Kennametal 1095808 Proon Turning Toolholder RC..64

Product Description

The KENNAMETAL 1095808 is a neutral-rake PROON-style indexable turning toolholder designed for precision lathe work in metalworking and machining environments. Built with a 1.5 x 1.5 inch square shank and an overall length of 8 inches, this toolholder accepts RC..64 series inserts secured via a pin-clamp holding method. The screw-on series design delivers consistent insert seating and repeatable cutting geometry. At 4.4 pounds, the steel construction provides rigidity under interrupted cuts and continuous turning operations. Licensed machinists and CNC lathe operators working in job shops or production machining facilities are the primary installers and users.

This toolholder is suited for external turning applications on manual engine lathes and CNC turning centers where a neutral hand orientation is required. The neutral rake geometry makes it appropriate for both right-hand and center-line cutting approaches, particularly useful on multi-tool setups or symmetric workpiece configurations. The 3/4 inch (0.75 inch) insert inscribed circle accommodates larger RC..64 inserts, supporting heavier depths of cut and broader material removal rates in steel, cast iron, and similar ferrous workpieces.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before changing inserts or repositioning the toolholder in the turret or tool post. Use appropriate insert installation tools as specified for the pin-clamp holding method to avoid damaging the insert seat or locating pin. Verify shank clamping torque using the machine tool manufacturer guidelines, not assumed values.
