Accupro ACC-BB120250 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB120250 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade carbide with a bright finish, it delivers consistent dimensional accuracy in tight-tolerance bore applications. The bar features a 0.12-inch minimum bore diameter, a 3/16-inch shank diameter, and a 2-inch overall length, making it suited for small-bore finish work where rigidity and tool life matter. Right-hand cut geometry is standard. Machinists and toolroom technicians working with steel, aluminum, and similar machinable materials will find this bar a reliable choice for production and repair work alike.

This boring bar is intended for use in small-bore internal turning applications in both production shop and toolroom environments. Its compact 2-inch overall length and 3/16-inch shank fit standard boring bar holders on small to mid-size lathes. The 0.25-inch maximum bore depth and right-hand cutting direction make it appropriate for through and blind-bore finishing passes where surface finish and size control are priorities.

Key Features

• Submicron solid carbide construction for extended tool life and edge stability
• 0.12-inch minimum bore diameter for small-bore internal turning
• 3/16-inch shank diameter fits standard small-bore toolholders
• Right-hand cut geometry for conventional lathe setup
• Bright finish coating for reduced friction and easier chip evacuation
• 2-inch overall length provides rigidity in short-reach boring applications

Compatibility

Designed as an OEM-style replacement or direct toolroom addition for small-bore internal turning setups requiring a 3/16-inch shank solid carbide boring bar with right-hand cut geometry.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank firmly in the boring bar holder to the toolholder manufacturer's recommended clamping torque before cutting. Ensure the cutting edge is set on center height before taking a pass. Follow all machine guarding and lockout/tagout procedures when changing tooling on any lathe or turning center.
