Sumitomo 18T5AME Grooving Insert AC5015S Solid Carbide

Product Description

The SUMITOMO 18T5AME is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC turning centers and lathes. Carrying the AC5015S manufacturer grade and an Absotech PVD coating, this insert delivers wear resistance and thermal stability in demanding cutting environments. The neutral hand orientation suits a wide range of grooving approaches. With a 3 mm cutting width and a maximum depth of cut of 20 mm, it handles shallow to moderately deep groove profiles. The GCM insert style pairs with compatible clamp-type toolholders in the GND series. Machinists and CNC operators working in production turning applications will find this insert suited to consistent, repeatable groove geometry.

The 18T5AME is intended for use in production turning and grooving applications where consistent chip control and surface finish are required. The RG chip breaker geometry promotes reliable chip evacuation during grooving passes. This insert is appropriate for use in both light-production and high-volume CNC turning environments on a variety of workpiece materials. It seats in GND series clamp-style toolholders sized for the GCM3015 insert format. Machinists in metal cutting, job shop, and production machining trades are the primary installers and end users.

Key Features

• Solid carbide construction with AC5015S manufacturer grade for consistent edge integrity
• Absotech PVD coating process for improved wear resistance and reduced cutting temperatures
• 3 mm cutting width with 20 mm maximum depth of cut for versatile groove profiles
• Neutral hand orientation accommodates standard grooving and parting setups
• RG chip breaker geometry supports controlled chip formation and evacuation
• 1.50 mm corner radius (0.0591 inches) provides predictable corner geometry on finished grooves

Compatibility

Designed for use with GND series clamp-type toolholders accepting GCM3015-format inserts. Compatible toolholder must support the clamp holding method specified for this insert style.

Installation Notes

Installation is performed by CNC machinists and tooling technicians. The machine spindle must be fully stopped and the turret or tool post must be in a safe, indexed position before seating or replacing any insert. Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the clamp to the correct seating torque range stated in the toolholder documentation. Inspect the insert pocket and clamp for chips or damage before seating a new insert.
