Kennametal 1095671 Indexable Threading Toolholder

Product Description

The KENNAMETAL 1095671 is an external, right-hand indexable threading toolholder from the Top Notch series, designed for precision threading and grooving operations on CNC lathes and turning centers. Built to NAS toolholder style, it accepts N.2R inserts held in place by a clamp-style insert holding method. The shank measures 0.375 x 0.375 inches square, and the overall length is 6.0 inches, making it well suited for tight turret setups where compact reach is required. A maximum depth of cut of 0.138 inches supports controlled thread-forming passes. Machinists and toolroom professionals in production and job-shop environments will find this holder a straightforward fit for external threading applications.

This toolholder is intended for external threading and grooving operations on standard lathes and CNC turning equipment. The 3/8-inch square shank fits toolpost and turret positions sized for that cross-section. With a head length of 0.75 inches and a back-of-bar to cutting edge measurement of 0.375 inches, it provides consistent cutting geometry for threading passes on workpieces where access and clearance are standard. It is a multi-use tool capable of handling both threading and grooving tasks with compatible Top Notch N.2R inserts.
