Accupro ACC-BB4903500 Boring Bar Solid Carbide Right Hand

Product Description

The ACCUPRO ACC-BB4903500 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 performance in tight-tolerance bore work. The bar accepts a minimum bore diameter of 0.49 inches and reaches a maximum bore depth of 3.5 inches, making it well suited for moderate-depth finish and semi-finish boring passes. With a 0.5-inch shank diameter and a 6-inch overall length, it fits standard boring bar holders commonly found in production and job-shop environments. Right-hand cut orientation is the standard for conventional lathe setups.

This boring bar is intended for metalworking applications where dimensional accuracy and surface finish inside a bore are critical. Typical use cases include finish boring of bearing housings, hydraulic valve bodies, pump components, and similar machined parts. It is installed and used by machinists and CNC operators in production shops, maintenance machine shops, and tool-and-die environments. The submicron carbide grade provides good wear resistance when running ferrous and non-ferrous materials at moderate cutting speeds.

Key Features

• Submicron solid carbide construction for wear resistance and dimensional stability
• Minimum bore diameter of 0.49 inches suits small to mid-range bore applications
• Maximum bore depth of 3.5 inches allows reach into moderately deep features
• 0.5-inch shank diameter fits standard boring bar holder blocks
• Bright finish coating with no added coating layer that could affect insert seating or shank fit
• Right-hand cut orientation for conventional lathe and CNC turning setups

Compatibility

Designed as a direct-fit replacement or addition for standard 0.5-inch boring bar holders used in CNC turning centers and manual lathes configured for right-hand internal boring operations.

Installation Notes

A qualified machinist should install this boring bar into a compatible 0.5-inch boring bar holder, ensuring the shank is fully seated and clamping screws are tightened evenly. Power down or engage the E-stop on the machine before installing or removing tooling. Confirm runout with a dial indicator before taking finish passes. Do not exceed the tool overhang recommendations of the holder manufacturer, as excessive overhang beyond the 3.5-inch max depth rating can induce chatter and tool deflection.
