Accupro ACC-BB200700 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB200700 is a solid carbide boring bar designed for internal diameter boring operations on CNC and manual lathes. Built from submicron-grade carbide, this right-hand-cut tool delivers consistent dimensional accuracy in small-bore applications. It features a 1/4-inch shank diameter and an overall length of 2.5 inches, making it well suited for tight-clearance work. The bright finish coating reduces friction and helps maintain surface finish quality in precision bores. Machinists and tool-and-die professionals working on close-tolerance components rely on this bar for repeatable, chatter-resistant cuts in its bore diameter range.

This boring bar is intended for precision machining environments where small internal diameters must be held to tight tolerances. With a minimum bore diameter of 0.2 inches and a maximum bore depth of 0.7 inches, it is appropriate for short, shallow-bore work in ferrous and non-ferrous materials. Typical applications include production turning operations, prototype work, and finishing passes on pre-drilled holes in parts requiring fine surface finish and close dimensional control.

Key Features

• Submicron solid carbide construction for wear resistance and edge stability
• Right-hand cutting direction for standard lathe setups
• Minimum bore diameter of 0.2 inches suits small-diameter internal work
• Maximum bore depth of 0.7 inches keeps the bar rigid in short-reach applications
• Bright finish coating reduces built-up edge and aids chip evacuation
• 1/4-inch shank diameter fits common boring bar holders and turret tooling

Compatibility

Designed as a direct-fit replacement or addition to standard boring bar setups that accept a 1/4-inch shank diameter in CNC turning centers and manual lathes configured for right-hand internal boring operations.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's guidelines for boring bar setup. Ensure the machine spindle is fully stopped and the tool changer or turret is in a safe position before mounting or removing tooling. Secure the shank firmly in the boring bar holder to the specified clamping torque listed in the toolholder documentation, and verify overhang is minimized to reduce deflection. Confirm correct tool offset entry in the machine controller before taking the first pass.
