Características e benefícios

HPR point thinning provides excellent self-centering capabilities along with low-thrust, enabling maximum hole straightness.

4 margin lands are deal for cross holes and inclined exits, proving maximum stability.

Drills holes 5X its diameter, making it ideal for deep-hole applications.

AlTiN/AlTiSiN multi-layer coating withstands abrasive and thermal loads to increase tool life.

Patented corner radius enables long tool life and excellent hole quality by avoiding workpiece chipping during evacuation.

HA shank design reduces vibration and provides increased stability, reducing the risk of breakage. All shanks are Minimum Quantity Lubrication (MQL) ready and fulfill the DIN 6535 and 69090-03 requirements.
