Head-changeable drill for drilling large holes
Unique clamping concept and two effective cutting edges on the drill head provide excellent hole quality and high productivity
Applications & Features
Applications
Features
1. Two effective cutting edges
• The drill head with two effective cutting edges provides high productivity and reliability.
2. Unique clamping system
• The drill head change is possible without removing the drill body from the tool holder or the spindle, eliminating re-adjustments.
• Asymmetric shaped drill head not only secures stability in heavy machining but also error-proofs drill head installation.
• The drill body has a wide supporting area for the drill head for rigid insert clamping.
Inserts & Grades
Inserts
SMP (ø20 – ø41 mm)
- General purpose type
SMF (ø20 – ø41 mm)
- Provides greater resistance to radial forces, improving machining stability during the drilling of irregular surfaces or workpieces with low rigidity
- Coated with wear resistant PVD grade, AH9130
SMC (ø26 – ø33 mm)
- Pre-drilling is unnecessary
- Outstanding drilling stability
- Sophisticated geometry prevents cutting edge fracture and burr formation on the workpiece
Grades
AH725
-
P15 – P30 / M15 – M30 / K25 – K30 / S15 – S25
-
Good balance between wear and chipping resistance
-
Suitable for machining steel and stainless steel under general cutting conditions
AH9130
- P15 – P35 / M25 – M35 / K10 – K25 / S15 – S30
- High wear resistance
- Designed for drilling various materials
