Kennametal 3641594 Indexable Turning Toolholder

Product Description

The KENNAMETAL 3641594 is a CRDPN203DV-style indexable turning toolholder designed for use with clamp-style insert retention on CNC lathes and manual turning centers. It features a neutral hand orientation and a 1.25 x 1.25 inch square shank with an overall length of 6 inches. The V-Bottom Round series design positions the cutting edge 0.621 inches back from the bar, providing a stable platform for round insert indexing. This toolholder is installed by machinists and toolroom technicians working with indexable carbide inserts in production turning applications.

This toolholder is suited for external turning operations on CNC and conventional lathes in both job shop and production environments. The neutral rake angle and CRDP toolholder style accommodate a range of round insert geometries. The clamp holding method allows quick insert changes without disturbing the toolholder setup, reducing downtime during runs. It is appropriate for both roughing and finishing passes depending on the insert selected.
