Kennametal 1806715 Indexable Cutoff Toolholder Left Hand

Product Description

The KENNAMETAL 1806715 is a left-hand indexable cutoff toolholder designed for parting and grooving operations on CNC lathes and turning centers. Built to the A3 series standard, it accepts A2016 inserts secured by a screw-clamp holding method, providing rigid, repeatable insert positioning. The toolholder features a 0.5 inch square shank (0.5 inch height by 0.5 inch width) and an overall length of 5 inches. Maximum depth of cut is 0.3937 inches, and it handles workpieces up to 0.79 inches in diameter. Machinists and toolroom technicians working with small-diameter bar stock on manual or CNC lathes will find this holder a direct, catalog-matched solution.

This toolholder is suited for light-duty cutoff and grooving work on small-diameter workpieces in production turning environments. The left-hand orientation positions the cutting edge for specific spindle rotation and approach directions common in gang-tooling setups or tail-stock-side operations. The A3SC toolholder style and insert seat size 1 make it compatible with the A2016 insert family, allowing access to the full range of Kennametal grade and geometry options for that insert series. Typical applications include parting off turned components and cutting shallow grooves on ferrous and non-ferrous stock.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine powered down and the spindle locked before changing or adjusting the toolholder. Verify that the shank bore or turret pocket matches the 0.5 inch by 0.5 inch shank dimensions before mounting. Secure all clamp screws to the toolholder manufacturer's recommended procedure and confirm insert seating before resuming cutting operations. Do not exceed the stated maximum depth of cut or workpiece diameter limits.
