Countersink drill bit made of high-speed steel (HSS) for general applications with standard countersink angle of 90°.
The construction dimensions conform to DIN335C standards.
This type (G136) is the basic version for all countersinks and also one of the most popular models.
The high-quality HSS and the precision with which these drill bits are ground guarantee an accurate countersink that lasts twice as long as a cheaper type.
Other models include the G560, which has an extra long tool life.
For countersinking stainless steel, choose the G142 with extra-large clearance especially for stainless metals or other hard-to-machine materials.
Sovereign drill bit G570 also offers a good solution for countersinking harder materials thanks to its Cobalt(Co) alloyed HSS and extra AlTiCN coating.
