Accupro B060400A Boring Bar 0.06 in Min Bore Solid Carbide

Product Description

The ACCUPRO B060400A is a solid carbide boring bar designed for precision internal boring operations on CNC machining centers, lathes, and small-bore turning setups. Built from submicron-grade solid carbide and finished with an AlTiN coating, this bar handles tight-tolerance bores in hardened materials, stainless steels, and heat-resistant alloys. It delivers a minimum bore diameter of 0.06 inches and a maximum bore depth of 0.4 inches. The right-hand cutting direction suits standard spindle configurations. With a 0.125-inch shank diameter and an overall length of 1.5 inches, this is a compact tool for fine internal work where rigidity and dimensional accuracy are critical. Machinists and tooling specialists rely on this class of bar for finishing passes in small-diameter bores.

This boring bar is suited to light-duty precision boring in production and job-shop environments. It is commonly used in CNC turning centers and machining cells where small bores require consistent surface finish and close dimensional tolerance. Typical applications include instrument components, hydraulic valve bodies, small mechanical assemblies, and precision fixtures. The AlTiN coating extends tool life in dry and semi-dry cutting conditions, making it a practical choice for high-speed finishing passes. The compact shank and short overall length reduce overhang and help maintain bore accuracy in difficult-to-reach internal features.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance in precision boring
• AlTiN finish coating extends tool life in high-speed and dry-cutting applications
• Minimum bore diameter of 0.06 inches for very small internal features
• Maximum bore depth of 0.4 inches
• Right-hand cutting direction for standard spindle setups
• Compact 0.125-inch shank diameter and 1.5-inch overall length minimize overhang

Compatibility

Designed as an OEM-style boring bar for use in standard boring bar holders accepting a 0.125-inch round shank, compatible with CNC lathes and machining centers configured for right-hand internal turning operations.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before inserting or adjusting the boring bar in its holder. Verify shank runout and holder clamping torque per the machine tool manufacturer specifications before taking a cut. Inspect the cutting edge for chipping or wear before each use, as submicron carbide tools are brittle and sensitive to interrupted cuts or excessive radial load.
