Kennametal 1875172 Lh Dwln Indexable Turning Toolholder

Product Description

The KENNAMETAL 1875172 is a left-hand DWLN-style indexable turning toolholder designed for negative rake turning operations on CNC lathes and manual turning centers. Part of the Kenclamp series, it accepts WN..43. series inserts secured by a top clamp holding method. The shank measures 1.25 inches wide by 1.25 inches tall with an overall length of 6 inches, providing a rigid platform for external turning applications. This toolholder is manufactured from steel and is intended for installation by machinists and CNC setup technicians in production and job-shop environments.

This toolholder is suited for external longitudinal turning and facing operations where left-hand cutting direction is required. The 5-degree lead angle and negative rake geometry support interrupted cuts and heavier feeds typical in steel and cast iron turning. The Kenclamp clamping system provides secure insert retention under the cutting forces associated with negative rake tooling. It is a single-use, non-coolant-through toolholder appropriate for dry or flood coolant applications from an external nozzle.
