About This Product
If you need clean, professional countersinks in metal, this Bosch bit is a reliable choice.

It's a 10mm taper countersink with a 4mm pilot for M5 screws.

The hex shank gives you a solid grip in your drill or driver.
It has three 90° cutting edges that slice through non-ferrous metals, alloyed and non-alloyed steel, and grey cast iron smoothly without chatter.

Bosch has been making quality tools for over 125 years, so you know the engineering is solid.

The taper design helps you get that perfect flush finish for screw heads.

Whether you're working on machinery, automotive parts, or general fabrication, this bit leaves a clean, burr-free hole.

It's the kind of small tool that makes a big difference in how your finished work looks and functions.

Tough, precise, and built to last.
