Advice:

Prerequisites for drilling HARDOX®:
Stability is crucial. Hand drills are not suitable for drilling Hardox.
Minimise the distance between the drill bit and the workpiece and clamp the workpiece firmly.
Reduce the feed rate shortly before drilling through and ensure recommended feed rate and cutting speed are maintained.
