Kennametal 1094735 Indexable Boring Bar 0.480 in Right Hand

Product Description

The KENNAMETAL 1094735 is a right-hand indexable boring bar designed for internal turning and bore finishing operations on CNC lathes and manual turning centers. Built to the A-STUN toolholder style, it accepts T221P inserts secured by a screw-clamp holding method for repeatable edge positioning. The steel shank measures 5/8 inch (15.88 mm) in diameter with a 6-inch (152.40 mm) overall length, and the minimum bore diameter is 0.480 inch (12.19 mm). Through-coolant capability is supported via a 1/8-27 NPT coolant port, directing fluid to the cutting zone to improve chip evacuation and extend insert life in deep-bore applications.

This boring bar is suited for precision bore work in metalworking shops, production machining environments, and toolroom applications. The 0.480-inch minimum bore diameter makes it appropriate for small-diameter internal features where rigidity and reach must be balanced. The 6-inch overall length provides adequate reach for moderate-depth bores while maintaining shank stiffness. Machinists working with steel, cast iron, and similar materials in turning operations will find this tool a direct-fit solution for tight-tolerance bore sizing and finishing passes.

Key Features

• A-STUN toolholder style accepts T221P indexable inserts
• 0.480 inch (12.19 mm) minimum bore diameter for small internal features
• Through-coolant design with 1/8-27 NPT port for improved chip control
• Screw-clamp insert holding method for secure, repeatable positioning
• Steel shank construction for rigidity during internal turning operations
• Right-hand cutting orientation; 6-inch overall length

Compatibility

Designed to accept T221P inserts in the A-STUN insert style. Intended for use in standard 5/8-inch boring bar holders on CNC lathes and manual turning centers configured for right-hand internal turning operations.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank in a compatible 5/8-inch boring bar holder and verify tool overhang does not exceed recommended limits for the holder style to minimize chatter. Connect through-coolant supply to the 1/8-27 NPT port using appropriate fittings before beginning cuts. Confirm machine spindle is at a full stop and all axes are locked before changing or indexing inserts.
