Sgs 07383 Circuit Board Drill Bit No. 36 Solid Carbide

Product Description

The SGS 07383 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and related small-hole applications. Built to No. 36 wire gauge size, it measures 0.1065 inches (2.71 mm) in diameter with a 1/8-inch (0.1250-inch) shank diameter and an overall length of 1.5 inches. The 130-degree four-facet point geometry reduces thrust and walking at entry, while the regular spiral with a 30-degree helix angle clears chips efficiently. The uncoated solid carbide construction delivers rigidity and heat resistance suited to tight-tolerance work. Licensed electricians, PCB technicians, and precision fabricators are the typical end users.

This drill bit is built for high-precision drilling in circuit board assemblies and similar small-diameter applications. Its material compatibility spans a wide range of substrates including fiber-reinforced polymers, plastics, aluminum, copper alloys, stainless steel, cobalt alloys, nickel, titanium, and cast iron. The tapered web configuration reinforces the bit near the point for added stability during entry. It is well suited for production environments where consistent hole diameter and clean exit geometry are required across mixed-material board stackups.

• Solid carbide construction provides rigidity and wear resistance for hard and abrasive materials
• 1/8-inch (3.18 mm) shank diameter fits standard PCB drilling chucks and precision drill presses
• Regular spiral with 30-degree helix angle and tapered web for efficient chip evacuation
• Uncoated finish - compatible with a broad range of workpiece materials without coating interaction concerns
• Right-hand cut, two-flute geometry suited to standard CNC and manual drilling setups

Compatibility

Designed for use in circuit board drilling applications with fiber-reinforced polymers, plastics, aluminum, cast iron, cobalt alloys, copper alloys, nickel, stainless steel, and titanium workpieces. Part of the SGS Series 105 circuit board drill bit line.

Installation Notes

Installation and use should be performed by qualified technicians familiar with precision drilling equipment and small-diameter carbide tooling. Secure the shank fully in a collet or chuck rated for 1/8-inch shanks before operation. Carbide is brittle - avoid side loading, flexing, or impact that can cause fracture. Power down and de-energize any associated equipment before changing tooling, and follow applicable workplace safety standards for rotating machinery.
