CrazyDrill Flex, the latest member of the CrazyDrill family, combines HSS drill flexibility with a solid carbide drill's long tool life and precision.

This cutting tool design is based on a new type of carbide alloy and an accurately defined geometry. The geometry, in contrast to traditional metalworking tools, uses a flexible shank extension that allows for elasticity, which is designed to permit reliable drilling under difficult circumstances. This allows compensating for imprecise positioning as it occurs, such as with a multispindle or transfer machine.

The cutting tool is available for depths of 20× diameter and 30× diameter, in a range from 0.1 to 1.2 mm, with increments of 0.01 mm. With its size range and its capability for many different materials, the main applications are found in the micro machining of precision parts, typically in the watch and medical industry and for the machining of fuel injection components. A particular coating guarantees excellent wear properties and good thermal absorption qualities, the company says.
 
The cutting tool's particularly small diameters require accurate hole preparation with a pilot drill or an adequate centering tool.
