Trepanation drills, also called crown drills and trepanation cutters, allow you to drill holes in a full material (steel), without the need for drilling.
They are made of HSS high-speed steel.
Drill holes do not require deburring, and the smoothness and precision of execution are closer to reaming than drilling.
The range of offered drills from 12mm to 65mm allows you to drill holes with a depth of up to 30mm.
Trepanation drills are designed for drills with a magnetic foot.
It is required to use a guide pilot when drilling suitable for the type of drill.
