Accupro ACC-BBL2301000 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL2301000 is a left-hand cut solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade solid carbide with a bright finish, this bar delivers the rigidity and edge retention required for tight-tolerance bore work. It accepts a minimum bore diameter of 0.23 inches and reaches a maximum bore depth of 1 inch. The 5/16-inch shank diameter and 2.5-inch overall length make it a compact, high-performance tooling solution suited to small-diameter bore applications in production and job-shop environments.

This boring bar is intended for machinists and tooling specialists working on small-bore internal turning operations. The left-hand cutting direction suits specific fixturing setups and back-boring applications where right-hand tooling cannot be used. Its submicron carbide construction makes it well suited for finishing passes on ferrous and non-ferrous materials where surface finish and dimensional accuracy are critical. Typical users include CNC lathe operators and manual machinists in aerospace, automotive, and general precision machining environments.

Key Features

• Submicron solid carbide construction for superior hardness and wear resistance
• Left-hand cutting direction for back-boring and specialized fixturing setups
• Bright finish coating for reduced friction and improved chip flow
• Minimum bore diameter of 0.23 inches for small-bore applications
• Maximum bore depth of 1 inch with a compact 2.5-inch overall length
• 5/16-inch shank diameter for standard boring bar holders

Compatibility

Designed as an OEM-style replacement and standard-fitment boring bar for 5/16-inch shank boring bar holders used in small-diameter internal turning applications on CNC and manual lathes.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and all axes are locked before changing or setting tooling. The boring bar must be clamped securely in a compatible 5/16-inch boring bar holder and set to the correct centerline height before cutting. Follow the machine tool manufacturer and shop safety guidelines when setting tool offsets and running test cuts.
