Solid carbide NC spot drill 20mm 90°
Version:
Exactly central ground point. Easy spot drilling and high shape accuracy of the centre hole. Sturdy due to short flutes.
Application:
Point angle 90° for spot drilling and countersinking in one operation when a drill of smaller dia. is used afterwards.
Note:
Use the speed for the actual hole dia. (not generally the speed for the drill outer dia.).
