Kennametal 1094427 Stgc Indexable Turning Toolholder

Product Description

The KENNAMETAL 1094427 is a right-hand STGC-style indexable turning toolholder designed for screw-on insert clamping on CNC lathes and manual turning centers. It features a 0-degree neutral rake angle and accepts TC..32.5. series inserts, including the complete TC.. 3252 family. The shank measures 0.625 inches wide by 0.630 inches tall with an overall length of 4.0 inches. The screw-on insert holding method provides secure, repeatable clamping during interrupted and continuous cuts. The toolholder body is constructed from steel for rigidity under moderate to heavy turning loads. Machinists and toolroom technicians working in production or job-shop environments rely on this holder for external turning operations.

This toolholder is suited for external turning applications on lathes where a right-hand cutting direction is required. The STGC style positions the insert at a neutral rake, making it appropriate for a range of workpiece materials when paired with the correct TC..32.5. insert grade. The head length of 0.750 inches and a back-of-bar to cutting edge dimension of 0.750 inches support consistent tool positioning on standard lathe turrets. It is not configured for coolant-through delivery, so flood or mist coolant should be applied externally at the cutting zone.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before changing inserts or seating the holder, confirm the machine is powered down and the spindle is fully stopped. Secure the toolholder in the turret to the lathe manufacturer's torque specification using the appropriate wrench — do not overtighten the insert screw beyond the insert manufacturer's recommendation. Verify tool centerline height and offset settings before initiating a cut.
