Kennametal 1095574 Indexable Threading Toolholder 0.5 in

Product Description

The KENNAMETAL 1095574 is a right-hand indexable threading toolholder from the Top Notch series, designed for both internal and external threading and grooving operations on metalworking lathes and turning centers. The toolholder features a 0.5 x 0.5 inch square shank and an overall length of 6 inches, making it compatible with standard toolpost and turret setups in the NAS toolholder style. It accepts N.3R insert geometry and uses a clamp-style insert holding method for secure, repeatable positioning under cutting loads. This holder is specified by machinists and CNC lathe operators working in production and job-shop environments.

The 1095574 is suited for threading and grooving applications on small- to mid-size turning equipment. With a maximum depth of cut of 0.21 inches and a head length of 1.25 inches, it handles a range of thread forms and groove profiles. Its multi-use design allows a single holder to cover both threading and grooving passes, reducing the number of tools required in a turret setup. Typical installations involve ferrous and non-ferrous workpiece materials in both production runs and low-volume precision work.
