RUKO KES-DIN335-HSS-TiAlN-90°-Ø25.0mm Countersink Bit

The RUKO KES-DIN335-HSS-TiAlN-90°-Ø25.0mm countersink bit stands out with its TiAlN coating, which enables high cutting speeds and dry machining. The 90° angle and three-flute design produce clean, chatter-free chamfers in a wide range of materials.

Highlights

• TiAlN coating for high heat resistance up to 800°C
• Ground profile for precise, smooth countersinking
• Three flutes ensure excellent chip evacuation and surface finish
• HSS base material with high wear resistance
