Iscar 6000867 GTN-4 IC20 Carbide Cutoff Insert 4.1mm

Product Description

The ISCAR 6000867 is a single-end carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Manufactured in the GTN-4 style with an IC20 uncoated carbide grade, this insert delivers a 4.1 mm (0.1614 inch) cutting width with a neutral lead angle and a 7-degree relief angle. The corner radius measures 0.24 mm (0.0094 inch), promoting clean, consistent entry at the cut. Machining professionals and toolroom technicians install this insert into compatible Self-Grip toolholders as a direct clamp-held replacement when regrinding or reconditioning is not practical.

This insert is suited for cut-off and grooving applications on ferrous and non-ferrous workpieces in production turning environments. The IC20 uncoated bright finish is well matched to materials falling within the C2 and C3 material grade classifications. The GTN-4 insert size and Self-Grip series designation make it a common choice in shops running standard ISCAR Self-Grip parting systems on manual or CNC lathes where controlled chip evacuation and repeatable edge geometry are required.

Key Features

• 4.1 mm (0.1614 inch) cutting width for consistent parting groove dimensions
• Neutral lead angle and neutral hand for straight-in cut-off applications
• 7-degree relief angle reduces rubbing and promotes clean chip separation
• 0.24 mm corner radius for controlled edge geometry at groove entry and exit
• Single-end design with clamp holding method for secure, repeatable seating in Self-Grip toolholders

Compatibility

Designed for use with ISCAR Self-Grip series toolholders accepting GTN insert size 4 seats. Confirm toolholder seat size and clamping method before ordering.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or toolroom technician with the machine powered off and the spindle fully stopped. Use the appropriate ISCAR torx or hex key to seat and clamp the insert firmly before resuming cuts. Inspect the insert seat for chips or debris before loading a new insert to ensure proper seating and prevent premature edge failure. Follow the toolholder manufacturer's clamping torque guidelines and do not exceed the rated depth of cut for the GTN-4 geometry.
