Accupro ACC-BB3601150 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB3601150 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Manufactured from submicron-grade solid carbide with a bright uncoated finish, it delivers rigidity and wear resistance in close-tolerance bore work. The bar features a right-hand cutting direction, a minimum bore diameter of 0.36 inches, a maximum bore depth of 1.15 inches, and a 3/8-inch shank diameter. Overall length is 2.5 inches. Machinists and tool-and-die professionals use this bar where tight dimensional control and surface finish quality are required in small-bore applications.

This boring bar is suited for residential and industrial machine shops, production turning operations, and toolroom environments. Its submicron solid carbide construction makes it appropriate for boring hardened steels, stainless alloys, cast iron, and non-ferrous materials where high-speed steel tooling lacks the rigidity or edge retention needed to hold tolerance. The compact 2.5-inch overall length and 3/8-inch shank fit standard boring bar holders commonly found on small to mid-size CNC and manual lathes.

Key Features

• Submicron solid carbide construction for superior rigidity and edge retention
• Right-hand cutting direction for standard lathe setups
• Minimum bore diameter of 0.36 inches for small-bore internal turning
• Maximum bore depth of 1.15 inches
• Bright uncoated finish suitable for a wide range of workpiece materials
• 3/8-inch shank diameter fits common boring bar holders

Compatibility

Designed as an OEM-style replacement or direct-fit tooling solution for standard 3/8-inch boring bar holders used in CNC and manual turning center setups requiring a right-hand internal boring tool.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank firmly in the boring bar holder, ensuring adequate overhang is minimized to reduce chatter and deflection. Power down and lock out the machine spindle before changing or adjusting tooling, following applicable shop safety procedures. Verify bore diameter and depth settings against part print requirements before initiating a cutting pass.
