Kennametal 1017176 Indexable Threading Shim Sm Triangle

Product Description

The KENNAMETAL 1017176 is an SM-style shim designed for indexable threading toolholders. It seats between the toolholder pocket and the insert, providing a stable, repeatable seating surface that maintains insert height and protects the pocket from wear. The shim measures 0.126 inches thick and is compatible with triangular inserts having a 3.96 mm (0.156 inch) inscribed circle. Suitable for both left-hand and right-hand cutting directions, this shim is a precision component used by machinists and toolroom technicians in CNC turning and threading operations.

This shim is used in indexable threading setups on CNC lathes and turning centers. It is appropriate for both left-hand and right-hand threading applications. The SM shim style is specific to toolholders that require this pocket geometry, making correct style identification critical before ordering. Typical use is in production threading environments where insert indexing frequency is high and pocket protection is a maintenance priority.

Installation Notes

Shim installation and insert indexing should be performed by qualified machinists or toolroom personnel. Ensure the machine is fully powered down and the spindle is locked before accessing the toolholder pocket. Clean the pocket thoroughly before seating the shim to prevent seating errors caused by chips or debris. Follow the toolholder manufacturer torque specifications for clamping hardware.
