Kennametal 1291031 Lh Trao Turning Toolholder RC..46

Product Description

The KENNAMETAL 1291031 is a left-hand TRAO-style indexable turning toolholder designed for precision metal-cutting operations on CNC and manual lathes. Built on the K-Lock series platform, it features a 1.25-inch by 1.25-inch square shank and an overall length of 6 inches. The holder accepts RC..46 series inserts held by a clamp-style mechanism and runs a neutral rake angle of 0 degrees. Machined from steel, it delivers the rigidity required for consistent turning performance. This toolholder is intended for use by machinists and toolroom technicians in production and job-shop environments.

The 1291031 is suited for external turning applications where a left-hand cutting orientation is required. The neutral rake geometry makes it a versatile choice across a range of workpiece materials and cutting conditions. The K-Lock clamping system provides secure insert retention during interrupted and continuous cuts. Coolant-through capability is not included in this holder configuration. It is a single-purpose, non-multi-use toolholder matched to RC..46 insert geometry with a 0.5-inch inscribed circle.
