Accupro ACC-BBL060200 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL060200 is a left-hand solid carbide boring bar engineered for precision small-bore machining operations. Manufactured from submicron-grade solid carbide, it delivers the rigidity and edge retention required for tight-tolerance internal diameter work. The bar enters bores as small as 0.0600 inches and reaches a maximum bore depth of 13/64 inches (0.2031 inches), making it well suited for micro-bore applications where tool deflection and surface finish are critical. With a 1/8-inch shank diameter and 1-1/2 inches overall length, it fits standard boring head setups on CNC lathes and machining centers. Machinists and toolroom operators handling small-part production or precision repair work are the primary users of this bar.

This boring bar is intended for internal turning and boring operations on small-diameter features in metalworking applications. Its left-hand cutting direction suits specific tooling orientations and back-boring setups. The compact geometry is appropriate for use on CNC lathes, manual lathes, and machining centers where bore entry diameter constraints limit tooling selection. It is a fit for production shops, toolrooms, and job shops running small precision components in ferrous and non-ferrous materials.

Key Features

• Submicron-grade solid carbide construction for superior hardness and wear resistance in small-bore applications
• Left-hand cutting direction supports specific spindle orientations and back-boring setups
• Minimum bore diameter of 0.0600 inches enables access to very small internal features
• Maximum bore depth of 13/64 inches (0.2031 inches) provides reach within the shank diameter constraints
• 1/8-inch shank diameter fits standard small-bore toolholders and boring heads
• 1-1/2 inches overall length offers a compact, rigid profile to minimize deflection

Compatibility

Designed for use in standard toolholders and boring heads accepting a 1/8-inch shank diameter on CNC and manual lathes or machining centers.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the machine spindle is fully stopped and the machine is in a safe state before mounting or adjusting the boring bar. Secure the shank with appropriate clamping force per the toolholder manufacturer's guidance to prevent tool pullout during cutting. Verify bore entry clearance before initiating a cut to avoid tool or workpiece damage.
