Walter drill line expansion

Waukesha, Wisconsin – The DC170 high performance drill for steel and cast iron has become more attractive for a wide array of applications with the introduction of several new depths-of-cut sizes. In addition to the currently available drill lengths of 16xD and 20xD, users can now choose dimensions of 3xD, 5xD, 8xD, and 12xD. Custom-made versions can also be supplied via the Walter Xpress Service for rapidly available special tools.

Like the previous sizes, the new sizes are unique in both appearance and performance. Its appearance, with an innovative land design that orients the margins radially and with a copper-color finish (DPP Coating), provides performance.

The design of the lands is a key factor in this performance, thanks to their shallow cooling grooves at the drill end. The coolant flow encompasses the entire drill point, producing optimal cooling of the drill and the workpiece. This is particularly important given the high temperatures generated during drilling. The drill’s design also adds more material behind the cutting edge which makes the drill sturdier than conventional designs.

The ability to control the coolant flow contributes to surface finish, helping avoid rework. The new design reduces vibration, which also enhances hole quality.
