Accupro ACC-HB4801500 Helical Boring Bar Solid Carbide

Product Description

The ACCUPRO ACC-HB4801500 is a helical boring bar machined from submicron-grade solid carbide with a bright finish. It is designed for internal boring operations requiring tight tolerances and consistent chip evacuation. The helical flute geometry promotes smooth cutting action and reduces chatter at depth. With a minimum bore diameter of 0.48 inches and a maximum bore depth of 1.5 inches, this bar suits a wide range of small-bore finish and semi-finish passes. The 0.5-inch shank diameter and 3-inch overall length make it compatible with standard boring tool holders on CNC lathes and machining centers. Machinists and toolroom technicians are the primary users of this tool.

This boring bar is suited for precision internal turning on CNC lathes, turning centers, and horizontal machining centers. It handles ferrous and non-ferrous materials where a fine surface finish and close dimensional control are required. The right-hand cutting direction follows the standard rotation convention for most CNC lathe setups. Typical applications include bore finishing in production environments, toolroom work, and prototype machining where submicron carbide grade provides wear resistance and edge retention at elevated cutting speeds.

Key Features

• Submicron solid carbide construction for extended tool life and edge stability
• Helical boring bar type promotes efficient chip flow and reduced cutting forces
• Bright finish coating — no coating buildup that could affect dimensional tolerances
• Right-hand cutting direction for standard CNC lathe and machining center setups
• 0.5-inch shank diameter fits common boring bar holders and quick-change tooling systems
• Compact 3-inch overall length suits close-clearance setups

Compatibility

Designed as an OEM-style replacement or direct tooling addition for standard 0.5-inch boring bar holders used on CNC lathes and machining centers requiring a right-hand helical boring bar.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank firmly in a matched-diameter boring bar holder and verify tool overhang does not exceed recommended length-to-diameter ratios to minimize deflection. Confirm spindle is fully stopped and machine is in a safe state before mounting or removing the tool. Follow the machine tool manufacturer guidelines and applicable shop safety standards when setting cutting parameters.
