Kennametal 1016454 Mdjn Rh Indexable Turning Toolholder

Product Description

The KENNAMETAL 1016454 is a right-hand MDJN-style indexable turning toolholder built for negative-rake insert geometries in general turning operations. It features a 1-1/4 inch square shank with an overall length of 6 inches and accepts DN..43. series inserts held by a clamp-and-screw method. Manufactured from steel and belonging to KENNAMETALs Kenloc series, this toolholder is designed for stable, repeatable insert positioning on manual and CNC lathes. It is suited for machinists and tooling specialists who require consistent performance on external turning applications.

This toolholder is intended for external turning operations on metalworking lathes in both production and job-shop environments. The Kenloc series is a KENNAMETAL platform commonly used in industrial machining settings where negative-rake DN-style inserts are the standard. The 3-degree lead angle geometry suits straight turning and light facing passes. Coolant-through capability is not included in this configuration, making it appropriate for conventional flood or dry cutting setups.

Key Features

• Right-hand cutting orientation for standard external turning setups
• Accepts DN..43. series inserts with a 1/2 inch inscribed circle
• Clamp-and-screw insert retention for secure, repeatable seating
• Negative rake geometry compatible with DN..43. insert family
• Steel construction for rigidity under interrupted and continuous cuts
• No coolant-through ports — suited for flood or dry machining environments

Compatibility

Designed to accept DN..43. series negative-rake indexable inserts with a 1/2 inch inscribed circle. Complete insert compatibility designation is DN.. 432. This toolholder is part of the KENNAMETAL Kenloc series platform.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with indexable toolholder setups on CNC or manual turning centers. Ensure the machine spindle is fully stopped and all power is locked out before mounting or removing the toolholder. Secure the shank in the turret or tool block to the machine manufacturers specified clamping torque using appropriate tooling hardware. Follow insert manufacturer guidelines when seating and torquing the clamp screw to avoid insert damage or improper seating.
