Scientific Cutting Tools B080300A Boring Bar Solid Carbide

Product Description

The SCIENTIFIC CUTTING TOOLS B080300A is a solid carbide boring bar engineered for small-diameter internal turning operations on CNC lathes and machining centers. Built from submicron-grade carbide and finished with an AlTiN+ coating, this bar handles tight-tolerance bores starting at 0.08 inches minimum bore diameter with a maximum bore depth of 0.3 inches. The right-hand cutting direction suits standard spindle setups. The 0.125-inch shank diameter and 1.5-inch overall length make it well-suited for compact toolholders and live tooling on small-part turning machines. Machinists and CNC operators working in medical, aerospace, or precision instrument applications will find this bar a reliable choice for finishing and semi-finishing passes in confined bore geometries.

This boring bar is intended for precision internal boring in small-diameter workpieces where rigidity and concentricity are critical. The submicron carbide substrate resists chipping and wear under high cutting speeds in ferrous and non-ferrous materials. The AlTiN+ coating provides thermal resistance and extended tool life in dry or minimum-quantity lubrication machining environments. It fits standard 1/8-inch shank boring bar holders and is sold individually.

Key Features

• Submicron solid carbide substrate for high rigidity and wear resistance in small-bore applications
• AlTiN+ finish coating for elevated thermal resistance and extended cutting life
• Minimum bore diameter of 0.08 inches enables work in very small internal features
• Maximum bore depth of 0.3 inches suits through and blind-bore finishing passes
• Right-hand cutting direction for conventional CNC lathe and machining center spindle orientation
• Compact 0.125-inch shank diameter and 1.5-inch overall length for use in tight tooling envelopes

Compatibility

Designed for use in standard 1/8-inch shank boring bar holders on CNC lathes and machining centers requiring right-hand internal turning capability at small bore diameters.

Installation Notes

Installation is performed by qualified CNC machinists or tooling setup technicians. Secure the shank fully within the boring bar holder to the manufacturer-specified clamping depth before running the spindle. Ensure the machine spindle is fully stopped and the control is in a safe state before changing or indexing tooling. Verify bore alignment and runout with an indicator before taking finish passes to protect both the tool and the workpiece.
