RUKO KES-DIN335-HSS-TiN-90°-Ø30,0mm Countersink Bit

This countersink bit with a 90° cutting angle and 30.0 mm nominal diameter is built for precise deburring, chamfering, and countersinking in steel, cast iron, non-ferrous metals, and plastics. The titanium nitride coating increases hardness, improves wear resistance, and reduces friction, ensuring clean results and long tool life.

Advantages

TiN coating provides high surface hardness, excellent wear resistance, and low friction, allowing higher cutting speeds and extended tool life. The ground profile and three flutes ensure smooth chip removal and a fine surface finish. The cylindrical shank fits standard drill chucks and collets.

Suitable for

• Steel
• Cast iron
• Non-ferrous metals
• Plastics
