Kennametal 2273004 Dckn Turning Toolholder 1x1 Shank

Product Description

The KENNAMETAL 2273004 is a right-hand DCKN-style indexable turning toolholder designed for negative rake metal cutting operations on CNC and manual lathes. Part of the Kennametal Kenclamp series, it accepts CN..42. style inserts secured by a clamp-style insert holding method. The shank measures 1 inch wide by 1 inch tall with an overall length of 6 inches, making it a standard 1-inch square shank toolholder suited for medium-duty turning applications. Toolholder body is constructed from steel for rigidity and long service life under interrupted and continuous cut conditions. This holder does not include coolant-through capability.

The 2273004 is intended for use in turning centers, engine lathes, and turret lathes where a right-hand 1-inch square shank toolholder is required. The 15-degree lead angle geometry of the DCKN style is well suited for facing, turning, and light profiling operations on ferrous and non-ferrous materials. It is installed by machinists and CNC setup technicians in job shops, production machining environments, and maintenance machine shops. The head length is 1.25 inches, providing consistent tool overhang geometry for repeatable depth-of-cut setups.
