Kennametal 1096316 Indexable Turning Toolholder MRGNL206D

Product Description

The KENNAMETAL 1096316 is a left-hand indexable turning toolholder in the Kenloc series, designed for use with RN-style negative-rake inserts on CNC and manual lathes. It uses a clamp screw insert holding method and features a 1.25 x 1.25 inch square steel shank with an overall length of 6 inches. The toolholder is engineered for a negative rake angle of -5 degrees, making it well-suited for interrupted cuts and hard-turning applications where insert stability is critical. Licensed machinists and CNC turning specialists are the primary installers of this toolholder.

This toolholder is appropriate for external turning operations in production and job-shop environments, both at the manual lathe and CNC turning center level. It is configured for left-hand cutting direction, which determines proper orientation on the machine turret or tool post. The MRGNL206D style designation identifies the toolholder geometry, and the RN insert compatibility supports a 3/4-inch inscribed circle insert, providing a robust cutting edge for medium to heavy material removal rates. No coolant-through capability is present on this toolholder.
