Accupro B2001100R Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO B2001100R is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and machining centers. Built from submicron-grade carbide, it delivers the rigidity and wear resistance required for tight-tolerance bores in hardened steels, cast iron, and other difficult materials. The bar has a minimum bore diameter of 0.2000 inches and a maximum bore depth of 1.1000 inches, making it well suited for small, deep bores where deflection control is critical. Overall length is 2.5 inches. Machinists and tool-and-die professionals rely on this geometry for consistent surface finish and dimensional accuracy in production and repair applications.

This boring bar is used in job shops, production machining facilities, and maintenance environments where small-diameter internal features require precise sizing. The right-hand cutting direction suits standard spindle rotation on most CNC and manual lathes. The 1/4-inch shank diameter fits common boring bar holders, quick-change toolposts, and live tooling turrets. It is appropriate for both finishing passes and light roughing passes in small bores across a range of workpiece materials.

Key Features

• Submicron solid carbide construction for superior rigidity and wear resistance
• Minimum bore diameter of 0.2000 inches for small-hole internal turning
• Maximum bore depth of 1.1000 inches suits deep, narrow bore profiles
• Right-hand cutting direction compatible with standard spindle rotation
• 1/4-inch shank diameter fits common boring bar holders and quick-change systems
• Compact 2.5-inch overall length reduces overhang and vibration

Compatibility

Designed as an OEM-style replacement or direct tooling selection for boring bar holders accepting a 1/4-inch round shank with right-hand cutting geometry.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Ensure the machine spindle is fully stopped and locked out before mounting or adjusting the boring bar. Secure the shank firmly in the holder to minimize overhang and prevent chatter. Verify bore diameter and depth settings with appropriate gauging before committing to a finish pass.
