Kennametal 1116889 Ckm Clamp Indexables Top Notch

Product Description

The KENNAMETAL 1116889 is a CKM-style clamp designed for use with indexable insert toolholders in the Top Notch series. It secures indexable cutting inserts in place during turning and grooving operations, providing the clamping force needed to maintain insert position under cutting loads. The clamp is compatible with STCM38 clamp screws and is intended for professional installation by machinists and toolroom technicians working with precision turning toolholders. At 0.0068 pounds, it is a lightweight precision component engineered for repeatable insert seating.

This clamp is used in CNC turning and manual lathe applications where Top Notch series toolholders are specified. It is suited for production and job-shop environments requiring consistent insert clamping across multiple tool changes. The clamp fits toolholders in the Top Notch series, including the CTFPR 10CA11 complete toolholder, making it a direct-fit service replacement or spare component for shops running compatible toolholder setups.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and de-energize the machine spindle before servicing any toolholder clamp or insert. Use the specified STCM38 clamp screw when assembling this clamp to the toolholder to ensure correct clamping geometry. Do not substitute non-specified clamp screws, as improper hardware can result in insert movement or ejection during cutting.
