Accupro ACC-BB140250 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB140250 is a solid carbide boring bar engineered for internal diameter boring operations on lathes and machining centers. Manufactured from submicron-grade carbide with a bright finish coating, this bar offers the rigidity and wear resistance needed for tight-tolerance work in small-bore applications. It accepts a minimum bore diameter of 0.14 inches and reaches a maximum bore depth of 0.25 inches. The shank diameter measures 3/16 inches with an overall length of 2 inches. Machinists working in production or toolroom environments will find this bar suited to precision finishing and semi-finishing passes where consistency and tool life matter.

This boring bar is suited to small-bore internal turning operations in both manual and CNC lathe setups. Its compact geometry targets bore diameters starting at 0.14 inches, making it appropriate for intricate workpieces, instrument components, and close-tolerance fittings. Right-hand cutting direction is standard for conventional spindle rotation. The submicron carbide grade supports use in a range of ferrous and non-ferrous materials where edge sharpness and thermal stability are priorities for machinists and tool and die professionals.

Key Features

• Submicron solid carbide construction for high wear resistance and edge retention
• Minimum bore diameter of 0.14 inches for tight small-bore applications
• Maximum bore depth of 0.25 inches
• 3/16 inch shank diameter with 2 inch overall length for compact tooling setups
• Bright finish coating reduces friction and aids chip flow
• Right-hand cutting direction for standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct tooling solution for boring bar holders accepting a 3/16 inch shank diameter in manual and CNC lathe applications.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before changing or adjusting tooling. Secure the shank firmly in the boring bar holder to the appropriate clamping specification for your tool block. Verify bore alignment and tool overhang before taking a test cut, and always use appropriate cutting fluid or coolant for the workpiece material.
