Accupro ACC-BB200900 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB200900 is a solid carbide boring bar designed for internal diameter boring operations on CNC lathes and manual turning centers. Built from submicron-grade carbide, this right-hand cutting tool delivers the rigidity and edge retention needed for tight-tolerance bores in ferrous and non-ferrous materials. It accepts a minimum bore diameter of 0.2 inches and reaches a maximum bore depth of 0.9 inches. With a 1/4-inch shank diameter and an overall length of 2.5 inches, the ACC-BB200900 fits compact toolholders and swiss-style setups where space is limited. The bright, uncoated finish suits a wide range of cutting fluids and dry-cutting applications.

This boring bar is suited for production and job-shop environments where small-diameter internal features require precise, repeatable results. Typical applications include finish boring of hydraulic fittings, precision bushings, valve bodies, and similar close-tolerance components. The right-hand cutting direction makes it compatible with conventional forward-spindle turning programs. Machinists and toolroom operators install this bar in standard 1/4-inch boring bar holders or block-style tooling systems.

Key Features

• Submicron solid carbide construction for high rigidity and long tool life
• Minimum bore diameter of 0.2 inches for small internal features
• Maximum bore depth of 0.9 inches
• Right-hand cutting direction for standard forward-spindle turning
• 1/4-inch shank diameter fits common boring bar holders
• Bright/uncoated finish compatible with a broad range of cutting conditions

Compatibility

Designed as an OEM-style boring bar for use in any CNC lathe or manual turning center equipped with a standard 1/4-inch boring bar holder or block tooling system.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or removing the bar from its holder. Ensure the shank is clamped at the recommended minimum engagement depth per the toolholder manufacturer's guidelines to prevent chatter. Do not exceed the maximum bore depth of 0.9 inches, as overreach reduces rigidity and increases the risk of tool deflection or breakage.
