Cobalt drills are incredibly strong, so they are ideal for drilling into very hard, abrasive and difficult to machine materials. They can perform well at high temperatures  - because cobalt drills can resist heat for extended periods of time, they don’t need to be cooled and cutting fluid doesn’t need to be used.

• Our PTI cobalt drill bits have a split point, which makes centre punching unnecessary and avoids skidding
