Available initially in diameters of 3 to 16 mm – for depths up to 16xD and 20xD – the drills are designed for use on ISO P and K materials, and are particularly suited for difficult operations that include cross holes and inclined exits, says Walter.
Offering through-tool-coolant, the DC170's eight channels formed by the land design allow for good coolant flow and unimpeded chip clearance. Furthermore, as the alignment of the lands enables coolant to continuously surround the drill, vibration is also minimised.
Walter says the drills can be reground up to three times and stay within DIN standards.
