RUKO KES-DIN335-HSS-90°-28,0mm kartioupotuspora

This countersink bit is built around a 90° cutting angle and a 28.0 mm cutting diameter, making it a direct fit for DIN 335 C countersinking tasks where a clean, consistent chamfer is required. The HSS body with bright finish keeps the cutting edges sharp across steel, cast iron, non-ferrous metals, plastics and wood.

Highlights

• 90° countersink angle for standard chamfer geometry
• 28.0 mm cutting diameter with 10.0 mm cylindrical shank
• HSS construction with bright, uncoated surface
• Three-flute ground profile for smooth cutting action
• Right-hand cutting direction

In daily use

The conical shape and ground cutting edges make deburring and countersinking straightforward on a range of materials. The 10.0 mm shank with h8 tolerance fits standard drill chucks, while the three flutes help clear chips and reduce chatter during operation.
