Accupro ACC-BB080400G Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB080400G is a solid carbide boring bar designed for precision internal turning and boring operations on CNC lathes and manual turning centers. Built from micrograin solid carbide, it delivers the rigidity and edge retention required for tight-tolerance bores in hardened and abrasive workpiece materials. A titanium nitride (TiN) finish coating reduces friction and extends tool life. With a minimum bore diameter of 0.08 inches and a maximum bore depth of 0.4 inches, this bar handles small-diameter work where standard tooling cannot reach. The right-hand cutting direction suits standard spindle rotation setups on most turning centers.

This boring bar is suited for small-bore finish and semi-finish operations in precision machining environments, including job shops, tool rooms, and production turning cells. It is particularly well-matched to applications in medical, aerospace, and instrumentation components where bore diameters below 0.1 inches are common. The 1/8-inch shank diameter fits standard small-bore toolholders and quick-change turrets configured for that size. Overall length is 1.5 inches, keeping the bar compact for minimal overhang and maximum stability during the cut.

Key Features

• Micrograin solid carbide construction for superior edge sharpness and wear resistance
• TiN finish coating reduces cutting friction and improves tool longevity
• 0.08-inch minimum bore diameter enables work in very small internal diameters
• Right-hand cutting direction compatible with standard spindle rotation
• 1/8-inch shank diameter fits common small-bore toolholders and turret stations
• Compact 1.5-inch overall length minimizes overhang and chatter risk

Compatibility

Designed for use in CNC and manual lathes equipped with toolholders or turret stations accepting a 1/8-inch shank boring bar with right-hand cutting geometry.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine before mounting or removing the bar. Secure the shank fully within the toolholder to the recommended grip length to reduce deflection; avoid excessive overhang beyond what the bore depth requires. Inspect the cutting edge for chipping or wear before each use, as solid carbide tools are brittle and sensitive to interrupted cuts or improper seating.
