Kennametal 1094617 Turning Toolholder Svjbr 0.5in Shank

Product Description

The KENNAMETAL 1094617 is a screw-clamp indexable turning toolholder in the SVJBR style, designed for external turning operations on CNC lathes and manual turning centers. It accepts VB-style inserts with a 0.25-inch inscribed circle and uses a screw-on clamping method to hold the insert securely at a neutral rake angle of 0 degrees. The shank measures 0.5 x 0.5 inches with an overall length of 6 inches, making it suited for standard tool post and quick-change setups. The toolholder is right-hand oriented and built from steel for durability in production turning environments. Machinists and CNC programmers specify this holder when running VB.. 221 inserts on external diameter profiles.

This toolholder is intended for external turning applications in both production and job-shop settings. It fits standard 0.5-inch square tool post slots and is commonly mounted in quick-change or gang-style turrets on CNC turning centers. The neutral rake geometry and screw clamping make it appropriate for finishing and light roughing passes where positive insert retention and repeatable edge presentation are required. No coolant-through capability is present, so external flood or mist coolant delivery applies.

Key Features

• SVJBR toolholder style with right-hand cutting orientation
• Screw-on insert clamping for positive retention and quick index changes
• Accepts VB.. 221 inserts with 0.25-inch inscribed circle
• Neutral rake, 0-degree rake angle for versatile turning profiles
• Steel construction for rigidity and wear resistance in turning operations
• 0.5-inch back-of-bar to cutting edge dimension for consistent tool reach

Compatibility

Designed for use with VB.. 221 series indexable inserts with a 0.25-inch inscribed circle. Compatible with standard 0.5 x 0.5-inch square-shank tool posts and CNC lathe turret pockets of the same size. No specific machine model compatibility data was provided in the product input.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Ensure the lathe is powered down and the spindle is locked before mounting or adjusting the toolholder. Torque the insert-clamping screw to the insert manufacturer's recommendation using the appropriate Torx or hex key — do not overtighten, as this can crack the insert. Verify tool centerline height against the workpiece spindle centerline before initiating a cut.
