Kennametal 5939465 Indexable Cutoff Toolholder Left Hand

Product Description

The KENNAMETAL 5939465 is a left-hand indexable cutoff toolholder designed for parting and grooving operations on CNC lathes and turning centers. Built to the Beyond Evolution series standard, it accepts EG0300M03P02 inserts secured by a clamp-style insert holding method. Maximum depth of cut is 0.866 inches, and maximum workpiece diameter is 1.732 inches. The shank measures 0.75 inches in height and 0.75 inches in width, with an overall length of 4.5 inches. Coolant-through capability is built in, supporting high-pressure coolant delivery directly to the cutting zone. This toolholder is installed by machinists and CNC setup technicians working in production turning environments.

The 5939465 fits standard square-shank tool blocks and turrets common to CNC turning centers handling small- to medium-diameter workpieces up to 1.732 inches. Its left-hand orientation suits front-tool-post configurations and specific turret station assignments. The Beyond Evolution series is engineered for consistent insert indexing and rigid clamping, making it appropriate for both interrupted-cut parting and continuous-groove applications in steel, stainless, and similar materials.

Key Features

Compatibility

Designed for use with EG0300M03P02 inserts (complete insert compatibility code EG0300M03P02, insert seat size 3). Fits standard 0.75 inch square-shank tool blocks and turrets on CNC turning centers accepting the EVSM-style Beyond Evolution toolholder system.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before mounting or removing the toolholder from the turret. Verify turret station orientation and confirm left-hand designation matches the intended cutting direction before securing. When connecting coolant-through supply lines, ensure system pressure is within the machine tool specification before resuming operation.
