Sgs 07313 Circuit Board Drill Bit 0.9 Mm Solid Carbide

Product Description

The SGS 07313 is a solid carbide circuit board drill bit engineered for precision drilling in printed circuit boards and similar high-tolerance applications. It measures 0.9 mm (0.0354 inches) in diameter with a 130-degree four-facet point geometry that promotes accurate entry and minimizes workpiece delamination. The uncoated carbide construction delivers consistent cutting performance across a wide range of materials. With an overall length of 1.5 inches and a 1/8-inch shank diameter, this bit is sized for use in CNC drilling machines, drill presses, and high-speed spindle systems. It is most commonly installed and operated by electronics fabrication technicians and precision machining professionals.

This drill bit is suited for drilling in fiber-reinforced polymers, plastics, aluminum, copper alloy, stainless steel, cobalt alloy, nickel, cast iron, and titanium. Its regular spiral, two-flute design with a 30-degree helix angle and tapered web configuration provides efficient chip evacuation in both production and prototype circuit board drilling environments. The heavy-duty grade designation indicates suitability for demanding, repetitive drilling cycles.

Key Features

• 0.9 mm (0.0354 inches) diameter with tight tolerance of -0.0003 to +0.0000 inches for high-precision hole placement
• 130-degree four-facet point for accurate entry and reduced walking on hard substrates
• Solid carbide construction for rigidity and wear resistance in abrasive materials
• Regular spiral, two-flute design with 30-degree helix angle promotes efficient chip evacuation
• Tapered web configuration supports strength at the cutting tip
• Uncoated finish suitable for direct use on a broad range of workpiece materials including fiber-reinforced polymers and non-ferrous metals

Compatibility

Designed for use in CNC circuit board drilling machines and precision drill presses accepting a 1/8-inch shank. Compatible workpiece materials include aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium as stated by the manufacturer.

Installation Notes

This bit is installed and operated by machining technicians or electronics fabrication professionals. Ensure the spindle and work-holding fixture are fully secured and the machine is powered down before changing bits. Use appropriate RPM and feed rate settings for the target material and bit diameter to avoid breakage on this small-diameter tool. Eye protection and applicable shop safety protocols should be observed during operation.
