Solid Carbide Internal Cooling Twist Drill Bit

Solid Carbide Internal Cooling Twist Drill Bit For High Speed Drilling

Inner coolant drills / oil feed drills in superior quality for drilling lines in steel construction
For best inner cooling at the tool cutting edge
Our inner coolant drills always provide top quality by using high-performance materials that are manufactured in Germany. This material passes through a high advanced production process with a special heat treatment. By using coolant bore holes the drilling heat is reduced straight at the cutting edge. This creates a much higher cutting performance compared to drills without inner cooling. It is beneficial to use a suitable cooling liquid that provides an excellent cooling-performance, anti-corrosive protection, environmental compatibility and varnishing. We therefore highly recommend using the cooling liquid nencool DS 10 or nencool micro.

Coolant for inner coolant drills
It is important to use a suitable coolant, which ensures the advantages of excellent cooling performance, rust protection and environmental compatibility. We recommend the use of the high-performance coolant nencool DS 10 or nencool micro. The cooling liquid nencool DS 10 is water-soluble and is used diluted. The cooling liquid nencool micro is used as minimal lubricant. Most new drill lines use only a minimal liquid such as the nencool micro.
