RUKO KES-DIN335-HSS-TiN-90°-Ø4,8mm verzinkboor

This RUKO countersink bit is a high-performance tool for precise chamfering, deburring, and countersinking in metal and plastic. Its 90° point angle and TiN-coated HSS construction ensure clean, chatter-free results in steel, cast iron, non-ferrous metals, and plastics.

Advantages

The titanium nitride (TiN) coating reduces friction and heat buildup, extending tool life and improving surface finish. The 3-flute design provides smooth cutting action, while the cylindrical shank fits standard drill chucks for use in drill presses, hand drills, and machining centers.

Suitable for

• Steel
• Cast iron
• Non-ferrous metals
