Scientific Cutting Tools B180750A Boring Bar Solid Carbide

Product Description

The SCIENTIFIC CUTTING TOOLS B180750A is a solid carbide boring bar engineered for precision internal turning and bore finishing operations on CNC lathes and manual turning centers. Built from submicron-grade solid carbide with an AlTiN+ finish coating, this bar delivers high wear resistance and thermal stability in demanding cutting environments. It features a right-hand cutting direction, a minimum bore diameter of 0.18 inches, a maximum bore depth of 0.75 inches, and a 1/4-inch shank diameter. Overall length is 2.5 inches. Machinists and toolroom technicians select this bar when tight-tolerance bore work requires rigidity and a fine surface finish on small-diameter holes.

This boring bar is suited for small-bore applications in ferrous and non-ferrous materials where dimensional accuracy and finish quality are critical. Typical use cases include production turning operations on CNC lathes, toolroom work, and prototype machining. The compact 0.18-inch minimum bore capability makes it a strong fit for precision components with restricted bore entry diameters. The AlTiN+ coating extends tool life in higher-speed or interrupted-cut scenarios.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance in small-bore applications
• AlTiN+ finish coating improves thermal resistance and extends cutting life
• Right-hand cutting direction for standard CNC lathe and manual turning setups
• 0.18-inch minimum bore diameter enables precision work on restricted-entry bores
• 0.75-inch maximum bore depth with a 1/4-inch shank diameter for stable toolholding
• 2.5-inch overall length suits compact tooling setups and tight-clearance applications

Compatibility

Designed for use in standard 1/4-inch boring bar holders and compatible tooling systems on CNC and manual turning centers requiring a right-hand, small-diameter boring bar.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the 1/4-inch shank firmly in the boring bar holder to the holder manufacturer's specified clamping torque range before engaging the spindle. Power down and lock out the machine before changing or adjusting tooling. Avoid overhang beyond the recommended depth-to-diameter ratio to minimize vibration and deflection during cutting.
