Kennametal 1017126 Indexable Shim Sm Square Insert

Product Description

The KENNAMETAL 1017126 is a solid carbide indexable shim designed for use with square-shaped indexable inserts in milling and turning applications. The SM shim style measures 0.188 inches thick and accommodates inserts with a 6.43 mm (0.253 inch) inscribed circle. Solid carbide construction provides the rigidity and wear resistance required to maintain accurate insert seating under the cutting forces typical of metal removal operations. This shim is installed by machinists and toolroom technicians as a precision seating component within indexable toolholders.

This shim is suited for both milling and turning setups where proper insert support and consistent pocket depth are critical to tool life and surface finish. It is intended for use with square indexable inserts carried in SM-style shim seats. The 0.188-inch thickness makes it appropriate for toolholders designed to that pocket specification. Typical applications include production machining environments where indexable tooling is used on CNC lathes, machining centers, and manual turning equipment.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Disassemble the toolholder and clean the insert pocket before placing the shim to ensure proper seating and accurate insert height. Use the manufacturer-recommended torque specifications for the clamping screw as indicated in the toolholder documentation. Inspect the shim for damage or wear during every insert change to maintain consistent cutting geometry.
