Accupro ACC-BB060150A Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB060150A is a solid carbide boring bar designed for precision internal boring on CNC lathes, screw machines, and small-bore turning centers. Built from micrograin solid carbide with a TiAlN finish coating, it delivers the hardness and edge retention needed for tight-tolerance bores in steel, cast iron, and non-ferrous materials. The bar features a right-hand cutting direction, a 0.06-inch minimum bore diameter, and a 0.15-inch maximum bore depth. With a 0.125-inch shank diameter and a 1.5-inch overall length, this bar is sized for small, precise bore applications where rigidity and runout control are critical.

This boring bar is suited for production and job-shop machining environments where small internal diameters must be held to close tolerances. It is commonly used in turning centers, B-axis machines, and Swiss-type lathes when finishing or semi-finishing small bores in components such as valve bodies, hydraulic fittings, and precision housings. The micrograin carbide substrate and TiAlN coating support dry cutting and light flood coolant applications. Setup machinists and CNC operators in metalworking shops are the primary users of this tool.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• TiAlN finish coating reduces heat buildup and extends tool life in ferrous materials
• 0.06-inch minimum bore diameter enables access to very small internal features
• Right-hand cutting direction for standard lathe and turning center setups
• Compact 0.125-inch shank diameter fits standard small-bore tool holders
• 1.5-inch overall length provides a rigid, low-overhang setup for tight-tolerance work

Compatibility

Designed as an OEM-style replacement and standard tooling option for small-bore internal turning applications requiring a 0.125-inch shank boring bar with right-hand cut geometry.

Installation Notes

Installation is performed by qualified setup machinists or CNC operators. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before inserting or changing the bar in the tool holder. Secure the shank firmly in a compatible boring bar holder to the tool holder manufacturer's specified clamping procedure to minimize runout. Verify bore diameter and depth offsets in the machine control before taking the first cut.
