured from premium high-speed steel and specially heat treated for cutting edge toughness increasing tool life between sharpening.
