Accupro ACC-BB1601000 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB1601000 is a solid carbide boring bar designed for precise internal boring operations on metal workpieces. Built from submicron-grade carbide with a bright finish coating, it delivers consistent tool life and dimensional accuracy in tight-tolerance applications. The bar features a right-hand cutting direction, a minimum bore diameter of 0.16 inches, and a maximum bore depth of 1 inch. With a 3/16-inch shank diameter and an overall length of 2 inches, it fits compact toolholding setups on CNC lathes and manual boring machines. Machinists and toolroom operators use this bar for finish boring holes where rigidity and precision are critical.

This boring bar is suited for small-diameter internal boring on production and toolroom lathes, CNC turning centers, and bench-top boring machines. It is appropriate for residential shop environments and light industrial manufacturing settings where tight hole tolerances are required. The submicron solid carbide construction makes it effective on a range of materials including steel, cast iron, and non-ferrous alloys. Single-piece packaging makes it a direct add-to-toolbox replacement when worn bars need swapping out during a job.

Key Features

• Submicron solid carbide construction for extended tool life in tight-tolerance boring
• Right-hand cutting direction for standard lathe and boring machine setups
• Minimum bore diameter of 0.16 inches for small-hole internal boring applications
• Maximum bore depth of 1 inch with a 3/16-inch shank diameter for rigid overhang control
• Bright finish coating — no additional surface treatment needed out of the box
• Compact 2-inch overall length fits short-reach toolholders and small-machine setups

Compatibility

Designed as an OEM-style replacement boring bar for use in standard 3/16-inch shank toolholders on CNC turning centers and manual lathes requiring right-hand internal boring capability.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down the machine and engage the spindle lock before seating or removing the boring bar from the toolholder. Secure the shank in a matched-bore toolholder to the manufacturer-recommended clamping method — avoid over-extension beyond the stated maximum bore depth to prevent deflection and chatter. Verify cutting direction matches spindle rotation before engaging the workpiece.
