Product Description

The KENNAMETAL 5939459 is a right-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 EG0400M04P04 inserts secured by a clamp-style insert holding method. The toolholder delivers a maximum depth of cut of 0.866 inches and accommodates workpieces up to 1.732 inches in diameter. The shank measures 0.75 inches in both height and width, with an overall length of 4.5 inches. Coolant-through capability is included, supporting chip evacuation and tool life in production turning environments. This toolholder is intended for use by machinists and CNC operators performing precision cutoff and grooving work.

The 5939459 is suited for production and job-shop turning applications where consistent, repeatable cutoff performance is required. Its compact shank profile fits standard rectangular tool stations on most CNC turning centers. The clamp-style insert retention provides rigid support during interrupted cuts and high-feed parting operations. Compatible insert size code EG0400M04P04 is specific to the Beyond Evolution series and should be confirmed against the machine tool station configuration before ordering. This toolholder is appropriate for both ferrous and non-ferrous workpiece materials depending on the insert grade selected.
