Nikcole Mini-systems GIE7GR2.0R Gold Grooving Insert

Product Description

The NIKCOLE MINI-SYSTEMS GIE7GR2.0R GOLD is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. It features a 2.00 mm cutting width, a maximum depth of cut of 6.00 mm, and a full corner radius of 1.00 mm. The insert carries a TiN coating applied via PVD process, which improves surface hardness and wear resistance during interrupted cuts and continuous grooving passes. Material grade is C6, suited for general-purpose grooving on steel, cast iron, and non-ferrous materials. Right-hand orientation and screw-clamping holding method provide secure, repeatable seating in compatible toolholders.

This insert is intended for use in production and job-shop turning environments where consistent groove geometry is required. It belongs to the Nikcole Mini-Systems series, which is commonly used in tight-clearance grooving applications on Swiss-type and conventional CNC lathes. The GR chip breaker geometry is suited for medium-feed grooving passes where chip control is a priority. Machinists and CNC operators working in aerospace, automotive, and general machining applications will find the 6.00 mm maximum depth suitable for a wide range of groove profiles.

Compatibility

Designed as an OEM-style replacement and direct-fit insert for Nikcole Mini-Systems series toolholders accepting GIE-style inserts with a 7GR20 size code and screw-clamp holding method.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and de-energize the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key driver to secure the clamping screw to the toolholder manufacturer's specified method - do not overtighten. Verify insert seating and orientation visually before resuming cutting operations.
