RUKO KES-DIN335-HSS-TiN-90°-Ø11,5mm avellanador cónico

Countersink bit with 90° cutting angle and 11.5 mm cutting diameter, made from high-speed steel with titanium nitride coating for extended tool life. The three-flute design with straight cutting edges ensures clean, chatter-free countersinking in a wide range of materials.

Advantages

The TiN coating reduces friction and heat build-up, allowing higher cutting speeds and longer intervals between regrinds. Fully ground flutes provide precise concentricity and smooth chip evacuation.

Suitable for

• Deburring and chamfering drilled holes
• Countersinking for flat-head screws
• Steel, cast iron, non-ferrous metals, plastics, and wood
