Sumitomo 2G52141 Indexable Milling Shim Seat Wgcs

Product Description

The SUMITOMO 2G52141 is a WGCS-style shim seat designed for indexable milling toolholders. It sits beneath the cutting insert in the pocket of the toolholder body, providing a hardened, dimensionally precise seating surface that protects the toolholder from insert-related impact and wear. The shim measures 0.6555 inches thick and is compatible with square inserts having a 1/2 inch (0.5000 inch) inscribed circle. Designed for right-hand cutting direction, this shim is matched to WaveMill WGC and WGX series toolholder platforms. Machinists and tooling technicians working in production milling environments rely on accurate shim geometry to maintain consistent insert indexing and cutting performance.

This shim seat is intended for use in indexable milling applications where WaveMill WGC or WGX series toolholders are in service. It is a direct replacement component used during routine toolholder maintenance or after insert pocket damage. Suitable for both shop floor maintenance and toolroom reconditioning work, the 2G52141 supports right-hand milling operations with square inserts at a 1/2 inch inscribed circle size.

Installation Notes

Shim seat replacement is typically performed by a machinist or toolroom technician during toolholder maintenance. Remove the insert and any clamping hardware before extracting the worn shim. Ensure the insert pocket is clean and free of chips or debris before seating the new shim. Verify correct shim orientation for right-hand cutting direction before reinstalling the insert and clamp screw to the toolholder manufacturer's specified procedure.
