Kennametal 1099381 Cm Clamp Indexables Right Hand Top Notch

Product Description

The KENNAMETAL 1099381 is a CM-style clamp designed for indexable insert toolholders in the Top Notch series. It secures indexable inserts during turning and grooving operations, maintaining precise insert positioning under cutting loads. The clamp is configured for right-hand cutting direction and is compatible with S310 clamp screws. Weighing approximately 0.0066 pounds, this compact component is a direct-fit replacement or spare for Top Notch series toolholders. Installation and replacement are performed by machinists and toolroom technicians as part of routine insert maintenance on CNC lathes and manual turning centers.

This clamp is suited for use in metal-cutting environments where Top Notch series indexable toolholders are in service. The right-hand cutting configuration makes it appropriate for standard OD turning and grooving setups. Confirmed compatible toolholder models include NASR-062D and NASR-082D. It is a component-level part sold individually, intended for shops that maintain spare clamp inventory to minimize downtime during insert changes.
