Description

Solid carbide step and countersink drills can machine much faster than combination tools, and the hole sizes are more stable. Thanks to state-of-the-art NC grinding technology, our solid carbide countersinks can be designed and manufactured to desirable geometry to continuously control tolerance and cutting efficiency. With our CVD diamond coating, our countersink drills have extra-long tool life.
