Kennametal 1099461 Indexable Grooving Shim Sm Style

Product Description

The KENNAMETAL 1099461 is an SM-style indexable shim designed for grooving tool applications. This shim seats beneath a cutting insert in an indexable toolholder, maintaining precise insert positioning and protecting the toolholder pocket from damage during grooving operations. It is compatible with rectangular inserts and supports both left-hand and right-hand cutting directions. With an inscribed circle of 0.125 inches and a thickness of 0.188 inches, this shim provides consistent seating geometry for repeatable tool setup. Machinists and tooling technicians working in production turning, parting, and grooving applications rely on shims like this one to extend toolholder life and maintain insert stability under cutting load.

This shim is suited for use in indexable grooving toolholders that accept SM-style shim components with a 0.125-inch inscribed circle insert seat. It is appropriate for both manual and CNC turning centers performing grooving, parting, and similar interrupted-cut operations. The rectangular insert shape compatibility makes it a common fit in standard grooving tool configurations found in light to medium machining environments. This is a replacement or spare component sold individually, with a minimum order quantity of 10 units per order.

Installation Notes

Installation is performed by qualified machinists or tooling technicians during insert changeover or toolholder maintenance. Power down and de-energize the machine before accessing the toolholder. Ensure the shim pocket is clean and free of chips or debris before seating the shim to maintain proper insert height and clamping geometry. Do not reuse a shim that shows signs of deformation or seating surface wear, as this can compromise insert stability and surface finish.
