PowerSpike twisted drill 4,0 mm HSSG

This new high-alloy metal drill is equipped with a new tip geometry and a three-surface-shank. The special point geometry ensures a lower heat development and
significantly higher tool life.

The PowerSpike

This fully ground high-alloy HSS drill (W6M5Cr4V2) reduces the cutting temperature and significantly increases
the tool life compared to conventional HSS metal drills. The self-centring tip makes centre punching redundant.

The special point geometry ensures a clean cutting edge profile. The three-surface-shank (from Ø 5.5) is especially
suitable for usage in battery mode and prevents slipping in the chuck.

Advantages

• Higher tool life

• Lower heat development

• No centre punching

• Three-surface-shank

• For steels up to 900 N/mm²
