HM Drills





This picture shows drills made from HM.
They are very hard and resist high temperature, thus allowing a large increase in drilling speed, without overheating.

Especially well-known is the "golden" TiN: it is the most commonly used hard coating for drills today, being used in DIY-home-machines, too.

Some people say, its popularity descended from the well-looking golden color.
Do you think so as well?? Comment on it, if you like.
