Product Description

The SECO 75011666 is a shim screw designed for use with indexable cutting tools, specifically boring bars. It secures shims, anvils, and inserts within the toolholder pocket, maintaining precise seating and dimensional consistency during machining operations. This fastener corresponds to industry standard number 11666 and is sold individually, with a minimum order quantity of 10 units. Installation is performed by toolroom personnel, CNC machinists, and maintenance technicians working with indexable boring tool systems.

This shim screw is used in metalcutting applications where indexable boring bars are employed on CNC lathes, machining centers, and manual boring equipment. It is suited for production and job-shop environments where accurate insert positioning is critical to surface finish and dimensional tolerance. The part is compatible with specific insert geometries as noted in the compatibility section below.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before servicing toolholders or replacing shim screws. Use the appropriate Torx or hex key driver as specified by the toolholder manufacturer for the screw size. Do not overtighten, as shim screws in indexable toolholders are torqued to manufacturer-defined values found in the toolholder documentation.
