Kennametal 1096469 A-mvun Indexable Boring Bar Left Hand

Product Description

The KENNAMETAL 1096469 is a left-hand A-MVUN indexable boring bar designed for precision internal turning and boring operations on CNC lathes and machining centers. Built on the Kenloc toolholding system, it features a 1-1/2 inch (38.10 mm) shank diameter and a 14 inch (355.60 mm) overall length, with a minimum bore diameter of 2.0000 inches (50.80 mm). The steel body supports through-coolant delivery via a 1/4-18 NPT coolant port, making it suitable for deep-bore applications where chip evacuation and heat control are critical. Machinists and toolroom professionals working in production or job-shop environments install this bar on lathes configured for left-hand cutting.

This boring bar is suited for internal diameter finishing and semi-finishing in moderate-to-large bore applications on CNC turning centers. The through-coolant capability supports extended reach and high-speed cutting conditions. Its negative rake geometry and -3 degree lead angle are appropriate for general-purpose boring in steel, cast iron, and similar materials. It is installed by machinists and CNC setup technicians in shop environments where close-tolerance internal features are required.

Key Features

• Left-hand cutting orientation for CNC lathes configured for reverse-rotation or left-hand boring operations
• Through-coolant delivery via 1/4-18 NPT port for improved chip evacuation and tool life in deep bores
• Kenloc insert clamping system using screw and clamp method for rigid, repeatable insert indexing
• Accepts VN.. style inserts with a 3/8 inch inscribed circle and 3/16 inch thickness
• Negative rake at 5 degrees with -3 degree lead angle for stable cutting on hardened and tough materials
• Steel body construction for vibration damping and durability in production environments

Compatibility

Designed for use with VN.. series inserts with a 3/8 inch inscribed circle. Compatible with the A-MVUN toolholder style within the Kenloc system. No additional specific model or machine compatibility data was provided in the product input.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom technicians. Power down and lock out the machine spindle before mounting or removing the boring bar from the turret or tool block. Secure the shank per machine tool manufacturer torque specifications and verify insert seating and clamp engagement before running. Connect the coolant line to the 1/4-18 NPT port only after confirming thread compatibility with the machine coolant system.
