Accupro ACC-BB4904500G Boring Bar 0.49in Solid Carbide Tin

Product Description

The ACCUPRO ACC-BB4904500G is a solid carbide boring bar designed for internal diameter machining in metal cutting applications. Built from micrograin solid carbide with a TiN (titanium nitride) finish coating, this bar delivers consistent cutting performance and extended tool life in demanding turning and boring operations. It features a right-hand cutting direction, a 0.49-inch minimum bore diameter, and a 4.5-inch maximum bore depth. The 0.5-inch shank diameter and 6-inch overall length make it suitable for a range of lathe and machining center setups. Machinists and tool-and-die professionals are the primary users of this tooling.

This boring bar is suited for precision internal boring operations on CNC lathes, manual lathes, and machining centers in job shop, production, and maintenance environments. It handles small-to-medium bore diameter work where tight tolerances and clean surface finishes are required. The micrograin carbide substrate provides strength and wear resistance in ferrous and non-ferrous materials. The TiN coating reduces friction and heat buildup at the cutting edge, extending intervals between tool changes during repetitive production runs.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiN finish coating reduces friction and extends cutting edge life
• Right-hand cutting direction for standard lathe and boring setups
• 0.49-inch minimum bore diameter supports small-bore work
• 4.5-inch maximum bore depth for deeper reach applications
• 0.5-inch shank diameter for common toolholder compatibility

Compatibility

Designed as an OEM-style replacement or direct-use boring bar for standard 0.5-inch shank boring bar holders used on CNC and manual lathes and machining centers.

Installation Notes

Installation is performed by qualified machinists following standard toolroom procedures. Secure the shank firmly in a compatible boring bar holder, ensuring proper overhang is minimized to reduce chatter. Power down and lock out the machine spindle before mounting or removing the tool. Follow the machine manufacturer and tooling supplier guidelines for speeds, feeds, and depth of cut to avoid tool breakage.
