Kennametal 1803445 Indexable Cutoff Toolholder Left Hand

Product Description

The KENNAMETAL 1803445 is a left-hand indexable cutoff toolholder designed for parting and grooving operations on CNC lathes and turning centers. It accepts A2030 series inserts secured by a screw-clamp holding method, providing rigid insert retention during cut-off passes. The toolholder has a maximum depth of cut of 1.024 inches (26 mm) and accommodates workpiece diameters up to 2.44 inches. The 1 x 1 inch square shank interfaces with standard turning center toolposts and quick-change systems. Machinists and CNC lathe operators working in production or job-shop environments install this holder for consistent, repeatable cutoff performance.

This toolholder is suited for residential and commercial machine shops running turning operations on bar stock or chucked workpieces up to 2.44 inches in diameter. The A3 series design targets applications requiring a left-hand approach angle, typical in gang-tooling setups or specific spindle-direction configurations. The 6-inch overall length and 1.67-inch head length position the insert at the correct geometry for straight cutoff work. It is appropriate for use with ferrous and non-ferrous materials when paired with compatible A2030 inserts.
