Kennametal 1116320 Turning Toolholder TRAOL1615D Left Hand

Product Description

The KENNAMETAL 1116320 is a left-hand indexable turning toolholder in the TRAO style, designed for use on CNC and manual lathes in metalcutting operations. It uses a clamp-style insert holding method and accepts RC.. 152 series inserts. The shank measures 1 inch wide by 1 inch tall, with an overall length of 6 inches. The neutral rake angle at 0 degrees suits a wide range of ferrous and non-ferrous turning applications. The toolholder body is constructed from steel and is part of the K-Lock series. It does not feature coolant-through capability.

This toolholder is suited for external turning operations on production lathes, tool room equipment, and CNC turning centers where a left-hand TRAO-style holder is required. The clamp-style insert retention provides rigid, repeatable positioning, making it a practical choice for high-volume turning operations as well as general-purpose shop use. Machinists and tooling setup technicians typically specify this holder when running RC.. 152 compatible inserts on left-hand cutting passes.
