Accupro ACC-BB3601250 Boring Bar Solid Carbide Right Hand

Product Description

The ACCUPRO ACC-BB3601250 is a 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, it delivers tight tolerances and consistent surface finishes in ferrous and non-ferrous materials. The right-hand cutting direction suits the majority of standard lathe setups. With a 3/8 inch shank diameter and 2.5 inch overall length, this bar fits common toolpost and boring head setups without adapters in most light-to-medium duty applications. It weighs 0.1875 pounds and ships as a single unit.

This boring bar is suited for shop machinists, tool and die makers, and production turning operations where minimum bore diameter is a critical constraint. The 0.36 inch minimum bore diameter makes it practical for small-diameter internal features in workpieces where standard insert tooling cannot reach. Maximum bore depth reaches 1.25 inches, making it a solid choice for through-holes and blind bores in short-chucked workpieces on both manual and CNC turning equipment.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance in demanding cuts
• 0.36 inch minimum bore diameter for access to tight internal features
• 1.25 inch maximum bore depth suits short blind and through-bore applications
• Right-hand cutting direction compatible with standard lathe rotation
• Bright finish coating — no additional surface treatment required out of the box
• 3/8 inch shank diameter fits common boring head and toolpost holders

Compatibility

Designed as a standard right-hand boring bar for use in 3/8 inch boring bar holders on CNC and manual turning centers where a 0.36 inch minimum bore diameter and 1.25 inch maximum bore depth are within the required parameters.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before seating or removing the boring bar from the holder. Ensure the shank is fully engaged in the holder to the recommended minimum grip length to reduce chatter and tool deflection. Follow the machine tool manufacturer and toolholder manufacturer guidelines for clamping torque and overhang limits.
