M.A. Ford offers the 2XDCE coolant-fed, high-performance drill to the Twister XD family. Designed to drill water lines in molds, the extra-long drill is suited for deep-hole drilling applications. The drilling geometry is said to increase productivity and reduce cycle time by virtually eliminating the need for a peck drilling cycle. It is available in sizes ranging from 1/8" to 1/2" (3 to 12 mm) with flute length-to-diameter ratios ranging from 12×D to 25×D.
Editor PickCan Additive Manufacturing Increase Milling Feed Rates?
With PCD tooling, yes it can. The diamond cutting edges demand a large number flutes to realize their full effectiveness. Traditional methods for making cutter bodies limit the number of flutes, but 3D printing is delivering tools with higher flute density and other enhancements as well.
