Kennametal 1875135 Lh Dcln Indexable Turning Toolholder

Product Description

The KENNAMETAL 1875135 is a left-hand DCLN-style indexable turning toolholder designed for negative-rake external turning operations on CNC lathes and manual turning centers. Built on the Kenclamp series platform, it features a 1 inch x 1 inch square steel shank and an overall length of 5 inches, with a head length of 1.25 inches. The clamp-style insert holding method provides rigid, repeatable seating for CN..43. style inserts with a 0.5 inch inscribed circle. This toolholder is installed and set up by machinists and CNC turning specialists in production and job-shop environments.

The 1875135 is suited for external longitudinal turning and facing operations where a left-hand approach angle is required. The 5-degree lead angle promotes chip flow and surface finish consistency on steel, cast iron, and similar workpiece materials. The Kenclamp clamping system accommodates CN..43. series inserts, specifically the CN.. 432 family, offering broad cutting geometry options within a single holder body. This toolholder is appropriate for both light-duty finishing and moderate roughing cuts within its shank size class.
