Accupro ACC-HB1801500 Helical Boring Bar Solid Carbide

Product Description

The ACCUPRO ACC-HB1801500 is a helical boring bar ground from submicron solid carbide and designed for precision internal diameter boring in metal cutting applications. It features a right-hand cutting direction, a minimum bore diameter of 0.18 inches, and a maximum bore depth of 1.5 inches. The 3/16-inch shank diameter and 2.5-inch overall length make this bar well suited to small-bore work where rigidity and tool clearance are critical. The bright finish coating reduces friction at the cutting edge without altering the dimensional geometry of the bar. Machinists and tool-and-die professionals working on CNC lathes and machining centers will find this bar appropriate for tight-tolerance bores in ferrous and non-ferrous materials.

This boring bar fits applications requiring small internal bore diameters in production machining, toolroom work, and precision repair operations. Its submicron carbide grade provides the hardness and wear resistance needed for consistent performance in interrupted cuts or abrasive workpiece materials. The right-hand configuration suits standard spindle rotation setups on most CNC and manual lathes. It is a single-piece solid carbide bar without replaceable inserts, making it appropriate where setup simplicity and tool profile repeatability are priorities.

Key Features

• Submicron solid carbide construction for high hardness and edge retention
• Minimum bore diameter of 0.18 inches for small-bore internal turning
• Maximum bore depth of 1.5 inches suitable for shallow to mid-depth bores
• Right-hand cutting direction for standard spindle rotation
• Bright finish coating reduces cutting friction without dimensional impact
• 3/16-inch shank diameter with 2.5-inch overall length for compact tool holding

Compatibility

Designed as an OEM-style solid carbide helical boring bar for use in standard tool holders accepting a 3/16-inch shank diameter on CNC lathes and manual turning centers.

Installation Notes

Installation and use of this boring bar should be performed by a qualified machinist familiar with internal turning operations. Secure the shank fully in the tool holder to the recommended grip length to minimize overhang and chatter. Ensure the machine spindle is fully stopped and the lathe or machining center is powered off before changing or adjusting tooling. Do not exceed the maximum bore depth of 1.5 inches, as excessive overhang beyond the supported shank length increases deflection risk and can cause tool breakage.
