Inner collant drills Advantages

Inner coolant drill additional information

Advantages

Reduction of tool- and machine-costs by means of a longer tool life. The outlet port of the coolant is close to the cutting area; consequently you can realize an optimal cooling- and lubrication effect.
High drill speed by direct cooling at the cutting point and therefore reduction of the cutting heat.
Quick and easy chip removal from the drill hole.

Design features

Grinding of the peak: grinding of the cone-shaped surface
Point angle: 118° / 170 °
Reduction of the cutting edge according to DIN 1412 Form A pages
Tool shank: extended morse taper
Coolant supply: axial or radial by morse taper
