Kennametal 1018533 Top Notch Cm Clamp Indexable

Product Description

The KENNAMETAL 1018533 is a CM-style clamp designed for use with the Top Notch series of indexable tooling systems. It secures indexable inserts in neutral cut tool holders, maintaining consistent insert positioning during turning and profiling operations. Weighing 0.022 pounds, this clamp is a small but precision-critical component that affects insert stability and surface finish quality. Licensed machinists, CNC programmers, and toolroom technicians rely on clamps like this to maintain repeatable cutting geometry across production runs. Proper clamping force is essential for preventing insert movement under cutting loads.

This clamp is intended for use in the Kennametal Top Notch indexable insert clamping system, commonly found on OD turning, facing, and profiling tool holders used in production and job shop environments. The neutral cut orientation makes it suitable for balanced cutting applications where feed direction flexibility is required. It is installed on tool holders mounted to CNC lathes, manual engine lathes, and turret tooling blocks in both light and moderate-duty material removal applications.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine spindle stopped and all axes at rest. Remove the worn or damaged clamp using the appropriate Kennametal Top Notch clamp screw driver or hex key as specified by the tool holder documentation. Seat the new clamp fully before torquing the clamping screw to ensure the insert is properly located against the pocket walls and bottom. Inspect the insert pocket and locating pin for wear before reinstalling any new insert.
