Accupro B2001200A Boring Bar 0.2in Min Bore Solid Carbide

Product Description

The ACCUPRO B2001200A is a solid carbide boring bar designed for internal diameter boring operations on CNC lathes and turning centers. Built from submicron-grade carbide with an AlTiN finish coating, this bar delivers wear resistance and thermal stability in demanding cutting conditions. It has a minimum bore diameter of 0.2 inches and a maximum bore depth of 1.2 inches (1-13/64 inches). The shank diameter is 0.25 inches and the overall length is 2.5 inches. The right-hand cutting direction suits standard lathe setups. This tool is installed by machinists and tool-and-die professionals working in precision machining environments.

This boring bar is suited for finishing and semi-finishing small-diameter bores in ferrous and non-ferrous materials. The submicron carbide grade supports higher cutting speeds and feeds compared to standard carbide grades, making it appropriate for production turning applications where dimensional accuracy and surface finish are critical. The compact geometry fits tight bore entries, and the AlTiN coating extends tool life in dry or minimal-lubrication cutting strategies.

Key Features

• Submicron solid carbide construction for enhanced hardness and edge retention
• AlTiN finish coating provides oxidation resistance and reduces thermal wear at the cutting edge
• Minimum bore diameter of 0.2 inches for small-diameter internal operations
• Maximum bore depth of 1.2 inches supports moderate-depth passes in a single bar
• Right-hand cutting direction for standard lathe and turning center configurations
• 0.25-inch shank diameter for compatibility with common boring bar holders

Compatibility

Designed as a direct-fit boring bar for CNC lathes and turning centers that accept a 0.25-inch shank boring bar holder with right-hand tooling orientation.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling setup procedures. Secure the shank fully in the boring bar holder to the recommended clamping depth to minimize overhang and chatter. Power down the spindle and confirm the machine is in a safe state before changing or indexing any tooling. Follow shop safety protocols and applicable machine guarding requirements when setting up cutting tools.
