Inner coolant drills Advantages

Inner coolant drills / oil feed drills in superior quality for drilling lines in steel construction

Advantages

• Reduction of tool and machine costs through 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.
• Stable mounting in the drill spindle by means of morse taper MK3 and MK4. When using a drill with MK2, a reducing sleeve to MK3 can be used.
• The inner cooling channel makes the drill much more stable than with an attached cooling channel

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

• Optimal hardening and tempering process for long durability

Constant high quality

• Using selected and patented high performance steels
• Optimal/solid construction
• Special heat treatment
• Use of modern production processes in Germany
• rregular quality checks
• Optimal packaging

Field of Application

uitable for drill depths of 5xD and 7xD, horizontal and vertical drilling; suitable for drilling machines and machine centers in order to drill structural steel and cast steel (alloyed and unalloyed), steels with high material strength, profiles and laminations etc.
