Micro 100 TBB-750 Boring Bar 0.935 in Right Hand Carbide

Product Description

The MICRO 100 TBB-750 is a brazed solid carbide boring bar designed for precision internal diameter machining on lathes and boring mills. It features a minimum bore diameter of 0.935 inches, a 0.75-inch shank diameter, and an overall length of 9 inches. The right-hand cutting direction suits standard toolpost and turret setups. Brazed solid carbide construction delivers higher rigidity and wear resistance compared to indexable tooling in small-bore applications, making it a go-to choice for machinists holding tight tolerances on finish passes.

This boring bar is suited for job shops, production floors, and toolroom environments where consistent internal diameter work is required. It is appropriate for use in ferrous and non-ferrous materials where a solid carbide tool provides the necessary stiffness and edge retention at small bore diameters. The 9-inch overall length allows reach into deeper bores without excessive overhang relative to the 0.75-inch shank. Machinists running manual or CNC lathes will find the TBB-750 a practical fit for finish boring operations.

Key Features

• Brazed solid carbide construction for high rigidity and wear resistance in small-bore finish work
• Minimum bore diameter of 0.935 inches suits a range of internal diameter applications
• Right-hand cutting direction compatible with standard toolpost and turret configurations
• 0.75-inch shank diameter for secure tool holding with common boring bar holders
• 9-inch overall length provides reach into deeper bores while maintaining shank stiffness

Compatibility

Designed as an OEM-style solid carbide boring bar for use in standard lathe and boring mill toolholders accepting a 0.75-inch shank diameter with right-hand cutting orientation.

Installation Notes

Installation is performed by qualified machinists following standard lathe toolsetting procedures. Power down and lock out the machine before securing the bar in the toolholder. Ensure the shank is fully seated and clamped to the toolholder manufacturer's specified engagement length to minimize deflection. Verify tool centerline height before commencing any boring operation.
