RUKO KES-DIN335-HSS-TiN-90°-5,0 mm kartio-upotuspora

Creating clean, precise countersinks in metal and plastic often requires a tool that can handle deburring and chamfering without dulling quickly. The RUKO KES-DIN335-HSS-TiN-90°-5.0mm countersink bit addresses this by combining a high-speed steel body with a titanium nitride coating, delivering sharp 90° cuts with three flutes for smooth results.

Who is it for

This countersink bit suits machinists, metalworkers, and DIY enthusiasts who need a reliable tool for deburring holes, chamfering edges, or preparing surfaces for flat-head screws in materials like steel, cast iron, non-ferrous metals, and plastics.
