Kennametal 1094430 Turning Toolholder STGCL123 3/4 Shank

Product Description

The KENNAMETAL 1094430 is a left-hand indexable turning toolholder in the STGCL123 style, designed for precision external turning operations on CNC lathes and manual turning centers. It accepts TC-style trigon inserts with a 3/8-inch inscribed circle and uses a screw clamping method for positive, repeatable insert retention. The toolholder features a neutral rake angle of 0 degrees, making it suitable for a wide range of workpiece materials and cutting conditions. The steel construction provides rigidity under interrupted and continuous cutting loads. Machining professionals and tool crib personnel working with Kennametal-compatible insert systems will find this holder a direct-fit solution for left-hand turning setups.

This toolholder is suited for left-hand external turning applications in production and job-shop environments. The 3/4 x 3/4 inch shank fits standard tool blocks and quick-change tooling systems configured for that shank size. With an overall length of 4.5 inches and a back-of-bar to cutting-edge dimension of 1.0 inch, it provides consistent tool height and reach in standard OD turning setups. It is intended for use by machinists and CNC operators who require a reliable, indexable solution without coolant-through requirements.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing or seating the toolholder. Ensure the shank seat and tool block bore are clean and free of chips before clamping. Torque the insert screw according to the insert manufacturer specification using the appropriate Torx or hex key — do not overtighten, as this can fracture the insert or damage the clamp pocket.
