Micro 100 HBBC-100750-004 Solid Carbide Boring Bar

Product Description

The MICRO 100 HBBC-100750-004 is a solid carbide boring bar designed for precision internal boring operations in small-diameter applications. With a minimum bore diameter of 0.0950 inches and a maximum bore depth of 0.75 inches, this tool handles tight-tolerance work where rigidity and dimensional accuracy are critical. The 1/8 inch shank diameter keeps the tool compact for use in small bores, while the solid carbide construction provides the hardness and wear resistance needed for consistent performance across ferrous and non-ferrous materials. Machinists and tool and die professionals rely on this style of boring bar for close-tolerance finish passes in manual or CNC turning and boring operations.

This boring bar is suited for small-bore internal machining tasks on lathes, machining centers, and dedicated boring machines in job shop, production, and toolroom environments. The right-hand cutting direction makes it compatible with standard spindle rotation setups. The 0.0040 inch corner radius supports fine surface finishes in precision bore work. With an overall length of 1.5 inches, the tool fits compact toolholding setups where minimal overhang is required for chatter-free cuts.

Key Features

• Minimum bore diameter of 0.0950 inches for small-diameter internal machining
• Maximum bore depth of 0.75 inches suits shallow to mid-depth bore applications
• Solid carbide construction delivers hardness, rigidity, and extended tool life
• Right-hand cutting direction for standard spindle rotation compatibility
• 0.0040 inch corner radius for controlled surface finish on finish passes
• 1/8 inch shank diameter fits compact toolholding systems

Compatibility

Designed as an OEM-style solid carbide boring bar for use in toolholders and boring heads that accept a 1/8 inch round shank in manual and CNC lathe or boring machine setups.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Ensure the machine spindle is fully stopped and the tool changer or turret is in a safe indexed position before mounting or removing the boring bar. Secure the shank firmly in the toolholder to the minimum recommended engagement depth to reduce deflection and chatter. Inspect the cutting edge for chips or wear before each use, as solid carbide tooling can fracture if used with damaged edges.
