Kennametal 2504008 Indexable Turning Toolholder DVONR163DKC3

Product Description

The KENNAMETAL 2504008 is a DVON-style indexable turning toolholder designed for negative-rake external turning operations on CNC lathes and turning centers. It uses a clamp-style insert holding method with a rake angle of -6.4 degrees, accepting VN-style inserts with a 3/8-inch (0.375-inch) inscribed circle. The shank measures 1 inch wide by 1 inch tall, with an overall length of 6 inches. Built from steel under the Kennametal Kenclamp series, this toolholder is intended for right-hand cutting and is installed by machinists and toolroom technicians running precision turning applications.

This toolholder fits standard 1x1 inch shank pockets common to most production and job-shop CNC lathes. It is suited for external turning passes requiring a negative-rake geometry, which provides added edge strength when machining harder materials or taking heavier cuts. The DVON style positions the insert for a lead angle and side clearance combination typical of general-purpose longitudinal turning. Compatible insert style is VN.. 332, making toolholder-to-insert selection straightforward when ordering replacements or building out a tool crib.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and lock out the machine spindle before changing or seating the toolholder in the turret. Ensure the tool block or holder pocket is clean and free of chips before seating to maintain centerline accuracy. Follow the machine manufacturer's torque and clamping specifications for the turret or tool post; do not substitute generic fastener values.
