Kennametal 1097577 Indexable Threading Toolholder

Product Description

The KENNAMETAL 1097577 is a right-hand indexable threading toolholder in the Top Notch series, designed for both internal and external threading and grooving operations on CNC lathes and turning centers. The shank measures 0.5 inches wide by 0.5 inches tall, with an overall length of 3.5 inches. It accepts N.2L insert geometry and uses a clamp-style insert holding method, providing secure insert retention during interrupted and continuous threading cuts. This toolholder is intended for use by machinists and toolroom technicians working in production or job-shop turning environments.

This toolholder suits a wide range of threading and grooving applications in ferrous and non-ferrous materials. Its compact 0.5-inch square shank makes it appropriate for smaller bore work and tight-clearance setups on manual and CNC lathes. The multi-use designation means a single holder can handle both threading and grooving operations, reducing tooling changeovers. Maximum depth of cut is 0.138 inches (3.51 mm). The back-of-bar to cutting edge distance is 0.75 inches, which is relevant when calculating minimum bore diameter for internal operations.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before changing or indexing inserts. Seat the shank fully in the turret or tool block and torque the clamping screws to the machine or toolholder manufacturer specifications using calibrated tooling. Verify insert seating and clamp integrity before returning the machine to operation.
