Micro 100 BB-1801500S Boring Bar Solid Carbide Right Hand

Product Description

The MICRO 100 BB-1801500S is a solid carbide boring bar designed for precision internal diameter machining on lathes and turning centers. 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 finish and semi-finish operations where rigidity and dimensional accuracy are critical. The right-hand cutting direction follows standard orientation for most CNC and manual turning setups. With an overall length of 2.5 inches and a 0.25-inch shank diameter, this bar is compact and fits common small-bore toolholders without modification. Machinists and tool-and-die professionals typically select solid carbide boring bars over steel-shanked alternatives when chatter control and surface finish consistency are priorities in tight-tolerance work.

The BB-1801500S is suited for small-bore internal turning operations in job shop, production, and toolroom environments. It is appropriate for use on CNC lathes, turret lathes, and manual engine lathes where a 0.25-inch shank toolholder is available. Right-hand cut geometry is standard for conventional OD turning setups adapted to ID boring. The compact overall length and minimum bore diameter make this bar a practical choice for workpieces with shallow, narrow bores that require precise wall clearance and consistent chip evacuation.

Key Features

• Solid carbide construction provides superior rigidity and vibration damping compared to steel-shanked boring bars
• Minimum bore diameter of 0.18 inches enables access to small, tight-tolerance bores
• Maximum bore depth of 1.5 inches suits typical shallow-bore finishing applications
• Right-hand cutting direction compatible with standard CNC and manual lathe setups
• 0.25-inch shank diameter fits common small-bore toolholders
• Compact 2.5-inch overall length reduces overhang and improves stability

Compatibility

Designed for use with toolholders accepting a 0.25-inch shank boring bar in CNC and manual turning applications requiring right-hand cut geometry and a minimum bore entry of 0.18 inches.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practice. Secure the shank fully within the toolholder to the recommended minimum clamping depth to reduce overhang and deflection. Power down and lock out the machine spindle before changing or adjusting tooling. Verify bore diameter clearance against the workpiece drawing before beginning the cut to avoid tool or part damage.
