Kennametal 1097597 Indexable Threading Toolholder 1.5in

Product Description

The KENNAMETAL 1097597 is a right-hand indexable threading toolholder from the Top Notch series, designed for both internal and external threading and grooving operations on CNC lathes and turning centers. The toolholder features a 1.5 x 1.5 inch square shank and an overall length of 7 inches, making it well-suited for rigid setups in medium to large turning applications. It accepts N.4R inserts secured by a clamp-style holding method, ensuring repeatable edge positioning and secure insert retention under interrupted or continuous threading cuts. Licensed machinists and CNC operators install this holder in production and job-shop environments where thread-form accuracy and insert changeover speed are critical.

This toolholder is built for threading and grooving applications in both internal and external configurations from a single holder body. With a maximum depth of cut of 0.294 inches and a back-of-bar to cutting edge dimension of 2.0 inches, it is applicable to a range of thread pitches and groove profiles on ferrous and non-ferrous workpieces. The Top Notch series designation indicates compatibility with the Kennametal Top Notch insert system. It is a multi-use tool, reducing the need for separate holders for grooving and threading operations on the same lathe turret.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before mounting or indexing inserts.
