CrazyDrill Crosspilot is a solid carbide drill bit (one could also call it a milling drill bit for metal) which drills pilot holes quickly and accurately on inclined, convex or even concave surfaces with a drilling diameter of 0.4 mm (.016”) and up. The tungsten carbide drill for steel is universally applicable to many materials (steel alloys, high-alloy steels, tool steels) and to other metals such as titanium, cast iron, brass, bronze or aluminum. It is used especially in the following sectors: mechanical engineering, medical technology, automotive engineering, injection/nozzle technology, dental, jewelry and watchmaking industry, die making, food industry, aviation industry, hydraulics, pneumatics, fittings, electronics and electrical engineering, and filter technology.
