Walter’s DC170, a type of solid carbide, internally cooled drill is designed to drill ISO-P and ISO-K materials.

The design is a key factor in the performance, thanks to the shallow cooling grooves at the drill end. The coolant flow encompasses the entire drill point, designed to produce optimal cooling of both the drill and the workpiece interface and inhibits chip packing. The drill’s design features also add more material behind the cutting edge, which makes the drill sturdier than conventional designs, thus boosting tool life stability and process reliability, the company says.  

DC170 drills feature eight visible cooling grooves, and these can be used as a scale for regrinding. The drills can be reconditioned up to three times, until only two cooling grooves are left remaining. The drill is offered in sizes of 16×D and 20×D.
