Kennametal 1875137 Dcln Indexable Turning Toolholder

Product Description

The KENNAMETAL 1875137 is a right-hand DCLN-style indexable turning toolholder in the Kenclamp series, designed for negative-rake single-point turning operations on CNC and manual lathes. Built from steel, it accepts CN..43. style inserts and uses a clamp-style insert holding method for secure, repeatable cutting edge positioning. The shank measures 0.75 inches wide by 0.75 inches tall, with an overall length of 4.5 inches. A 5-degree lead angle and 1.0-inch back-of-bar to cutting edge dimension make this toolholder suited for external turning and facing in production environments. Installation requires no coolant-through capability.

This toolholder is used in external turning and facing operations on ferrous and non-ferrous workpieces in both job shop and production machining environments. It is sized for standard tool turrets and toolpost holders that accept 3/4-inch square shank toolholders. Machinists and CNC operators running roughing or finishing passes with CN..43. style inserts will find this holder directly applicable. The Kenclamp clamping system provides firm insert retention under interrupted cuts and moderate to heavy chip loads.
