The drill for the toughest materials

DIN 1897, HSS-Co Al-Cr, coated

Application area:

For stationary machines, DIN 1897 type N extra-short, right-hand cutting, ground, aluminium-chromium coating, HSS-Co 5%

Field of Application:

Suitable for HARDOX® 450 (for HARDOX® 500 and 550 preliminary testing is required) and for very hard materials up to 1400 N/mm² such as e.g. excavator shovels, truck superstructures, snowploughs, agricultural machines, armour plating etc.

Advice:

Prerequisites for drilling HARDOX®:
Short drill construction to minimise vibration; stability is key.
Do not use in hand-held drills!
Minimise distance between drill and workpiece and clamp workpiece firmly.
Reduce feed rate shortly before drilling through and ensure recommended feed rate and cutting speed are maintained.

Advantages:

135° turbo cutter with cross grinding

• Drilling with pin-point accuracy
• No centre punch required
• Fastest drilling progress
• Drilling on convex surfaces

Reinforced drill core

• Greater cutting forces and stability
• Longer service life
• Optimised breakage resistance with all diameters
• Elasticity according to the most recent findings

Surface coating

• Al Cr coating
• Increased surface hardness
• Prevents built-up edges
• Improves thermal stability
