Nikcole Mini-systems GIE7SG1.85RGOLD Grooving Insert

Product Description

The NIKCOLE MINI-SYSTEMS GIE7SG1.85RGOLD is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Built to the GIE insert style with an SG chip breaker geometry, it delivers a 1.85 mm cutting width and a maximum depth of cut of 6.00 mm. The insert is finished with a PVD-applied TiN coating over a C6 carbide grade substrate, improving wear resistance and edge life during ferrous and non-ferrous machining. It is screw-held and configured for right-hand cutting. Machinists and tooling specialists in precision machining shops install this insert as part of a Nikcole Mini-Systems grooving toolholder setup.

This insert is suited for grooving, parting, and recessing applications on lathes operating in production and job-shop environments. The 1.85 mm cutting width targets narrow-groove work where dimensional accuracy and surface finish are critical. The SG chip breaker geometry supports controlled chip evacuation at moderate feed rates. The screw-clamping method provides repeatable seating and quick indexing during high-volume runs. This insert is intended for use by machinists working with compatible Nikcole Mini-Systems grooving toolholders.

Key Features

• 1.85 mm cutting width for narrow-groove precision work
• Maximum depth of cut of 6.00 mm, within the 5.00 to 10.00 mm range class
• Solid carbide C6 grade substrate for wear resistance in general-purpose turning
• PVD TiN coating applied for improved tool life and reduced edge buildup
• SG chip breaker geometry for controlled chip flow during grooving operations
• Screw-held insert mounting for secure, repeatable positioning in the toolholder
• Right-hand cutting configuration; overall length 17.00 mm, overall width 2.00 mm

Compatibility

Designed for use with compatible Nikcole Mini-Systems GIE-series grooving toolholders that accept the 7SG insert size. Verify toolholder seat dimensions and clamping screw specification before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or replacing the insert. Use the correct torque driver or hex key specified by the toolholder manufacturer for the clamping screw - do not overtighten, as this can fracture the carbide insert body. Confirm proper seating and clearance before resuming cutting operations.
