Nikcole THE-7-3/8RH.375 Grooving Cutoff Toolholder Rh

Product Description

The NIKCOLE MINI-SYSTEMS THE-7-3/8RH.375 is a right-hand indexable grooving and cutoff toolholder from the Mini-Systems series, designed for external turning operations on CNC lathes and manual turning centers. The toolholder features a 0.375 x 0.375 inch square shank and an overall length of 4.5 inches. Insert retention is handled by a screw-clamp mechanism, which provides a positive lock on compatible GIE inserts. At 0.19 pounds, this compact holder suits small-diameter and close-tolerance grooving work where rigidity and repeatability matter.

This toolholder is intended for external cut-off and grooving applications in production and job-shop environments. Its small shank profile makes it a practical choice for gang tooling setups, turret lathes, and Swiss-style turning centers where space between tool stations is limited. The right-hand configuration is suited for conventional left-to-right spindle rotation setups. Machinists and toolroom technicians working with tight radial clearances will find the Mini-Systems form factor appropriate for the application.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the turret or tool block is locked before seating or indexing the insert. Torque the insert clamping screw using the appropriate Torx or hex key specified by the insert manufacturer for GIE-style inserts. Confirm shank seating depth and tool centerline height per the machine tool manual before taking a cut.
