Accupro ACC-BB160750G Boring Bar Micrograin Carbide Tin

Product Description

The ACCUPRO ACC-BB160750G is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from micrograin solid carbide with a titanium nitride (TiN) coating, it delivers consistent cutting performance and extended tool life in ferrous and non-ferrous materials. The bar accepts a minimum bore diameter of 0.16 inches and reaches a maximum bore depth of 0.75 inches. With a 3/16-inch shank diameter and a compact 2-inch overall length, this bar fits standard tool holders used in small-diameter, close-tolerance boring work. Right-hand cut geometry suits conventional lathe setups.

This boring bar is suited for production and job-shop environments where small-bore precision is required. Typical applications include finish boring of hydraulic valve bodies, pump housings, and small mechanical components. The TiN finish reduces friction and helps maintain dimensional accuracy over extended run times. Machinists and toolroom technicians working with CNC turning equipment or toolroom lathes will find this bar appropriate for light to moderate material removal in tight bore profiles.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in small-bore applications
• TiN coating reduces cutting friction and extends tool life
• Minimum bore diameter of 0.16 inches for close-tolerance internal work
• Maximum bore depth of 0.75 inches suits shallow-bore finishing passes
• Right-hand cut geometry compatible with standard lathe setups
• 3/16-inch shank diameter fits common small-bore tool holders

Compatibility

Designed for use in standard tool holders accepting a 3/16-inch shank diameter; suitable for CNC turning centers and manual lathes configured for right-hand cut boring operations.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and in a locked-out state per applicable machine safety procedures. Ensure the shank is properly seated and clamped in the tool holder to the full recommended engagement depth to minimize deflection. Avoid side-loading the bar beyond the rated bore depth, as carbide tooling is brittle and susceptible to fracture under unexpected lateral forces. Inspect the cutting edge for chipping before each use.
