Kennametal 1017298 Indexable Shim Icsn 5/8 Inch Boring Bar

Product Description

The KENNAMETAL 1017298 is an ICSN-style shim designed for indexable tooling systems used in boring bar and turning applications. At 3/16 inch (0.1875 inch) thick and sized for a 5/8 inch inscribed circle, this shim seats beneath a diamond-shaped insert to maintain precise cutting edge height and negative rake geometry. It is a consumable tooling component installed by machinists and tool crib technicians working with indexable boring bars and turning tool holders. Proper shim selection directly affects insert seating stability, tool life, and dimensional accuracy in metal-cutting operations.

This shim is suited for use in CNC turning centers, manual lathes, and boring bar assemblies that accept diamond-shaped inserts with a 5/8 inch inscribed circle and require negative rake geometry. It is typically used in production machining environments where consistent insert positioning is critical. The ICSN shim style is a standard configuration across many indexable tool holder platforms in both roughing and finishing operations on ferrous and non-ferrous materials.

Key Features

• Thickness of 3/16 inch (0.1875 inch) for precise insert height control
• Supports boring bar and turning indexable tool holder applications
• Sold individually, minimum order quantity of 10 units

Compatibility

Designed for indexable boring bar and turning tool holders that accept diamond-shaped inserts with a 5/8 inch inscribed circle and ICSN-style shim seating in negative rake configurations.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before replacing or seating a shim, ensure the machine spindle is powered down and the tool holder is secured in a vise or fixture. Clean the shim pocket thoroughly before inserting to prevent seating errors that affect insert height and rake angle. Discard any shim showing deformation, cracking, or uneven wear, as a compromised shim will destabilize insert clamping.
