70xD Drill

July 22, 2011

Walter Titex has created a new drill capable of drilling deep holes in one operation to a maximum depth of 70xD. Standard depths are up to 30xD, but depths to 70xD have been achieved in special cases.

Factors responsible for this increase in performance are essentially three structural and manufacturing features. The company produces solid-carbide blanks by applying a new method, which makes this type long twist drill possible. The finishing procedure uses a special grinding process. As is the case with all of the company’s XD drills, cooling is provided by internal coolant channels. Despite the deep drilling depth possible, high-pressure coolant systems are not necessary.

The XD70 is currently being produced as a special tool, in diameters from 0.197 to 0.472 in. Two tip coatings are available depending on the material: TFP for soft steels and XPL for cast iron.
