Accupro B2301150A Boring Bar Submicron Solid Carbide Altin

Product Description

The ACCUPRO B2301150A is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade carbide and finished with an AlTiN coating, it delivers hardness and thermal resistance well-suited for cutting steel, cast iron, and hardened alloys at elevated speeds. The right-hand cutting direction suits standard spindle configurations. The minimum bore diameter is 0.23 inches with a maximum bore depth of 1.15 inches, making it appropriate for small-bore, tight-tolerance work where rigidity and surface finish are critical. Machinists and toolroom professionals use this bar where chatter control and dimensional accuracy are priorities.

This boring bar fits into applications requiring consistent finish quality in small-bore diameters, including precision component machining in aerospace, automotive, and general metalworking shops. The 5/16-inch shank diameter allows seating in standard boring bar holders and quick-change tooling systems sized for that shank. The 2.5-inch overall length suits short-reach setups where bar deflection must be minimized. It is sold individually and is appropriate for production and prototype environments alike.

Key Features

• Submicron solid carbide construction for superior rigidity and edge retention in hard materials
• AlTiN coating improves heat resistance and extends tool life in dry and semi-dry cutting conditions
• Right-hand cutting direction for use with standard CNC and manual lathe spindle rotation
• 0.23-inch minimum bore diameter supports tight-tolerance small-bore applications
• 1.15-inch maximum bore depth keeps the bar in its optimal rigidity range
• 5/16-inch shank diameter fits commonly available boring bar holders

Compatibility

Designed for use in boring bar holders and tooling blocks accepting a 5/16-inch shank diameter. Suitable for CNC turning centers and manual lathes configured for right-hand internal boring.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Ensure the machine spindle is fully stopped and the machine is in an e-stop or lockout-tagout state before mounting or removing the bar. Torque the holder set screws evenly to prevent shank distortion. Minimize bar overhang beyond the holder to reduce deflection and chatter risk during cutting.
