Kennametal 1097234 Threading Toolholder 1x1 Inch Left Hand

Product Description

The KENNAMETAL 1097234 is an indexable threading toolholder from the Top Notch series, designed for both internal and external threading and grooving operations on metalworking lathes and turning centers. It features a left-hand orientation with a 1 x 1 inch square shank and an overall length of 5 inches. The toolholder uses a clamp-style insert holding method and accepts N.3R insert style inserts with a style NE toolholder profile. Licensed machinists and CNC turning specialists install this holder in production shops and job shops running threaded components in steel, cast iron, and similar materials.

This toolholder is suited for both light production and job-shop turning applications requiring precise thread form control. Its multi-use design supports switching between threading and grooving operations without changing holders, reducing setup time on manual lathes and CNC turning centers. The 0.75 inch head length and a maximum depth of cut of 0.21 inches make it a practical choice for standard thread pitches on small to medium diameter workpieces. A back-of-bar to cutting edge distance of 1.25 inches provides clearance geometry typical for internal and external threading configurations.
