Accupro ACC-BB100400 Boring Bar Solid Carbide Right Hand

Product Description

The ACCUPRO ACC-BB100400 is a submicron solid carbide boring bar designed for precision internal boring operations on small-diameter holes. With a minimum bore diameter of 0.1 inches and a maximum bore depth of 0.4 inches, this bar handles tight-tolerance finish boring in difficult-to-reach bores. The 1/8-inch shank diameter keeps the tool compact, and the 1-1/2-inch overall length suits short-reach setups on CNC lathes, machining centers, and manual boring equipment. The bright finish coating reduces friction and aids chip evacuation. Machinists and toolroom technicians working on small-bore applications rely on submicron carbide grade for its fine grain structure and resistance to edge wear.

This boring bar is suited for precision small-bore internal turning in production and toolroom environments. Typical applications include finish boring of bushings, bearing bores, valve bodies, and hydraulic components where tight diameter tolerances and fine surface finishes are required. The right-hand cutting direction is standard for conventional lathe and boring-mill setups. The compact shank and short overall length make it practical for multi-axis CNC work holding and tight-clearance fixturing.

Key Features

• Submicron solid carbide construction for superior wear resistance and edge retention in small-bore applications
• Minimum bore diameter of 0.1 inches suits very small internal features
• Maximum bore depth of 0.4 inches for short-reach precision boring
• 1/8-inch shank diameter for use in standard small-bore tool holders and collet chucks
• Right-hand cut direction for conventional lathe and CNC turning center setups
• Bright finish coating reduces cutting friction and aids chip flow

Compatibility

Designed as a standard right-hand solid carbide boring bar compatible with tool holders and boring head systems that accept a 1/8-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the machine is powered down before mounting or removing the boring bar. Secure the shank firmly in the tool holder to the full recommended engagement depth to minimize overhang deflection and chatter. Inspect the cutting edge for chips or wear before each use, as carbide tools are brittle and should not be subjected to interrupted cuts or excessive side loads beyond their rated capacity.
