Tips for correct use of drills

Kyocera Unimerco offers a full range of standard drills in several qualities and we are very experienced in recommending correct choice of drills.

A very common challenge when drilling holes, is the tear out on the edge of the hole. If the edge is damaged, it requires expensive post processing. To get rid of the post processing it is important to have correct distance between the rakers and the spurs.

If you experience challenges with your current drills or if you are about to order new, we recommend you to take a look at the below scheme.
