AH7025 A

New AH7025 grade - Drastically improved reliability with world’s first coating technology B

Tool life comparison in grooving

Alloy steel

AH7025 Conventional grade (SCM440) C

Insert : DTE3-040 AH7025 Cutting speed : Vc = 150 m/min Feed : f = 0.17 mm/rev Groove depth : 17 mm

Machining : External grooving

No. of grooving: 60 pcs No. of grooving: 30 pcs Coolant : Wet D

Allows stable machining without peeling off, evenafter twice the cutting time versus the conventional grade. → The combination of Nano-multi-layered AlTiN Coating with high Al content and E tough substrate provides highly efficient machining in various grooving operations
