Kennametal 1874862 Dcln Indexable Turning Toolholder

Product Description

The KENNAMETAL 1874862 is a right-hand DCLN-style negative rake indexable turning toolholder designed for precision external turning operations on CNC and manual lathes. Built on the Kenclamp insert holding system, it uses a clamp-style clamping method to secure CN..43 series inserts with an inscribed circle of 0.5 inches. The steel shank measures 1 inch wide by 1 inch high with an overall length of 6 inches, making it a compact, rigid platform for general-purpose and finish turning. Licensed machinists, CNC setup technicians, and tool-and-die professionals working in production or job-shop environments will find this holder a direct fit for standard toolpost and VDI setups.

This toolholder is suited for external longitudinal and facing operations where a 5-degree lead angle and negative rake geometry are preferred. Negative rake inserts typically handle harder workpiece materials and interrupted cuts well, delivering longer edge life under heavy-duty conditions. The 1874862 is appropriate for steel, cast iron, and similar ferrous materials in both high-volume production turning cells and manual turning applications. No coolant-through capability is present, so flood or mist coolant delivery must be routed externally if required by the application.

Installation Notes

Installation is typically performed by a machinist or CNC setup technician. Secure the toolholder in the toolpost or turret to the machine manufacturer's clamping torque specification before operation. Ensure the machine spindle is fully stopped and all energy is locked out before changing inserts or repositioning the holder. Do not exceed the insert manufacturer's recommended depth of cut or feed rate for the selected CN..43 series insert grade.
