Sgs 07328 Circuit Board Drill Bit Size 56 Solid Carbide

Product Description

The SGS 07328 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit boards and other tight-tolerance applications. It carries a wire gauge size of 56, which corresponds to a decimal diameter of 0.0465 inches (1.18 mm), making it appropriate for fine-pitch work where accuracy is critical. The 130-degree four-facet point geometry reduces thrust and improves hole entry accuracy. The right-hand, regular spiral flute design with a 30-degree helix angle helps clear chips efficiently. This bit is installed by electronics fabricators, precision machinists, and trade professionals working on control boards and instrumentation panels.

The SGS 07328 suits drilling operations in a wide range of materials including aluminum, cast iron, copper alloy, stainless steel, titanium, cobalt alloy, nickel, plastics, and fiber-reinforced polymers. The uncoated solid carbide construction makes it a reliable choice for PCB drilling and other applications requiring tight diameter tolerance and consistent hole quality. The 1/8-inch shank diameter fits standard collet chucks and drill press spindles commonly used in light machining and electronics assembly environments.

Key Features

• Wire gauge size 56 with decimal diameter of 0.0465 inches for fine-pitch drilling
• 130-degree four-facet point reduces thrust and improves hole entry precision
• Solid carbide construction for wear resistance in abrasive and hard materials
• Uncoated finish maintains consistent cutting geometry without coating buildup
• 30-degree helix angle with regular spiral for efficient chip evacuation
• Tapered web configuration supports strength at the cutting tip

Compatibility

Designed for use in standard 1/8-inch collet chucks and drill press spindles; compatible with drilling operations in alloy steel, titanium, aluminum, cast iron, copper alloy, nickel, cobalt alloy, stainless steel, plastics, and fiber-reinforced polymers as stated in manufacturer material application data.

Installation Notes

This bit is typically installed and operated by machinists or electronics fabricators using a CNC drill press, bench drill, or hand drill with a compatible collet or chuck rated for 1/8-inch shanks. Ensure the spindle and workpiece are properly secured before drilling to prevent bit deflection or breakage. Carbide bits are brittle - avoid lateral loading or side pressure during operation. Follow applicable shop safety practices and machine manufacturer guidelines for speed and feed rates appropriate to the workpiece material.
