Kennametal 1953181 Grooving Cutoff Toolholder Right Hand

Product Description

The KENNAMETAL 1953181 is an indexable grooving and cutoff toolholder designed for external turning operations on CNC lathes and turning centers. Built on the A4SM series platform, it accepts A4..03.. style inserts secured by a clamp-style insert holding method for repeatable edge positioning and rigid support under interrupted cuts. The toolholder is right-hand orientation with a square shank measuring 1 inch by 1 inch (25.4 by 25.4 mm) and an overall length of 6 inches (152.4 mm). It supports a minimum groove width of 0.118 inches (3 mm) and a maximum depth of cut of 0.67 inches (17 mm), making it suitable for moderate to deep grooving and full cutoff applications.

This toolholder is used in external grooving, parting, and cutoff operations on a range of workpiece materials in production turning environments. It is typically installed by machinists and CNC lathe operators in job shops, production facilities, and toolroom settings. The A4SM series is a proven platform for applications requiring consistent groove geometry, including O-ring grooves, snap-ring grooves, and standard cutoff work. No coolant-through capability is incorporated in this holder, so flood or mist coolant delivery via standard machine nozzles is the typical cooling method.

Installation Notes

Installation should be performed by a qualified machinist or CNC lathe operator. Power down and lock out the machine spindle before mounting or removing the toolholder from the turret or toolpost. Ensure the shank seating surfaces are clean and free of chips before tightening to prevent misalignment. Verify insert seating and clamp security before initiating any cutting cycle.
