Kennametal 1096070 Mcln Turning Toolholder 1x1 Shank

Product Description

The KENNAMETAL 1096070 is a right-hand MCLN-style indexable turning toolholder built for negative rake CN..43 series inserts. It features a 1 inch by 1 inch square shank and an overall length of 6 inches, making it a standard fit for most CNC and manual lathe toolposts in that size class. The Kenloc clamping system secures the insert using a combination clamp-and-screw method, providing rigid holding under interrupted and continuous turning operations. This toolholder is manufactured from steel and does not include coolant-through capability. It is installed by machinists and CNC lathe operators in job shop, production, and toolroom environments.

The 1096070 is suited for external turning applications where a 5-degree lead angle is required. The head length measures 1.2 inches and the back-of-bar to cutting edge distance is 1.25 inches, allowing consistent tool height setup. It accepts CN..43 series inserts with a 0.5 inch inscribed circle diameter, which is a widely available insert geometry. This toolholder is appropriate for use on steel, cast iron, and similar workpiece materials common to general-purpose turning operations on both manual and CNC lathes.
