Kennametal 1096344 Mtjn Indexable Turning Toolholder

Product Description

The KENNAMETAL 1096344 is a left-hand MTJN-style indexable turning toolholder designed for negative-rake metal cutting operations on CNC and manual lathes. Built on the Kenloc platform, it accepts TN..43. series inserts and secures them with a clamp-and-screw holding method for rigid, repeatable positioning under heavy interrupted or continuous cuts. The shank measures 0.75 inches wide by 0.75 inches tall with an overall length of 4.5 inches. Steel construction provides the toughness required for high-stock-removal turning applications. This toolholder is installed by machinists and CNC setup technicians in production and job-shop environments.

The 1096344 is suited for external turning operations where a left-hand tool path is required, such as turning toward the tailstock or machining to a shoulder from the right side of the part. The 3-degree lead angle and 0.5-inch insert inscribed circle support a broad range of turning passes on steel, cast iron, and similar ferrous workpieces. It is commonly used in turret-style tool blocks on engine lathes and CNC turning centers. Coolant-through capability is not included in this holder.

Key Features

• Left-hand MTJN holder style for right-to-left cutting direction
• Kenloc clamp-and-screw insert retention for secure seating under load
• Accepts TN..43. series inserts with 0.5-inch inscribed circle
• Negative rake geometry reduces cutting forces on rigid setups
• Steel shank construction for durability in production turning
• 3-degree lead angle with 1.0-inch back-of-bar to cutting edge clearance

Compatibility

Designed for use with TN..43. series inserts, specifically the TN.. 432 insert family. Fits standard square-shank tool blocks and turret stations accepting a 0.75-inch by 0.75-inch shank profile.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the lathe spindle is fully stopped and the machine is in a locked-out, de-energized state before changing toolholders or inserts. Seat the shank fully in the tool block and torque the clamping screws to the tool block manufacturer specifications. Verify insert seating and edge condition before resuming cutting operations.
