Accupro ACC-BB200600G Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB200600G is a solid carbide boring bar designed for precision internal boring operations on CNC and manual lathes. Built from micrograin carbide stock, it delivers consistent edge strength and wear resistance across tight-tolerance bores. The bar features a right-hand cutting direction and a TiN (Titanium Nitride) coating that reduces friction and extends tool life. With a 0.2-inch minimum bore diameter and a 0.6-inch maximum bore depth, it is suited for small-diameter work where rigidity and runout control are critical. The 0.25-inch shank diameter and 2.5-inch overall length make it compatible with standard small-bore toolholding systems used in precision machining environments.

This boring bar is used in production and job-shop machining for boring small internal diameters in ferrous and non-ferrous materials. It is well suited for applications requiring close tolerances and fine surface finishes in bores starting at 0.2 inches. Machinists working on watch components, hydraulic valve bodies, small pump housings, and similar precision parts will find this bar appropriate for their tooling lineup. It installs into a standard 0.25-inch round-shank boring bar holder or boring head with a matching bore.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• TiN coating reduces cutting friction and improves tool longevity
• Right-hand cutting direction for standard lathe and boring head setups
• 0.2-inch minimum bore diameter enables entry into tight, small-diameter workpieces
• 0.25-inch shank diameter fits common small-bore toolholding systems
• 2.5-inch overall length provides reach while maintaining rigidity

Compatibility

Designed for use with standard 0.25-inch round-shank boring bar holders and boring heads used in CNC and manual turning applications requiring a right-hand solid carbide boring bar.

Installation Notes

Installation is performed by a machinist or tooling technician. Power down and lock out the machine spindle before changing tooling. Secure the shank fully within the holder to the manufacturer-recommended engagement depth to minimize deflection and chatter. Verify tool overhang is minimized relative to bore depth for best performance and surface finish.
