Kennametal 2273016 Ddjn Indexable Turning Toolholder

Product Description

The KENNAMETAL 2273016 is a right-hand DDJN-style negative rake indexable turning toolholder from the Kenclamp series. It accepts DN..33. style inserts secured by a top clamp holding method. The shank measures 1 inch wide by 1 inch tall, with an overall length of 6 inches and a head length of 1.25 inches. The back-of-bar to cutting edge distance is 1.25 inches. The toolholder body is constructed from steel and is designed for use on CNC lathes and manual turning centers. This tool is installed and set up by machinists and toolroom technicians performing OD turning operations requiring a negative rake geometry.

This toolholder is suited for external turning applications on lathes where a right-hand cutting direction is required. The DDJN style provides a 3-degree lead angle, which positions the insert for general-purpose OD turning. It is commonly used in production shops and job shops running steel, stainless, and cast iron workpieces. The Kenclamp clamping system holds the insert securely under heavy interrupted and continuous cuts. Coolant-through capability is not available on this holder.
