Walter: Carbide Drilling Tools

Walter has developed the DC170 and is offering the first two models in dimensions 16xDc and 20xDc. The drill offers more process reliability, stability, running smoothness and efficiency than carbide drills with traditional geometries.

The drills are internally cooled. As a result, the coolant flows unimpeded, while hazardous chip jams are at the same time avoided. The manufacturer also says that the solid carbide mass directly behind the cutting edge makes the drill sturdy.

Finally, drills straight from the factory are supplied with eight visible channels that can be used as a scale for regrinding. The drills can be reconditioned up to three times, until only two cooling channels are left remaining.
