Kennametal 1020647 Kenloc Ckm Indexable Clamp

Product Description

The KENNAMETAL 1020647 is a Kenloc series CKM-style clamp designed to secure indexable inserts in compatible turning toolholders. It is built for neutral-cut applications and works with STCM11 clamp screws. The clamp is a precision clamping component used in CNC and manual lathe setups where consistent insert seating and repeatable positioning are critical. Weighing 0.0119 pounds, it is a compact, lightweight component intended for toolholder maintenance and insert changeout routines. Machinists and toolroom technicians working with KM40-series Kennametal toolholders will find this clamp is the correct OEM-style replacement or spare clamping element for keeping those systems in service.

The 1020647 is suited for turning operations on CNC lathes and machining centers using KM40-series modular toolholders. It is intended for neutral cutting direction setups, meaning the toolholder accepts both left-hand and right-hand insert orientations depending on configuration. Compatible toolholders include KM40MDJNL1504, KM40MDJNL1506, KM40MDJNR1504, KM40MDJNR1506, KM40MDQNL1504, KM40MDQNL1506, KM40MDQNR1504, KM40MDQNR1506, KM40MTGNL22, and KM40MTGNR22. This clamp is sold in a package quantity of 1 with a minimum order quantity of 5 units.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians during insert changeout or toolholder maintenance. Power down and lock out the machine spindle before servicing any toolholder component. Use the correct STCM11 clamp screw and appropriate torque driver per the toolholder manufacturer service documentation — do not substitute incompatible screw styles, as improper clamping force can cause insert movement under cut. Inspect the clamp seat and screw threads for wear or damage before reinstalling.
