Accupro ACC-BB360900 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB360900 is a solid carbide boring bar designed for precision internal bore operations on CNC lathes and manual turning centers. Built from submicron-grade solid carbide, it delivers the rigidity and wear resistance required for tight-tolerance work in ferrous and non-ferrous materials. The bar features a right-hand cutting direction, a minimum bore diameter of 0.36 inches, and a maximum bore depth of 0.9 inches. With a 3/8-inch shank diameter and an overall length of 2.5 inches, it fits standard boring bar holders used in production and job-shop turning applications. The bright finish indicates an uncoated surface, keeping cutting geometry sharp at the edge.

This boring bar is suited for small-diameter internal turning where rigidity is critical to achieving fine surface finishes and dimensional accuracy. It is appropriate for residential machine shops, production floors, and toolrooms running tight-bore work in aluminum, steel, stainless, and similar materials. The compact overall length and shank size make it a practical choice for Swiss-style, gang-tooled, or conventional lathe setups where clearance is limited and bore diameter falls in the sub-half-inch range.

Key Features

• Submicron solid carbide construction provides high rigidity and resistance to chipping in demanding bore operations
• Minimum bore diameter of 0.36 inches suits small-diameter internal turning applications
• Maximum bore depth of 0.9 inches allows adequate reach for typical short-bore work
• Right-hand cutting direction compatible with standard lathe spindle rotation
• 3/8-inch shank diameter fits common boring bar holders and quick-change tooling systems
• Bright finish uncoated surface preserves sharp edge geometry for non-ferrous and finish-cut applications

Compatibility

Designed as an OEM-style replacement or direct-use boring bar for lathes and turning centers equipped with standard 3/8-inch boring bar holders accepting solid carbide tooling.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully in the boring bar holder with appropriate set screws, ensuring minimum overhang to reduce deflection. Power down and lock out the machine spindle before changing or adjusting tooling per standard lockout/tagout procedures. Do not exceed the recommended bore depth or use the bar in interrupted cuts beyond its rated application without verifying manufacturer guidance.
