Kennametal 1875155 Lh Dwln Indexable Turning Toolholder

Product Description

The KENNAMETAL 1875155 is a left-hand DWLN-style negative rake indexable turning toolholder designed for use on metalworking lathes and turning centers. Part of the Kenclamp series, it uses a clamp-style insert holding method to secure WN..43. series inserts with a 1/2-inch inscribed circle. The toolholder features a 5-degree lead angle and is machined from steel for rigidity under cutting loads. With a 1 x 1 inch square shank and a 5-inch overall length, it fits standard lathe tool blocks used in production and job-shop turning operations. Licensed machinists and CNC operators typically specify this holder for left-hand facing and turning passes.

This toolholder is suited for external turning applications in both production and job-shop environments. The left-hand orientation makes it appropriate for cuts requiring right-to-left tool travel or back-turning setups. The Kenclamp clamping system provides repeatable insert indexing without coolant-through capability, keeping the design straightforward for standard wet or dry turning operations. It accepts WN.. 432 compatible inserts per the manufacturer specification.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Power down and lock out the machine spindle before changing inserts or repositioning the toolholder in the tool block. Secure the shank firmly in the tool post to the machine manufacturer torque specification before initiating a cut. Inspect the clamp screw and insert seat for chips or wear at each insert change to maintain accurate tool geometry.
