- High-strength steel (Hardox)
Suitable for HARDOX® 500 (for HARDOX 550 preliminary testing is required) and for very hard materials up to 1700 N/mm² such as excavator shovels, lorry superstructures, snowploughs, agricultural machines, armour plating etc. Materials up to 1400 N/mm² can be processed using hand drills.
The drill bit for the toughest materials For hand drills and stationary power tools, DIN 338 type H, right-hand cutting, ground, multi-layer (Ti AlN)-ZrN coating, HSS-Co 8%
Advantages
- 135° turbo cutter with cross thinningPrecise tappingNo centre punching necessaryOptimal drilling progressDrilling on curved surfaces
- Robust, sturdy and long-lastingHSS-Co 8% - M42 cutting material — extremely long service lifeShort groove with reinforced core — maximum stabilityNarrow drill heel for the lowest friction resistance — robust — low risk of breakage
- Surface coatingMulti-layer ZrN coating (zirconium nitride)Increased surface hardnessPrevents built-up edgesEnhances thermal stability
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.
