8. Frequently asked questions
Does 50L specify working length?
No. L specifies overall length. Working length is an earlier, separate number in the size designation.
Is working length the drilling depth?
Working length is a tool dimension. It does not by itself specify maximum drilling depth.
What point angle does a Ø3 mm drill have?
120°. The 130° angle applies to diameters greater than 3 mm.
Does the price cover a drill set?
The price covers one drill in the selected size.
