Accupro ACC-BB1801500G Boring Bar Micrograin Carbide Tin

Product Description

The ACCUPRO ACC-BB1801500G is a solid micrograin carbide boring bar designed for internal diameter machining in tight-tolerance applications. It features a minimum bore diameter of 0.18 inches and a maximum bore depth of 1.5 inches, making it well suited for small-bore work where rigidity and cutting-edge integrity are critical. The 0.25-inch shank diameter and 2.5-inch overall length keep the tool compact and easy to set in standard toolholders. A TiN finish coating adds surface hardness and wear resistance at the cutting edge. Right-hand cut geometry is standard. This bar is installed and operated by machinists and CNC lathe operators in job shop and production environments.

This boring bar is used in lathe and turning center operations requiring precise internal bore finishing. Its micrograin carbide construction handles a range of workpiece materials including steel, aluminum, and cast iron. The short overall length and small shank diameter make it a practical choice for live-tooling setups, manual lathes, and compact CNC turning centers where clearance is limited. No specific OEM system compatibility is listed for this tool beyond standard 0.25-inch shank toolholder fitment.

Key Features

• Micrograin solid carbide construction for improved toughness and edge retention in small-bore cuts
• TiN finish coating increases surface hardness and reduces cutting-edge wear
• 0.18-inch minimum bore diameter enables work in very small internal diameters
• 1.5-inch maximum bore depth supports through and blind bore operations
• Right-hand cut direction compatible with standard lathe rotation
• 0.25-inch shank fits widely available boring bar holders and quick-change toolposts

Compatibility

Designed for use in standard 0.25-inch shank boring bar holders on manual lathes, engine lathes, and CNC turning centers. No specific machine model compatibility was provided by the manufacturer for this part number.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the shank firmly in a compatible 0.25-inch boring bar holder and verify tool centerline height before taking a cut. Ensure the machine spindle is at a full stop and the machine is in a safe state before changing or setting tooling. Do not exceed the rated maximum bore depth of 1.5 inches in a single pass setup without confirming adequate chip clearance.
