Sumitomo 18T5ALK Grooving Insert AC5015S 2mm Gnd Series

Product Description

The SUMITOMO 18T5ALK is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Carrying the AC5015S manufacturer grade and an Absotech PVD coating, this insert delivers wear resistance and thermal stability suited to interrupted cuts and continuous grooving passes. It features a 2 mm cutting width, a maximum depth of cut of 20 mm, and a neutral hand orientation. The GG chip breaker geometry promotes reliable chip evacuation during grooving cycles. Machinists and CNC turning specialists working in production environments are the primary installers and users of this insert.

This insert is built for grooving applications where dimensional accuracy and surface finish consistency are critical. The GND series designation indicates compatibility with corresponding Sumitomo clamp-style toolholders designed for that insert family. It is suited for use on steel, stainless steel, and similar workpiece materials where a PVD-coated carbide grade performs effectively. The neutral hand configuration makes it adaptable to both left-hand and right-hand grooving setups depending on the toolholder orientation used.

Key Features

• AC5015S carbide grade with Absotech PVD coating for extended tool life in grooving operations
• 2 mm cutting width for precision groove sizing
• Maximum depth of cut of 20 mm, suitable for deep grooving applications
• GG chip breaker geometry for controlled chip formation and evacuation
• Neutral hand insert orientation for versatile toolholder compatibility
• Clamp-style insert holding method for secure, repeatable seating in the toolholder
• Two cutting edges per insert to extend usable life per unit

Compatibility

Designed for use with Sumitomo GND series clamp-style toolholders that accept GCM2002 insert size. Verify toolholder insert pocket specifications against insert dimensions before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or indexing the insert. Use the appropriate torque driver or clamping tool specified by the toolholder manufacturer to secure the clamp — do not over-tighten by hand or use improvised tools. Inspect the insert pocket and clamp for chips or debris before seating the insert to ensure proper contact and runout control.
