Kennametal 1016998 Indexable Turning Shim Sm 0.188in

Product Description

The KENNAMETAL 1016998 is a solid carbide shim designed for indexable turning toolholders. Shims seat beneath indexable inserts to establish correct cutting geometry, protect the toolholder pocket from wear, and ensure repeatable insert positioning during turning operations. This shim carries the SM style designation and is sized for square inserts with a 6.71 mm (0.264 inch) inscribed circle. At 0.188 inches thick and weighing approximately 0.014 pounds, it is a precision-ground component intended for CNC and manual lathe applications where consistent insert seating is critical to surface finish and tool life.

This shim is used in turning operations on CNC lathes and manual turning centers where SM-style shim pockets are specified. It is appropriate for both production shops and toolroom environments. Machinists and tooling technicians install this shim when rebuilding or setting up indexable turning toolholders that accept square inserts with a 6.71 mm inscribed circle. It is sold individually, with a minimum order quantity of 10 pieces per order.

Key Features

• SM shim style for correct seating in compatible SM-pocket toolholders
• Sized for square indexable inserts with a 6.71 mm inscribed circle
• 0.188 inch thickness for precise insert height and geometry control
• Solid carbide construction resists wear and deformation under cutting loads
• Protects toolholder pocket from direct insert contact and damage
• Sold as single piece with minimum order quantity of 10

Compatibility

Designed for use in SM-style indexable turning toolholders that accept square inserts with a 6.71 mm (0.264 inch) inscribed circle. Verify toolholder shim pocket style and inscribed circle size before ordering.

Installation Notes

Tooling technicians and machinists install indexable shims during insert changeouts or toolholder rebuilds. Ensure the machine spindle is stopped and the turret or toolpost is fully locked out before accessing the insert pocket. Clean the shim seat and pocket thoroughly before placing the shim to prevent seating errors that affect cutting geometry. Do not modify or grind the shim, as thickness tolerance directly affects insert positioning.
