Sgs 07324 Circuit Board Drill Bit Size 57 Solid Carbide

Product Description

The SGS 07324 is a solid carbide circuit board drill bit in wire gauge size 57, with a decimal diameter of 0.0430 inches (1.09 mm). It features a 130-degree four-facet point for accurate entry and reduced walking on hard or composite substrates. The 1/8-inch shank diameter measures 0.1250 inches, and the overall length is 1.5 inches. The regular spiral geometry and 30-degree helix angle support efficient chip evacuation in shallow-depth PCB and precision drilling applications. The uncoated carbide construction is suited for use by machinists, electronics fabricators, and trade technicians drilling into tight-tolerance circuit board materials.

This drill bit is designed for drilling printed circuit boards and other precision assemblies where small-diameter, high-accuracy holes are required. Compatible material applications include aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium. The tapered web configuration and two-flute design make it appropriate for production or bench drilling operations where consistent hole geometry is critical.

Key Features

• Wire gauge size 57 with 0.0430-inch decimal diameter for tight-tolerance PCB drilling
• 130-degree four-facet point reduces drill walk and improves entry accuracy
• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 1/8-inch (0.1250-inch) shank diameter fits standard collets and drill chucks
• Regular spiral with 30-degree helix angle promotes chip clearing in short-flute applications
• Uncoated finish suitable for a broad range of workpiece materials including plastics and non-ferrous metals

Compatibility

Compatible with aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium workpiece materials per manufacturer specification.

Installation Notes

This bit is installed by machinists or electronics technicians using a standard drill press, CNC drilling machine, or precision hand drill with a compatible collet or chuck accepting a 1/8-inch shank. Ensure the workpiece is securely fixtured before drilling to prevent deflection on small-diameter holes. Run at appropriate spindle speeds for the workpiece material; carbide tooling requires stable, vibration-free setups to avoid chipping. Inspect the cutting edge before each use and replace if chipping or wear is visible.
