Kennametal 1097235 Threading Toolholder Left Hand 1.25 in

Product Description

The KENNAMETAL 1097235 is an indexable threading toolholder designed for both internal and external threading operations on metal lathes and turning centers. Built in the Top Notch series, it accepts N.3R inserts held by a clamp-style insert holding method, providing secure and repeatable cutting edge positioning. The toolholder features a 1.25 x 1.25 inch square shank and an overall length of 6 inches. Left-hand orientation makes it suited for specific spindle directions and workpiece setups. Licensed machinists and CNC turning specialists install this toolholder in production and job-shop environments where consistent thread-form quality is required.

This toolholder is used in both light production and general-purpose turning applications where threading is performed on a lathe or CNC turning center. The left-hand configuration positions the cutting action for right-to-left feed or specific chuck orientations. With a maximum depth of cut of 0.21 inches and a head length of 0.75 inches, it handles standard threading passes on a variety of workpiece diameters. The back-of-bar to cutting edge distance is 1.5 inches, which is relevant for boring bar clearance and tool-post setup.

Installation Notes

Installation is performed by machining professionals familiar with lathe and CNC turning center tooling setups. Ensure the machine spindle is fully stopped and the turret or tool post is locked out before mounting or removing the toolholder. Confirm insert seating and clamp torque per the insert manufacturer guidelines before taking threading passes. Verify tool height alignment to centerline before engaging the threading cycle.
