Inserts & Grades
Inserts
DMP (Ø6.0 – Ø25.9 mm)
- General purpose type
- Light cutting due to sharp cutting edge
DMC (ø6.0 – ø25.67 mm)
- High accuracy type
- Innovative chiseled edge for smooth drill entry. No pre-drilling needed in 12xD drilling operation
- Double margins provides superior surface finish and hole drilling straightness
DMF (ø6.0 – ø19.8 mm)
- Flat edge design with pilot edge performs balanced drill entry
- Significantly reduced radial forces promise stable drilling for complex surfaces at drill entry and exit
- Stable drilling with long overhang up to L/D = 8 without pre-hole
DMH (ø10.0 – ø19.5 mm)
- Strong cutting edge design prevents the drill edge from fracturing during demanding processes
- Versatile and wear-resistant AH9130 grade provides extended tool life
DMN (ø10.0 – ø19.9 mm)
- Excellent welding resistance for non-ferrous metals
