Kennametal 1094843 Indexable Boring Bar 2.5 in Min Bore

Product Description

The KENNAMETAL 1094843 is an indexable boring bar designed for internal turning and boring operations on CNC lathes and manual turning centers. Built to the A-NE toolholder style in the Top Notch series, it accepts N-style inserts secured by a clamp-type holding method. The shank diameter is 2 inches with a minimum bore diameter of 2.5 inches, making it suited for medium-to-large bore applications. Overall length is 16 inches. The center-to-cutting-edge distance is 1.25 inches. A 1/4-18 NPT coolant-through port is integrated into the body, allowing directed coolant delivery to the cutting zone. The body is steel construction. This bar is right-hand cut. It is sold individually with a minimum order quantity of one.

This boring bar is used in production and job-shop machining environments where precision internal diameter finishing or roughing is required. It is well suited to operations on steel, cast iron, and similar ferrous workpieces in residential toolroom and industrial manufacturing settings. The Top Notch series A-NE style holder is a recognized tooling platform used with compatible N-style insert geometries. Compatible insert selection should be confirmed against the Top Notch series insert catalog for the specific application and material grade. No specific machine model compatibility is stated in the product data.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine in a full stop and locked-out condition per applicable machine tool safety procedures. Confirm shank diameter and minimum bore diameter are compatible with the target machine turret or boring head before mounting. Torque insert clamp screws to the toolholder manufacturer specification found in the product documentation. Connect coolant-through supply to the 1/4-18 NPT port using a properly rated fitting rated for the machine coolant pressure.
