Kennametal 7097838 A4G Grooving Insert 0.125 in Carbide Altin

Product Description

The KENNAMETAL 7097838 is a carbide grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. Manufactured in the A4G insert style with a size code of 3, it delivers a cutting width of 0.1250 inches (3.180 mm) and a maximum depth of cut of 0.1340 inches (3.40 mm). The insert is finished with an AlTiN coating applied via PVD process under the KCU10B grade, providing strong wear resistance and thermal stability at the cutting edge. With two cutting edges and a double-end configuration, it offers extended service life per insert.

This insert is suited for grooving, undercutting, and light parting applications in both ferrous and non-ferrous materials. The neutral hand orientation makes it adaptable to a range of toolholder setups. It is used in production and job-shop turning environments and is appropriate for shops running high-volume precision parts. The positive rake geometry and GMN chip breaker promote controlled chip formation and reduced cutting forces during shallow grooving passes. Installation is handled by machinists and CNC lathe operators in general metalworking applications.

Key Features

• A4G insert style with size code 3 and 0.1250 inch cutting width for consistent groove width control
• AlTiN coating via PVD process for improved heat resistance and tool life
• KCU10B manufacturer grade carbide substrate for toughness in interrupted and continuous cuts
• Double-end design with two cutting edges to maximize insert utilization
• GMN chip breaker geometry with positive rake for efficient chip evacuation in shallow grooves
• Clamp-style insert holding method for secure, repeatable seating in compatible toolholders

Compatibility

Designed as an OEM-style replacement grooving insert for A4-series toolholders accepting size 3 inserts with a 0.1250 inch cutting width and clamp-style retention.

Installation Notes

Installation is performed by a qualified machinist or CNC lathe operator. Always power down and lock out the machine before changing inserts. Seat the insert fully against the toolholder pocket and verify clamp engagement before resuming operation. Inspect the insert seat and clamping screw for wear or debris prior to each insert change to ensure proper seating and dimensional accuracy.
