The Widia VariDrill multi-application drill is engineered to extend tool life across a range of materials, including steels, stainless steels, cast iron, nonferrous material and high-temperature alloys. It is well-suited for multipurpose drilling operations in small- to medium-sized job shops and maintenance areas. The drill features an advanced point geometry designed to reduce chipping on the cutting edge as well as a margin-less design for reduced friction. It is available in 3×D and 5×D non-coolant, and 3×D, 5×D and 8×D coolant-through lengths, with diameters ranging from 1.0 to 20.0 mm (0.0394" to 0.7874").
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.
