First choice grade for grooving

AH7025 grade: Tungaloy's unique coating technology for drastically improved reliability

Tool life comparison

Alloy steel

AH7025 Conventional grade (SCM440 / 42CrMo4)

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

Machining : External grooving

Tool wear after 60 grooves Tool wear after 30 grooves Coolant : Wet

AH7025 provides stability, while preventing coating from peeling off even after machining twice the number of passes compared to the conventional grade. → The combination of Nano-multi-layered AlTiN Coating with high Al content and tough substrate provides highly efficient machining in various grooving operations.
