Kennametal 5979184 Modular Cutoff Cutting Unit Head

Product Description

The KENNAMETAL 5979184 is a modular cutoff cutting unit head designed for precision parting and grooving operations on CNC lathes and turning centers. Part of the Beyond Evolution series, this right-hand unit head accepts A2, A3, and A4 inserts and delivers a maximum cutting depth of 32mm and a maximum width of cut of 4mm (0.158 inches). The head length measures 67.75mm with a center-to-cutting-edge distance of 9.93mm. At 0.053 pounds, it is a compact, lightweight component suited for high-productivity cutoff applications. Installation and insert changes are handled by machinists and tooling technicians working with modular tooling systems.

This cutting unit head is intended for use in modular cutoff and grooving tooling systems where repeatable positioning and quick head changes are required. It is well suited to production turning environments handling medium-depth parting cuts on bar stock, tubing, and turned components. The right-hand cutting orientation makes it compatible with standard spindle-forward turning operations. Compatible insert grades within the A2, A3, and A4 designation allow selection based on workpiece material and cutting conditions.

Installation Notes

Installation is performed by qualified machinists or tooling technicians familiar with modular turning tooling systems. Power down and lock out the machine spindle before removing or installing any cutting unit head. Follow the toolholder manufacturer torque and seating requirements for the Beyond Evolution modular interface to ensure proper clamping and repeatability. Verify insert grade and geometry selection against the workpiece material before resuming cutting operations.
