Kennametal 1096144 Indexable Turning Toolholder MCMNN164D

Product Description

The KENNAMETAL 1096144 is an indexable turning toolholder in the MCMN style, designed to hold CN-series negative-rake inserts using a clamp and screw holding method. It belongs to Kennametal's Kenloc series, a line engineered for rigid, repeatable insert clamping on CNC and manual lathes. The toolholder features a neutral hand orientation, a 1 x 1 inch steel shank, and an overall length of 6 inches. The head length measures 1.39 inches, with a back-of-bar to cutting edge distance of 0.5 inches. Compatible with CN.. 432 inserts at a 0.5 inch inscribed circle. Coolant-through capability is not included. This holder is installed by machinists and toolroom technicians on turning centers and engine lathes performing external turning operations.

This toolholder is suited for external turning applications on CNC turning centers and conventional lathes where a neutral-hand setup is required. The MCMN style accommodates 80-degree diamond-shaped CN inserts, making it a common choice for general-purpose turning on steel, cast iron, and similar machinable materials. The 1 x 1 inch shank fits standard tool post and turret stations sized for that cross-section. It is appropriate for both roughing and finishing passes when paired with the correct CN.. 432 insert grade and geometry.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before mounting or removing the toolholder, confirm the machine is powered down, the spindle is locked, and the turret is in a safe index position. Use calibrated torque tools when tightening the clamp screw to the insert seat — follow the insert manufacturer's seating procedure for the CN.. 432 insert style. Inspect the insert pocket and seating surfaces for chips or wear before each insert change.
