RUKO KES-DIN335-HSS-TiN-90°-7.3mm Conical Countersink, 3-Flute, TiN Coated HSS, DIN 335 C, 90° Cutting Angle, 7.3 mm Cutting Diameter, 5 mm Shank, 45 mm Length

This RUKO conical countersink stands out with its TiN-coated HSS construction, offering high wear resistance and improved heat resistance for demanding countersinking, deburring, and chamfering tasks. The 90° cutting angle and 7.3 mm cutting diameter make it suitable for a wide range of materials, including steel, stainless steel, cast iron, non-ferrous metals, and plastics.

Highlights

• TiN (Titanium Nitride) coating for high wear resistance and improved heat resistance
• Precision ground from HSS (High-Speed Steel) for durability
• 3 straight flutes for efficient chip removal
• Conforms to DIN 335 C standard
• Universal application across multiple materials

In daily use

The cylindrical shank with a diameter of 5 mm fits standard drill chucks, and the right-hand cutting direction ensures smooth operation. With an overall length of 45 mm, it provides good reach and control. The straight flute design helps prevent clogging and ensures clean, precise countersinks.
