Kennametal 1017178 Indexable Threading Shim Sm Triangle

Product Description

The KENNAMETAL 1017178 is an SM-style shim designed for use with indexable threading toolholders. It serves as the seating interface between the toolholder pocket and the indexable insert, maintaining correct insert positioning and protecting the pocket from wear. This shim is compatible with triangular inserts and supports both left-hand and right-hand cutting directions. At 0.1575 inches thick, it provides a precise, stable foundation for threading operations. Machinists and toolroom professionals working with indexable threading systems will use this shim as a replacement or spare component during insert changes or toolholder maintenance.

This shim is suited for threading applications in production machining environments where indexable tooling is standard. The SM shim style is a recognized form factor in indexable toolholder systems. With a 5.31 mm (0.2090 inch) inscribed circle, it is sized for smaller triangular threading inserts. It applies to both left-hand and right-hand cutting configurations, making it versatile across common threading setups on lathes and turning centers. This item is sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation is performed by machinists or toolroom technicians as part of indexable insert setup or toolholder maintenance. Ensure the toolholder is removed from the machine or the machine is fully powered down and locked out before servicing the insert pocket. Seat the shim flat against the pocket floor before placing the insert to ensure correct insert height and cutting geometry. Inspect the shim for damage or deformation during each insert change and replace if the seating surface is compromised.
