Sumitomo 18T5W0P Grooving Insert GCM2094GG AC5015S Carbide

Product Description

The SUMITOMO 18T5W0P is a solid carbide grooving insert designed for external grooving and parting operations on CNC lathes and turning centers. Running in the GND series with a GCM insert style, it features a 0.094-inch cutting width and a maximum depth of cut of 0.709 inches. The AC5015S grade is applied with a PVD Absotech finish, providing wear resistance and thermal stability suited to a wide range of workpiece materials. With two cutting edges and a neutral hand orientation, this insert is held in place via a clamp-style toolholder. The 0.20-millimeter corner radius and 7-degree relief angle support clean grooving geometry in precision machining environments.

This insert is intended for use in production and job-shop turning applications where consistent groove width and depth control are required. The GCM2094 insert size fits corresponding SUMITOMO GND-series toolholders designed for clamp-style retention. The neutral hand configuration makes it suitable for both left- and right-hand grooving setups depending on the holder used. It is appropriate for ferrous and non-ferrous materials where PVD-coated carbide grades are recommended by the machining process engineer or programmer.

Key Features

• 0.094-inch cutting width for precise, narrow groove profiles
• Maximum depth of cut of 0.709 inches, within the 0.300 to 1.000-inch range for the GND series
• AC5015S PVD Absotech coating for enhanced wear resistance and surface finish
• Neutral hand orientation for flexible toolholder pairing
• Two cutting edges per insert for extended tooling value
• Clamp-style insert holding method for secure, repeatable seating

Compatibility

Designed for use with SUMITOMO GND-series clamp-style toolholders accepting the GCM2094 insert size. Verify toolholder seat geometry and insert pocket dimensions before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine powered off and the spindle fully stopped. Ensure the insert pocket and clamping surfaces are clean and free of chips before seating the insert. Tighten the clamp to the toolholder manufacturer's specified torque using the appropriate torque key. Confirm insert seating and runout prior to resuming cutting operations.
