Kennametal 1099454 Indexable Shim Boring Bar Ivsn

Product Description

The KENNAMETAL 1099454 is an IVSN-style shim designed for indexable boring bars with a negative rake configuration. Shims of this type seat beneath the insert to maintain proper cutting geometry, protect the tool pocket, and allow precise height adjustment during boring operations. This shim is compatible with diamond-shaped indexable inserts at a 1/2 inch inscribed circle (0.5000 inches). At 3/16 inch thick and weighing approximately 0.03 pounds, it is a compact, precision-ground component installed by machinists and tool crib technicians in production and job shop environments.

This shim is intended for use in boring bar toolholders that accept IVSN-style shim seats with a 1/2 inch inscribed circle. Negative rake shim configurations are typically used in heavy-duty or interrupted-cut boring applications where insert support and rigidity are critical. The part is sold individually and is subject to a minimum order quantity of 10 units, making it appropriate for tool crib restocking or production maintenance programs.

Compatibility

Designed for indexable boring bar toolholders that accept IVSN-style shims with a 1/2 inch inscribed circle and diamond-shaped inserts in a negative rake configuration.

Installation Notes

Installation is performed by machinists or toolroom technicians during insert changeover or toolholder maintenance. Ensure the toolholder pocket is clean and free of chips or debris before seating the shim. Power down and lock out any machine spindle before servicing the toolholder. Do not use damaged or deformed shims, as improper seating can compromise insert geometry and cutting performance.
