Iscar 6000861 GTN3W IC54 Carbide Cutoff Insert 3.1mm

Product Description

The ISCAR 6000861 is a solid carbide cutoff and grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. Manufactured to the GTN3W insert style with an IC54 grade carbide substrate, this single-end insert delivers a 3.10 mm cutting width and seats into Self-Grip style toolholders. The W chipbreaker geometry promotes reliable chip control during interrupted and continuous cuts. A 7-degree relief angle and a 0.20 mm corner radius provide clearance and edge stability across a range of workpiece materials. Machinists and CNC operators install this insert as part of a clamp-held, self-gripping tooling system suited for production turning environments.

This insert is intended for grooving and parting applications on metalcutting lathes in both job-shop and production settings. The neutral lead angle and neutral hand orientation allow straightforward, on-center parting cuts. The GTN series Self-Grip system is commonly found in high-volume turning cells where repeatable insert indexing and fast changeovers are priorities. The bright, uncoated IC54 carbide grade is suited for applications where coating would add thermal barrier concerns or where a sharp, consistent edge is preferred from the start of tool life.

Key Features

• Compatible with Self-Grip clamp-style toolholders, insert seat size 3
• Single-end design; multi-use tooling system rated for grooving and parting operations

Compatibility

Designed for use with ISCAR Self-Grip series clamp-style toolholders accepting insert seat size 3 and GTN-style inserts.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine in a fully stopped, locked-out state before insert exchange. Seat the insert fully into the Self-Grip holder pocket and verify the clamp engages the insert without rocking before resuming operation. Inspect the insert seat and clamping surfaces for chips or debris that could affect seating accuracy. Follow the toolholder manufacturer torque and clamping procedures for the specific Self-Grip body in use.
