Kennametal 1095982 Mrgn Left Hand Turning Toolholder

Product Description

The KENNAMETAL 1095982 is a left-hand MRGN-style indexable turning toolholder designed for negative rake metal-cutting operations on CNC and manual lathes. Built on the Kenloc clamping platform, it secures RN..64 series round inserts using a combination clamp and screw holding method, providing rigid, repeatable insert location. The steel shank measures 1 inch wide by 1 inch tall with an overall length of 6 inches, making it a standard square-shank toolholder suited to most 1-inch tool post or turret positions. The 15-degree lead angle and -5-degree rake angle geometry are set for general-purpose external turning where stable chip control and tool life are priorities.

This toolholder is intended for use in production and job-shop turning operations on ferrous and non-ferrous workpieces. It is installed by machinists and toolroom technicians in CNC turning centers, engine lathes, and turret lathes equipped to accept 1 x 1 inch square-shank tooling. The left-hand orientation suits applications where the tool feeds from left to right relative to the spindle, or where back-turning and facing from a rear turret position is required.

Key Features

• Left-hand MRGN toolholder style with 15-degree lead angle for external turning
• Kenloc clamp-and-screw insert holding method for rigid, positive insert retention
• Accepts RN..64 series round indexable inserts with 0.75-inch inscribed circle diameter

Compatibility

Designed to accept RN..64 series round indexable inserts as specified by Kennametal. Verify insert pocket dimensions and clamping hardware against the RN..64 insert specification before ordering replacement inserts.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing the toolholder or insert. Torque the insert clamp screw per the insert manufacturer's seating procedure using the appropriate Torx or hex key. Confirm tool centerline height and lead angle orientation before taking a first cut.
