Kennametal 1096423 A-mcln Indexable Boring Bar 2.4in Rh

Product Description

The KENNAMETAL 1096423 is a right-hand A-MCLN style indexable boring bar engineered for precision internal turning operations on CNC and manual lathes. Built on the Kenloc series platform, it features a 2-inch steel shank, a 16-inch overall length, and a 2.4-inch minimum bore diameter, making it suited for large-bore finishing and semi-finishing work. The tool uses CN.. style inserts held by a combination screw and clamp method, delivering secure insert retention under heavy cutting loads. Through-coolant capability via a 1/4-18 NPT coolant port keeps the cutting zone clear and helps extend insert life in demanding applications.

This boring bar is designed for machining operations that require tight bore tolerances and consistent surface finish in medium-to-large diameter bores. The negative rake geometry at a 5-degree rake angle and a -5-degree lead angle suits it for aggressive stock removal in steel and other ferrous materials. Typical applications include job shop and production environments where large-diameter internal features must be held to close tolerances. The 16-inch overall length accommodates deep bore access that shorter toolholders cannot reach.

Key Features

• A-MCLN Kenloc toolholder style with screw and clamp insert retention for rigid, repeatable insert seating
• 2.4-inch minimum bore diameter supports large internal turning without interference
• 16-inch overall length provides extended reach for deep-bore applications
• Through-coolant design with 1/4-18 NPT port directs coolant directly to the cutting edge
• Negative rake geometry with 5-degree rake angle and -5-degree lead angle for stable cutting action
• Steel tool body construction for durability and vibration resistance in production environments

Compatibility

Accepts CN.. style indexable inserts with a 5/8-inch inscribed circle and 1/4-inch insert thickness. Designed for use on CNC turning centers and manual lathes equipped to accommodate a 2-inch round shank toolholder.

Installation Notes

Installation and setup should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the toolholder. The 2-inch shank must be secured in a compatible boring bar holder or turret pocket to the appropriate clamping torque specified by the machine manufacturer. Verify coolant line connection to the 1/4-18 NPT port is leak-free before running the spindle.
