Micro 100 BB-180500 Boring Bar Solid Carbide Right Hand

Product Description

The MICRO 100 BB-180500 is a solid carbide boring bar designed for internal diameter turning and boring operations on lathes and machining centers. With a minimum bore diameter of 0.18 inches and a maximum bore depth of 0.5 inches, this bar handles small-bore finish and semi-finish work where precision is critical. The 0.25-inch shank diameter and 2.5-inch overall length suit compact tool holders and tight setups. A 0.006-inch corner radius provides a controlled blend between cutting surfaces, reducing chatter and improving surface finish on close-tolerance bores. Licensed machinists and CNC operators are the primary users of this tooling.

This boring bar is suited for small-bore internal turning in job shops, production machining, and toolroom environments. The right-hand cutting direction is standard for conventional lathe setups where the spindle rotates counterclockwise when viewed from the tailstock. Solid carbide construction makes it a strong choice for hardened materials, cast iron, aluminum, and non-ferrous alloys where high rigidity and wear resistance are required. It is appropriate for both manual and CNC lathe applications requiring a minimum bore of 0.18 inches.

Key Features

• Minimum bore diameter of 0.18 inches for small-bore internal turning
• Maximum bore depth of 0.5 inches suits shallow blind and through-bore work
• Solid carbide construction provides rigidity and wear resistance
• 0.006-inch corner radius for controlled surface finish
• Right-hand cut for standard lathe spindle rotation
• 0.25-inch shank diameter fits common boring bar holders

Compatibility

Designed as an OEM-style replacement and standard tooling option for lathes and machining centers accepting a 0.25-inch shank boring bar with right-hand cut orientation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the machine is powered down before inserting or adjusting the boring bar in the tool holder. Confirm shank diameter compatibility with the tool holder bore before clamping. Do not exceed the maximum bore depth rating of 0.5 inches to avoid tool deflection or breakage.
