Usage
High-efficient drills with the high thermal stress resistance, higher Co content (8 %), steep helix and gread web thickness with special cutting edge are less break-sensitive. These drills are recommended for drilling of hard-to-machine materials like sheets HARDOX 400 and 500 and armour plates. |
