Accupro ACC-BB4901250G Boring Bar 0.49 in Solid Carbide Tin

Product Description

The ACCUPRO ACC-BB4901250G is a right-hand-cut solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Manufactured from micrograin solid carbide and finished with a TiN coating, this bar delivers consistent performance when machining tight-tolerance bores in steel, cast iron, and non-ferrous materials. It accepts a minimum bore diameter of 0.49 inches and reaches a maximum bore depth of 1.25 inches. The 0.5-inch shank diameter and 3-inch overall length make it well-suited for close-tolerance work in a standard tool block or boring head setup. Machinists and tool-and-die professionals rely on this geometry for clean finish passes and repeatable diameter control.

This boring bar is intended for use in metal-cutting environments where dimensional accuracy is critical. It fits standard 0.5-inch shank holders commonly found in manual and CNC turning applications. The right-hand cutting direction suits conventional lathe setups. The micrograin carbide substrate and TiN finish coating extend tool life compared to uncoated high-speed steel alternatives, making this bar a practical choice for production shops and job shops running medium to high volumes of turned components.

Key Features

• Micrograin solid carbide substrate for superior hardness and edge retention
• TiN finish coating reduces friction and extends tool life in ferrous and non-ferrous materials
• Minimum bore diameter of 0.49 inches suits tight internal features
• Maximum bore depth of 1.25 inches for moderate-reach internal operations
• Right-hand cutting direction for standard lathe and boring head orientation
• 0.5-inch shank diameter fits common toolholders without adapters

Compatibility

Designed as an OEM-style replacement or direct-use boring bar for standard 0.5-inch shank boring head holders and toolposts used in CNC and manual turning applications.

Installation Notes

Installation is performed by qualified machinists or tool-setup personnel. Ensure the lathe or machining center is fully powered down and the spindle is locked before seating or removing the bar from the toolholder. Secure the shank firmly in the holder to the manufacturer-specified clamping procedure to prevent chatter and maintain bore accuracy. Inspect the cutting edge for wear or chipping before each use and replace the bar if edge integrity is compromised.
