Accupro ACC-BB4901500A Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB4901500A 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 TiAlN finish coating, it delivers consistent cutting performance and extended tool life in ferrous and non-ferrous materials. The right-hand cutting geometry and 0.5-inch shank diameter provide rigid setup and accurate bore sizing. With a minimum bore diameter of 0.49 inches and a maximum bore depth of 1.5 inches, this bar fits a range of close-tolerance internal finishing applications. Overall length is 3 inches. It weighs 0.3125 pounds.

This boring bar is suited for production and job-shop turning environments where tight bore tolerances are required. It is commonly used by machinists and toolroom operators working on small-diameter through-bores and blind bores in steel, cast iron, aluminum, and similar workpiece materials. The 0.5-inch shank fits standard boring bar holders and quick-change tooling systems used on most turning centers in that size range.

Key Features

• Micrograin solid carbide construction for sharp edges and long tool life
• TiAlN finish coating increases heat and wear resistance at the cutting edge
• Right-hand cut geometry for standard turning center setups
• 0.49-inch minimum bore diameter enables work on small internal features
• 1.5-inch maximum bore depth covers typical short-bore finishing passes
• 0.5-inch shank diameter fits common boring bar holders and quick-change systems

Compatibility

Designed as an OEM-style replacement or direct-use boring bar for standard 0.5-inch boring bar holders and quick-change tool post systems used on CNC and manual turning centers.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the control is in an idle or locked state before mounting or adjusting the boring bar. Secure the shank firmly in the tool holder to the holder manufacturer's recommended clamping procedure to prevent chatter and tool pull-out. Verify bore depth and diameter settings with an appropriate gauge before committing to finish passes.
