The SECO 00018742 is a lock screw designed to secure indexable inserts in compatible turning toolholders. It features a T10 Torx drive with M3.5 thread and an overall length of 7.50 millimeters. This screw is used to clamp cutting inserts firmly in place during turning operations, preventing movement under cutting loads. Installation requires a TX3.5 key driver. The screw is compatible with SRGC-style toolholders and is sold in a minimum order quantity of 10 units per transaction, with a package quantity of 1 per unit. At 0.02 pounds, it is a lightweight but critical fastener in any precision turning setup.
This lock screw is intended for use in CNC and manual turning applications where indexable insert toolholders of the SRGC style are employed. It is a replacement-grade component suited for maintenance of toolholder assemblies on production floors, job shops, and machine shops running turning operations. The screw interfaces directly with RCMT 32.5 inserts, making it a precise fit for those tooling configurations. Machinists and tooling technicians responsible for insert changeovers and toolholder maintenance are the primary installers of this component.
Compatible with SRGC-style toolholders using RCMT 32.5 indexable inserts. Requires a TX3.5 key driver for installation and removal.
This screw is installed and serviced by machinists or tooling technicians during indexable insert changeovers. Power down and secure the machine spindle before accessing the toolholder. Use only a TX3.5 Torx key driver to avoid stripping the drive recess. Do not substitute thread sizes or drive types, as improper fasteners can cause insert movement during cutting and create a safety hazard.
