Kennametal 5980916 Grooving Cutoff Toolholder Right Hand

Product Description

The KENNAMETAL 5980916 is an external, right-hand indexable grooving and cutoff toolholder in the Beyond Evolution EVSC-T series. It accepts EG0300M03P02 inserts held by a clamp-style insert holding method, delivering a fixed groove width of 3 mm (0.118 inches) and a maximum depth of cut of 26 mm (1.024 inches). The toolholder features through-coolant capability, supporting higher cutting speeds and longer insert life in demanding grooving and parting operations. It is designed for CNC lathe applications where precise groove geometry and secure insert seating are required. Machinists and CNC operators working in production turning environments are the primary installers of this toolholder.

This toolholder is suited for external grooving and cutoff operations on CNC turning centers and manual lathes equipped with a 1-inch square shank tool post or turret station. The EVSC-T style head geometry is intended for applications requiring consistent groove width control in steel, stainless, cast iron, and similar workpiece materials. The through-coolant port makes it well suited for deep grooving passes where chip evacuation and heat management are critical. Mount size 1616 confirms compatibility with standard 16 mm x 16 mm turret pocket configurations.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician with the machine fully powered down, spindle locked, and turret in a safe service position. Torque the toolholder clamp screws and turret mounting fasteners according to the machine tool manufacturer specifications. Verify through-coolant port alignment with the turret coolant supply before operation. Confirm insert seating and edge condition before initiating any cutting cycle.
