Kennametal 1875148 Ddjn Indexable Turning Toolholder

Product Description

The KENNAMETAL 1875148 is a right-hand DDJN-style indexable turning toolholder designed for external turning operations on metal lathes and CNC turning centers. Part of the Kenclamp series, it uses a clamp-style insert holding method with a negative rake geometry to deliver controlled cutting action on ferrous and non-ferrous materials. The shank measures 1.25 inches wide by 1.25 inches tall, and the overall length is 6 inches. This toolholder accepts DN..43. series inserts with a 0.50 inch inscribed circle. It is intended for installation by machinists and CNC tooling technicians in production and job-shop turning environments.

The 1875148 is suited for external turning applications in both manual lathe and CNC turning center setups where a right-hand DDJN configuration is required. The negative rake insert geometry makes it appropriate for interrupted cuts and harder workpiece materials where edge strength is a priority. The Kenclamp clamping system provides rigid insert seating, which supports consistent tool life and repeatable cutting performance across production runs. No coolant-through capability is included, making it best matched to flood or dry coolant strategies.

Installation Notes

This toolholder is installed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the turret or tool post is locked out before changing toolholders or inserts. Use calibrated torque wrenches and appropriate Kennametal Kenclamp hardware when seating the clamping screw to avoid insert movement or clamping-system damage. Confirm tool centerline height alignment to spindle centerline per machine manufacturer specifications before running the first part.
