Kennametal 1097600 Threading Toolholder 1.25 in Shank

Product Description

The KENNAMETAL 1097600 is an indexable threading toolholder designed for both internal and external thread-cutting operations on CNC lathes and manual turning centers. Part of the Top Notch series, this right-hand toolholder accepts N.4R inserts held by a clamp-style insert holding method. The shank measures 1.25 x 1.25 inches square with an overall length of 5 inches. It supports grooving and threading applications, making it a versatile single-body solution for shops running multiple thread profiles. The toolholder weighs 2.04 pounds and is identified by the MSC/Manufacturer reference NSR/L204C.

This toolholder is suited for production and job-shop turning operations where both grooving and threading are required from a single holder. The Top Notch series design is commonly used in horizontal and vertical turning centers. The clamp-style insert retention provides secure, repeatable positioning during interrupted cuts and high-feed threading passes. It is appropriate for threading in both ferrous and non-ferrous materials depending on the insert grade selected. Machinists and CNC operators working in metalworking and precision machining environments are the primary installers of this toolholder.

Key Features

Compatibility

Designed to accept N.4R series inserts using the clamp holding method within the Top Notch toolholder system. Compatible insert style is N.4R as specified by the manufacturer. Verify insert grade and geometry selection against your specific thread form and material requirements before ordering inserts separately.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before mounting or removing the toolholder from the turret. Seat the shank fully in the tool block and verify tool centerline height before running. Inspect the insert clamp and seating pocket for chips or damage each time the insert is indexed.
