Sgs 07373 Circuit Board Drill Bit 2.45 Mm Solid Carbide

Product Description

The SGS 07373 is a solid carbide circuit board drill bit engineered for precision drilling in PCB fabrication and tight-tolerance machining operations. It measures 2.45 mm (0.0965 inches) in diameter with a 1/8-inch shank diameter (0.1250 inches) and an overall length of 1.5 inches. The 130-degree four-facet point geometry promotes accurate entry and minimizes walking on hard substrates. The regular spiral with a 30-degree helix angle provides efficient chip evacuation. This bit is installed by machinists, PCB fabricators, and trade technicians working with automated drilling equipment or handheld precision tools.

The SGS 07373 is suited for drilling circuit boards and a wide range of workpiece 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 heavy-duty option for applications where dimensional accuracy and clean hole walls are required. Flute length is 0.40 inches (10.16 mm), keeping the cutting zone short and rigid for small-diameter precision work in both manual and CNC setups.

• Regular spiral with 30-degree helix angle for effective chip removal
• 1/8-inch (0.1250-inch) shank diameter compatible with standard collets and chucks
• Uncoated finish suitable for a broad range of metals, plastics, and composite materials

Compatibility

Designed for use in circuit board drilling applications and compatible with workpiece materials including aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium. Fits standard 1/8-inch collets and drill chucks.

Installation Notes

This bit is installed by machinists or PCB fabrication technicians using CNC drilling equipment or precision handheld tools. Ensure the spindle and workpiece are secured before initiating any drilling operation. Use appropriate RPM and feed rate settings for the target material to avoid premature carbide wear or bit breakage. Solid carbide bits are brittle — avoid side-loading or flexing during use.
