Accupro ACC-BB060400G Boring Bar Solid Carbide Tin

Product Description

The ACCUPRO ACC-BB060400G is a micrograin solid carbide boring bar designed for tight-tolerance internal boring operations on small-diameter features. With a minimum bore diameter of 0.06 inches and a maximum bore depth of 0.4 inches, this bar handles precision work where rigidity and edge retention are critical. The TiN (Titanium Nitride) coating reduces friction and extends tool life across a range of workpiece materials. The 1/8 inch shank diameter and 1.5 inch overall length make it well suited for compact toolholding setups on CNC lathes, manual lathes, and boring head assemblies.

This boring bar is used in precision machining environments where small-bore internal turning is required. Typical applications include finishing bores on small components such as bushings, sleeves, hydraulic valve bodies, and instrumentation parts. The right-hand cutting direction is standard for conventional lathe setups. Machinists working with non-ferrous metals, hardened steels, and engineered plastics will find the micrograin carbide substrate appropriate for maintaining dimensional accuracy at fine chip loads.

Key Features

• Micrograin solid carbide construction provides high rigidity and wear resistance in small-bore applications
• TiN coating reduces built-up edge and extends cutting life
• 0.06 inch minimum bore diameter supports very small internal features
• 0.4 inch maximum bore depth suitable for shallow blind and through bores
• 1/8 inch shank diameter fits standard small-bore toolholders and boring head adapters
• Right-hand cutting direction for standard lathe orientation

Compatibility

Designed for use in toolholders and boring heads accepting a 1/8 inch shank diameter. Suitable for CNC and manual lathes configured for right-hand internal turning operations.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Secure the shank fully within the toolholder to the manufacturer-recommended engagement depth before operation. Ensure the machine spindle is fully stopped and locked out before setting tool height or changing inserts. Verify boring bar runout and alignment before taking finishing passes to maintain bore geometry.
