Iscar 6402323 Boring Bar 0.236 in Min Bore Solid Carbide

Product Description

The ISCAR 6402323 is a solid carbide boring bar designed for precision internal turning and bore finishing operations on CNC lathes and machining centers. It features a right-hand cutting direction and a TiN finish coating that extends tool life by reducing friction and wear. The bar carries a 0.006-inch corner radius for controlled surface finish on tight-tolerance bores. With an overall length of 1.1811 inches and a 6 mm shank diameter, this is a compact tool suited to small-bore work where rigidity and dimensional accuracy are critical. ISCAR grade IC228 is the manufacturer-designated carbide substrate for this tool.

This boring bar is intended for machining small-diameter bores with a minimum bore diameter of 0.236 inches and a maximum bore depth of 0.551 inches. It is appropriate for production and job-shop environments where consistent bore geometry is required. Machinists and CNC operators working on precision components in materials suited to TiN-coated carbide tooling will find this bar sized for close-tolerance internal features that larger bars cannot reach.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-bore applications
• TiN finish coating reduces tool wear and friction during cutting
• Right-hand cutting direction for standard lathe spindle rotation
• 0.006-inch corner radius for controlled surface finish
• ISCAR manufacturer grade IC228 carbide substrate
• Compact 1.1811-inch overall length with 6 mm shank diameter for access to tight bore geometries

Compatibility

Designed as an OEM-style replacement or direct-use boring bar for CNC lathes and machining centers accommodating a 6 mm shank diameter and requiring a minimum bore capability of 0.236 inches.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC operator with the machine powered off and in a safe, locked-out state. Secure the shank fully in the boring bar holder to the tool manufacturer recommended engagement length before operation. Verify cutting parameters — speed, feed, and depth of cut — against the IC228 grade recommendations for the workpiece material before starting the cut. Do not exceed the maximum bore depth of 0.551 inches for this tool.
