Countersink bits for deburring and chamfering holes

Countersink drill bits create clean chamfers and remove burrs from drilled holes in metal, wood and plastic. This range of over 340 products includes HSS and HSS-E countersinks with 90-degree cutting angles for standard screw head recesses. Multi-flute designs with 3 or more cutting edges deliver smooth, chatter-free results at higher feed rates, reducing cycle time in production environments.

Cross-hole countersink bits produce precise recesses for specific fastener types requiring exact depth control. Conical cutters handle larger diameter chamfering up to 63 mm for heavy structural applications. Morse taper shanks provide rigid clamping in drill presses and milling machines, while hex and round shanks suit cordless drills and hand-held power tools for on-site work.

Sizes range from 4 mm for small fastener holes to 63 mm for large bore chamfering. DIN 335-D standard countersinks ensure compatibility with metric fastener dimensions across the full range. The selection features brands including Phantom, Bosch, Makita, International Tools, Wera, Milwaukee and more, covering both industrial manufacturing and general workshop countersinking requirements.
