Kennametal 1097570 Threading Toolholder External Right Hand

Product Description

The KENNAMETAL 1097570 is an external, right-hand indexable threading toolholder from the Top Notch series, designed for precision threading and grooving operations on CNC lathes and turning centers. Built on a 1 inch square shank (25.4 x 25.4 mm) with an overall length of 6 inches, this toolholder accepts N.4L insert geometry and uses a clamp-style insert holding method. The NE toolholder style positions the cutting edge for right-hand external thread forms. With a maximum depth of cut of 0.294 inches and a head length of 0.75 inches, it delivers the rigidity and repeatability that production machinists and toolroom operators require.

This toolholder is suited for external threading and grooving applications in production turning environments, including job shops, aerospace, and general metalworking operations. The Top Notch series is recognized for consistent insert seating and secure clamping, making it a reliable choice for high-volume thread-turning passes on ferrous and non-ferrous workpieces. Licensed machinists and CNC operators running repetitive threading cycles will find the geometry and insert compatibility straightforward to set up and maintain.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolsetter. Secure the shank firmly in the tool turret or tool block according to the machine manufacturer torque and clamping specifications before powering the spindle. Ensure the cutting edge height is set on centerline with the workpiece axis prior to taking threading passes. Always index or replace the insert with the machine in a safe, powered-down state and the turret locked out.
