RUKO KES-DIN335-HSS-TiAlN-90°-Ø16.5mm Countersink Bit

The RUKO KES-DIN335-HSS-TiAlN-90°-Ø16.5mm stands out with its TiAlN coating, which extends tool life and allows dry machining in demanding materials. This DIN 335 C countersink is engineered for high-performance deburring, chamfering, and countersinking across steel, stainless steel, cast iron, non-ferrous metals, and plastics.

Highlights

• TiAlN coating for wear resistance and high temperature stability
• 90° countersink angle, 16.5 mm cutting diameter
• Ground from HSS for precise cutting edges
• Cylindrical shank, 10.0 mm diameter, 60.0 mm overall length
• Three flutes for smooth chip evacuation

In daily use

This countersink is a reliable choice for workshops that require consistent chamfers and deburred holes in tough alloys. The TiAlN layer reduces friction and heat buildup, so you can work without coolant in many applications. Its cylindrical shank fits standard drill chucks and collets, making tool changes quick.
