Kennametal 7097828 Grooving Insert A4R Carbide Altin

Product Description

The KENNAMETAL 7097828 is a double-end carbide grooving insert designed for external and internal grooving operations on CNC lathes and turning centers. Built in the A4R insert style with a size code of 4, it features a 0.1590-inch cutting width and a maximum depth of cut of 0.1360 inches. The insert is manufactured from carbide in KENNAMETAL grade KCU10B with an AlTiN coating applied via PVD process, providing high wear resistance and thermal stability across a range of workpiece materials. With two cutting edges per insert, it delivers extended tool life per unit. Licensed machinists and CNC operators working in production turning environments are the typical installers.

This insert suits grooving, parting, and undercutting applications in both roughing and finishing contexts. The full-radius geometry with a 0.0797-inch corner radius and GMN chip breaker supports controlled chip formation. The positive rake angle reduces cutting forces, making it well suited for turning steel, stainless, and similar materials where heat management and surface finish are priorities. The neutral hand orientation allows use on both right- and left-hand toolholders within the A4 series system.

Key Features

• Double-end insert provides two usable cutting edges for extended tool life
• AlTiN coating via PVD process enhances heat and wear resistance
• Full-radius geometry with 0.0797-inch corner radius supports smooth groove profiles
• GMN chip breaker promotes reliable chip control during grooving passes
• Positive rake angle reduces cutting forces on the workpiece
• Clamp-style insert holding method ensures rigid, repeatable seating

Compatibility

Designed for use with KENNAMETAL A4 series grooving toolholders that accept size 4 inserts with clamp-style holding. Verify toolholder seat size and insert style designation before installation.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine before changing inserts. Seat the insert fully in the toolholder pocket before tightening the clamp to the toolholder manufacturer specification. Inspect the insert seat and clamp for chips or debris that could affect seating and runout before resuming operation.
