RUKO KES-DIN335-HSS-TiN-90°-Ø5.8mm Countersink, HSS TiN Coated, 90° Cutting Angle, 5.8 mm Cutting Diameter, 5 mm Shank, DIN 335 C

Countersink bit for deburring, chamfering, and countersinking in steel, cast iron, non-ferrous metals, and plastics. The 90° cutting angle and 5.8 mm cutting diameter produce clean, accurate chamfers. The titanium nitride (TiN) coating reduces friction and improves heat resistance, extending tool life. Manufactured from high-speed steel (HSS) with a ground profile for precise cutting edges. Three flutes ensure smooth chip removal and a fine surface finish. Cylindrical shank with 5 mm diameter and h8 tolerance fits standard drill chucks. Overall length 45 mm. Complies with DIN 335 C.

Advantages

TiN coating for reduced wear and higher cutting speeds. Ground flutes for clean cutting action. Right-hand cut for conventional drilling machines. Suitable for a wide range of materials.
