Accupro ACC-TBB625 Boring Bar Right Hand Micrograin

Product Description

The ACCUPRO ACC-TBB625 is a solid micrograin carbide boring bar designed for internal diameter boring operations on metal lathes and machining centers. It features a 5/8-inch shank diameter and an overall length of 8 inches, with a minimum bore diameter of 0.795 inches and a maximum bore depth of 4 inches. The bright finish coating reduces friction and aids in chip evacuation. This bar is suited for machinists and toolroom professionals who need consistent, repeatable bore geometry in ferrous and non-ferrous materials.

The ACC-TBB625 is intended for use in manual lathes, CNC turning centers, and boring mills where right-hand cutting orientation is required. It fits standard tool holders accepting a 5/8-inch round shank. Typical applications include finish boring of through-holes and blind bores in production and job-shop environments. The micrograin carbide construction supports higher cutting speeds and finer finishes compared to standard carbide grades.

Key Features

• Micrograin carbide construction for improved wear resistance and surface finish capability
• Right-hand cutting direction for standard lathe and turning center setups
• Minimum bore diameter of 0.795 inches supports a range of bore sizes
• Maximum bore depth of 4 inches accommodates deeper cavity work
• Bright finish coating reduces built-up edge and aids chip flow
• 5/8-inch shank diameter fits common tool holders and boring bar holders

Compatibility

Designed for use in tool holders and boring bar holders accepting a 5/8-inch round shank, suitable for right-hand boring operations on manual and CNC turning equipment.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Secure the shank firmly in the boring bar holder, ensuring adequate overhang is minimized to reduce vibration and chatter. Power down and lock out the spindle before mounting or adjusting the tool. Always verify cutting direction and tool clearance before initiating a cut.
