Kennametal 1095981 Mrgn Turning Toolholder 1x1 Shank

Product Description

The KENNAMETAL 1095981 is a right-hand MRGN-style indexable turning toolholder designed for negative-rake external turning operations on CNC and manual lathes. Built on the Kenloc clamping platform, it uses a clamp-and-screw insert holding method to secure RN..64 series round inserts with a 3/4-inch inscribed circle. The steel shank measures 1 inch wide by 1 inch tall with an overall length of 6 inches, and the rake angle is set at -5 degrees. It is installed by machinists and toolroom technicians in production turning applications requiring stable, repeatable insert indexing.

This toolholder is suited for external turning on ferrous and non-ferrous workpieces in both production shop and job-shop environments. The MRGN style with a 15-degree lead angle is commonly used for straight turning and light facing passes where a round insert provides maximum edge count and insert life. The Kenloc clamping system is a Kennametal-series platform found on a wide range of production lathe setups. Coolant-through capability is not included on this holder.
