Accupro ACC-BBL2301150 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BBL2301150 is a solid carbide boring bar designed for internal bore machining operations requiring tight tolerances and fine surface finishes. Built from submicron-grade carbide with a bright finish coating, it delivers consistent rigidity and wear resistance in demanding cutting applications. The bar handles a minimum bore diameter of 0.23 inches and a maximum bore depth of 1.15 inches, with a 5/16-inch shank diameter and an overall length of 2.5 inches. It is configured for left-hand cutting direction, making it suited for specific lathe setups and reverse-rotation applications. Machinists and toolroom technicians install this bar in CNC lathes, manual lathes, and boring heads where precise internal diameter control is required.

This boring bar is applicable in precision machining environments including job shops, production facilities, and toolrooms working with ferrous and non-ferrous materials. The submicron carbide substrate performs well in interrupted cuts and abrasive materials where high-speed steel tooling falls short. Its compact bore depth and small minimum bore diameter make it a practical choice for small-diameter internal features in turned components. Left-hand cut orientation suits specific workholding configurations or climb-boring operations on compatible machines.

Key Features

• Submicron solid carbide construction for superior hardness and wear resistance
• Left-hand cutting direction for reverse-rotation and specialized lathe setups
• Minimum bore diameter of 0.23 inches for small internal features
• Maximum bore depth of 1.15 inches suitable for shallow-to-mid depth bores
• Bright finish coating reduces friction and aids chip evacuation
• 5/16-inch shank diameter for secure tool holder clamping

Compatibility

Designed as an OEM-style replacement or direct tooling selection for lathes and boring setups accepting a 5/16-inch shank boring bar with left-hand cut geometry.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the machine is powered down or in an e-stop state before mounting or removing the boring bar. Secure the shank firmly in a compatible tool holder or boring head to the holder manufacturer's specified clamping procedure to prevent chatter or tool pull-out. Verify cutting direction matches spindle rotation before initiating a cut.
