Kennametal 1095576 Indexable Threading Toolholder

Product Description

The KENNAMETAL 1095576 is an indexable threading toolholder designed for both internal and external threading and grooving operations on CNC lathes and turning centers. Built in the Top Notch series with a NAS toolholder style, it accepts N.2R inserts secured by a clamp-style insert holding method. The right-hand orientation and 0.625 x 0.625 inch square shank make it a standard fit for many lathe turret setups. Overall length is 4.5 inches, with a head length of 0.75 inches and a maximum depth of cut of 0.138 inches. Machinists and CNC turning specialists install this holder in production and job-shop environments where reliable, repeatable thread form is required.

This toolholder is suited for threading and grooving applications across a range of materials on manual and CNC lathes. The 0.625 x 0.625 inch shank fits standard lathe tool blocks and turret stations sized for 5/8 inch tooling. Its multi-use capability means a single holder can be used across internal and external threading passes without switching holders, reducing changeover time on the machine. The back-of-bar to cutting edge dimension is 0.625 inches, which is relevant for boring bar setups and internal threading clearance calculations.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or indexing inserts or mounting the holder in the turret. Verify shank seating and clamp torque against the machine tool manufacturer specifications before resuming cuts. Do not exceed the rated maximum depth of cut of 0.138 inches to avoid insert fracture or holder damage.
