Kennametal 1291038 Trao Indexable Turning Toolholder

Product Description

The KENNAMETAL 1291038 is a right-hand TRAO-style indexable turning toolholder designed for use on manual and CNC lathes in metal-cutting operations. Built around the K-Lock clamping system, it accepts RC..46 series inserts and delivers a neutral rake angle of 0 degrees, making it suitable for a wide range of turning applications on ferrous and non-ferrous materials. The shank measures 1 inch wide by 1 inch tall, with an overall length of 6 inches. The toolholder body is constructed from steel and uses a clamp-style insert holding method for secure, repeatable insert indexing. This holder is installed and operated by machinists, tool-and-die technicians, and CNC lathe operators.

This toolholder is intended for external turning operations on conventional and CNC lathes. It is suited for roughing and finishing passes where a neutral rake geometry is preferred. The 1 inch by 1 inch shank is compatible with standard lathe tool posts and quick-change tooling blocks that accept that shank size. With a maximum depth of cut of 1 inch and a back-of-bar to cutting edge dimension of 1.032 inches, it is well-suited for medium to heavy-duty turning work in job shop, production, and maintenance machining environments.

Installation Notes

This toolholder is installed by qualified machinists or CNC lathe operators. Before mounting or indexing inserts, power down and lock out the machine per applicable OSHA lockout/tagout procedures. Use appropriate insert-clamping torque tools and handle indexable inserts with care to avoid chipping cutting edges. Verify shank seating and clamp engagement before resuming cuts.
