Kennametal 1021507 Indexable Insert Screw M5x0.8

Product Description

The KENNAMETAL 1021507 is a replacement clamping screw designed for indexable toolholder assemblies. It features an M5x0.8 thread and a 2 mm hex socket drive, providing secure insert retention in compatible toolholders and cartridges. This hardware is used to clamp cutting inserts in place during machining operations, maintaining precise positioning under cutting forces. Installation and replacement are performed by machinists and toolroom technicians during insert indexing or changeover. The small form factor and standardized thread make it a routine consumable in production and job-shop environments.

This screw is suited for use in turning, threading, and grooving toolholder assemblies that rely on mechanical clamping hardware. It is compatible with cartridge and clamp-style insert seats across the Kendex and Kenloc series. Applicable insert geometries include TP.. 110304 and TP.. 421 styles. Clamp compatibility includes the CKM34 clamp. This part is also identified under the CTFP toolholder style. It is sold individually but must be ordered in multiples of 10.
