Kennametal 1016730 Indexable Turning Shim Sm Positive Rake

Product Description

The KENNAMETAL 1016730 is an SM-style shim designed for indexable turning toolholders. Shims seat beneath the insert to provide a stable, repeatable contact surface and to restore proper cutting geometry when the toolholder pocket shows wear. This shim is compatible with triangle-shaped inserts and features a positive rake orientation. It measures 0.125 inches thick and is sized for inserts with a 3.31 mm (0.1305 inch) inscribed circle. Machinists and toolroom technicians install this component during insert changes or toolholder reconditioning on turning centers and manual lathes.

This shim is intended for turning applications where an SM shim seat is specified. It supports left-hand, right-hand, and neutral cutting directions, making it adaptable across a range of turning toolholder configurations. Positive rake geometry helps reduce cutting forces in finish and general-purpose turning operations. The small inscribed circle size suits lighter-duty toolholders used on smaller turning centers or where tight clearance envelopes apply.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians during toolholder maintenance or insert changes. Power down and de-energize the machine tool before servicing the toolholder. Inspect the shim pocket for debris or damage before seating the shim, and ensure the shim lies flat and fully supported before torquing the insert clamp. Do not reuse a shim that shows deformation or cracking.
