Kennametal 1017174 Indexable Threading Shim Sm Triangle

Product Description

The KENNAMETAL 1017174 is an SM-style indexable shim designed for threading toolholders. It supports triangular insert geometries and accommodates both left-hand and right-hand cutting directions. At 0.126 inches thick with a 0.156-inch inscribed circle (3.96 mm), this shim provides the precise seating surface required to maintain insert positioning and cutting-edge repeatability during threading operations. Machinists and toolroom technicians install this component as part of a properly configured indexable threading assembly on CNC lathes and manual turning equipment.

This shim is intended for use in SM-style indexable threading toolholders that accept triangular inserts. Its dual-direction compatibility makes it suitable for both conventional and climb-direction threading setups. The shim seats beneath the insert to control depth and protect the toolholder pocket from wear, extending toolholder service life in production threading environments.
