Accupro ACC-TBB750 Boring Bar 0.935 in Min Bore Micrograin

Product Description

The ACCUPRO ACC-TBB750 is a solid boring bar designed for internal diameter machining on lathes and boring mills. Built from micrograin carbide, it delivers consistent edge retention and surface finish quality across a range of ferrous and non-ferrous materials. The bar features a right-hand cutting direction and accepts a minimum bore diameter of 0.935 inches, making it suitable for close-tolerance bore work. With a 0.75-inch shank diameter and a 9-inch overall length, it mounts securely in standard tool holders. Machinists and toolroom technicians use this bar for production and job-shop applications where dimensional accuracy is critical.

The ACC-TBB750 is suited for CNC turning centers, manual lathes, and horizontal boring mills requiring a rigid, high-performance boring bar. A maximum bore depth of 4.5 inches allows it to reach deep bores without excessive overhang. The bright finish coating reduces friction and aids chip evacuation. This bar is a practical choice for shops machining hydraulic cylinders, pump housings, valve bodies, and similar components that demand repeatable bore geometry and tight tolerances.

Key Features

• Micrograin carbide construction for superior wear resistance and edge retention
• Right-hand cutting direction for standard CNC and manual lathe setups
• Minimum bore diameter of 0.935 inches for close-tolerance internal work
• Maximum bore depth of 4.5 inches to handle deeper bore applications
• Bright finish coating reduces friction and promotes chip flow
• 0.75-inch shank diameter fits standard toolholder sizes

Compatibility

Designed as a standard shank boring bar compatible with tool holders accepting a 0.75-inch round shank, typical of CNC turning centers and manual lathes used in general machining applications.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine before mounting or removing the bar from the tool holder. Ensure the shank is fully seated and clamped to the tool holder manufacturer's specifications to minimize runout and chatter. Verify bore depth and diameter setup with a test cut before running production.
