Svasatore conico RUKO KES-DIN335-HSS-TiAlN-90°-Ø4,8mm

Creating clean, precise chamfers and countersinks in metal and plastic can be challenging with standard drill bits. This RUKO countersink bit solves that problem with a 90° cutting angle and a TiAlN coating that withstands high temperatures, ensuring smooth results in tough materials.

Who is it for

Machinists, metalworkers, and DIY enthusiasts who need to deburr, chamfer, or countersink holes in steel, stainless steel, cast iron, non-ferrous metals, or plastics. Suitable for use in drill chucks and collet chucks.
