Kennametal 1016594 Shell Mill Shim Sm Indexable

Product Description

The KENNAMETAL 1016594 is an SM-style shim designed for use with indexable shell mill toolholders. Shims of this type seat beneath indexable inserts to set the correct cutting edge height, protect the pocket floor from insert wear, and maintain consistent tool geometry across insert changes. At 0.0141 pounds, this is a precision-ground, low-mass component that directly affects surface finish and dimensional accuracy in milling operations. It is installed by machinists and toolroom technicians as a routine part of insert indexing and holder maintenance on CNC and manual milling machines.

This shim is intended for use in shell mill toolholders operating with indexable insert systems. It fits a specific set of KENNAMETAL KSSISR-series holders and is suited to both production floor and job-shop environments where shell mills are used for face milling, shoulder milling, or profiling operations. The SM shim style is a defined seat geometry within the KENNAMETAL indexable tooling system and is not interchangeable with other shim styles.

Installation Notes

Installation is performed by a machinist or toolroom technician during insert indexing or holder maintenance. Power down and lock out the machine spindle before accessing the tool holder. Ensure the shim seat and pocket floor are clean and free of chips or burrs before placing the shim to avoid improper seating. Use only the correct SM-style shim for these holders; substituting an incorrect shim style will compromise insert seating and cutting performance.
