Kennametal 1016728 Sm Shim Indexable Turning

Product Description

The KENNAMETAL 1016728 is an SM-style shim designed for indexable turning toolholders. Shims seat beneath the insert to establish correct cutting geometry and protect the toolholder pocket from damage during machining. This shim features a positive rake profile and is compatible with left-hand, neutral, and right-hand cutting directions, making it a versatile seating component across multiple turning setups. It is installed by machinists and toolroom technicians in production turning applications where insert stability and repeatable positioning are critical to surface finish and tool life.

This shim is intended for use in indexable turning toolholders that accept the SM shim style. It is suited for both roughing and finishing passes where positive rake geometry is required. Shops running high-volume turning operations on lathes or turning centers will find this shim applicable across a range of left-hand, neutral, and right-hand tool orientations, reducing the need to stock multiple shim variants for mixed-direction tooling setups.

Key Features

• SM shim style for indexable turning toolholders
• Positive rake geometry supports efficient chip formation and reduced cutting forces
• Compatible with left-hand, neutral, and right-hand cutting directions
• Protects toolholder pocket from insert seating wear and impact damage
• Lightweight construction at approximately 0.0128 pounds per piece

Compatibility

Designed as an OEM-style replacement shim for indexable turning toolholders requiring the SM shim style with positive rake geometry.

Installation Notes

SM shims are installed by qualified machinists or toolroom personnel during insert changeover or toolholder maintenance. Power down and lock out the machine before accessing any toolholder. Inspect the pocket seat for debris or damage before placing the shim, and ensure the shim lies fully flat in the pocket before torquing the insert clamping screw to the toolholder manufacturer specification. Do not reuse shims that show signs of deformation, cracking, or uneven wear.
