Accupro ACC-BB360750 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB360750 is a solid carbide boring bar designed for internal boring operations on CNC lathes, manual lathes, and boring machines. Built from submicron-grade carbide with a bright finish, it delivers tight tolerances and consistent surface finishes in ferrous and non-ferrous materials. The bar features a right-hand cutting direction, a 0.36-inch minimum bore diameter, a 0.75-inch maximum bore depth, and a 3/8-inch shank diameter with a 2.5-inch overall length. Machinists and toolroom technicians use this bar where rigidity and dimensional accuracy are critical in small-bore applications.

This boring bar suits production and job-shop environments requiring precise bore sizing in small-diameter workpieces. Its submicron carbide construction supports higher cutting speeds and longer tool life compared to standard carbide grades, making it a practical choice for high-cycle runs or precision one-off work. The right-hand cut orientation fits standard tool holders in the most common lathe and boring machine setups. Typical applications include bearing bores, bushing seats, and close-tolerance through or blind bores in both manual and CNC turning operations.

Key Features

• Submicron solid carbide construction for extended tool life and consistent edge integrity
• 0.36-inch minimum bore diameter suits small-bore precision work
• 0.75-inch maximum bore depth for through and blind bore applications
• Right-hand cutting direction for standard lathe and boring machine setup
• Bright finish coating reduces built-up edge on non-ferrous materials
• 3/8-inch shank diameter fits common boring bar holders

Compatibility

Designed as a direct-fit replacement or supplemental boring bar for standard 3/8-inch boring bar holders used in CNC and manual turning centers, lathes, and boring machines configured for right-hand internal boring operations.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing the boring bar from the holder. Ensure the shank is fully seated and clamped per the tool holder manufacturer's torque recommendations. Verify boring bar overhang is minimized to reduce chatter and maintain dimensional accuracy during the cut.
