RUKO KES-bit HSS-TiN 90° kegelsenker 10,4mm

The RUKO KES-Bit HSS-TiN 90° countersink bit with a 10.4 mm cutting diameter stands out through its titanium nitride coating, which reduces friction and extends tool life when working on steel, cast iron, non-ferrous metals, and plastics. The three-flute geometry with a 90° point angle produces clean, chatter-free countersinks for flat-head screws, while the cylindrical 6 mm shank fits standard drill chucks.

Highlights

• High-speed steel body with gold TiN coating for wear resistance
• 90° point angle matches standard countersunk screw heads
• Three cutting edges for smooth, vibration-free countersinking
• Cylindrical 6 mm shank for use in hand drills and drill presses
• Ground cutting edges for precise, burr-free results

In daily use

This countersink bit is suitable for deburring and chamfering holes in a wide range of materials up to 900 N/mm² hardness. The right-hand cutting direction and DIN 335 C geometry ensure consistent performance in both manual and machine operations.
