Kennametal 2504009 Left Hand Dvon Turning Toolholder

Product Description

The KENNAMETAL 2504009 is a left-hand DVON-style indexable turning toolholder built for negative rake machining operations. Part of the Kennametal Kenclamp series, it accepts VN..33 series inserts secured by a clamp-style insert holding method. The toolholder features a 1 inch by 1 inch steel shank with an overall length of 6 inches and a head length of 1.47 inches. With a rake angle of -6.4 degrees and a 17.5-degree lead angle, this holder is suited for turning applications where controlled chip formation and edge stability are priorities. Installed by CNC machinists and toolroom technicians, it is a purpose-built OEM-style component for production and job shop turning centers.

This toolholder is designed for use on manual and CNC turning lathes in both production and job shop environments. The left-hand orientation suits specific tool post positions and turning directions, typically used for back-turning or specific finishing pass configurations. The Kenclamp insert retention system provides secure clamping of VN..33 compatible inserts, with the insert inscribed circle measuring 0.375 inches (3/8 inch). No coolant-through capability is present on this holder, so external coolant delivery should be planned accordingly during setup.
