EF-Drill C-Chamfer Drills 90°

Article number TG203344.093522

  • Possible drilling depth

Solid carbide chamfer drill EF-Drill C in STEEL geometry for drilling and chamfering in steel, cast iron and non-ferrous materials.

Product features and benefits:

Economic efficiency thanks to production of drill hole and chamfer in one work step.
Four margins for improved guidance and drill hole quality.
Economic efficiency thanks to variable step lengths in mm increments.
