Description
Version:
Special surface treatment, resulting in reduced tendency to edge build-up and improved chip evacuation.
Top quality high performance twist drills.
Cutting edge section ≤ 26.5 mm ⌀ ground from solid, > 26.5 mm ⌀ milled. This ensures high concentricity and pitch accuracy, and precision ground point up to 40 mm ⌀.
With shape A point.
