CrazyDrill Pilot is a solid tungsten carbide drill which drills to depths of up to 2 x d quickly and accurately with drilling diameters of 0.4 mm (.016”) and up. The drill is universally applicable to many materials as a carbide drill for steel, steel alloys, high-alloy steels, tool steels, titanium, cast iron, brass, bronze and aluminum. It is used especially in the following sectors: mechanical engineering, medical technology, automotive engineering, injection/nozzle technology, dental, jewelry and watchmaking industry, and filter technology.
