Sgs 07356 Circuit Board Drill Bit No. 47 Solid Carbide

Product Description

The SGS 07356 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and tight-tolerance machining applications. Ground to a 130-degree point angle with a right-hand cut and regular spiral flute, this bit delivers clean, accurate entry holes in a wide range of materials. The wire gauge size is No. 47, corresponding to 0.0785 inches (1.99 mm) in decimal. Overall length is 1.5 inches with a 1/8-inch shank diameter. The bright, uncoated finish is suitable for use across metals, plastics, and composites. Licensed electricians, PCB technicians, and precision machinists are the primary users of this tool.

This drill bit is built for applications where hole diameter accuracy is critical. The No. 47 wire size makes it a standard choice for through-hole PCB work, small pilot holes, and precision component mounting in electronics manufacturing and repair. The tapered web configuration helps reduce thrust and walking at entry. Compatible material applications include aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced plastic, nickel, plastic, stainless steel, and titanium, making this bit versatile across electronic and light machining environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision drilling
• 130-degree point angle optimized for circuit board and multi-material entry
• No. 47 wire size - 0.0785 inches (1.99 mm) decimal diameter
• 1/8-inch shank diameter fits standard collets and drill chucks
• Tapered web reduces thrust and minimizes drill walk at hole entry
• Right-hand cut, regular spiral for consistent chip evacuation
• Bright uncoated finish - no coating buildup affecting hole diameter

Compatibility

Designed for use in materials including aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced plastic, nickel, plastic, stainless steel, and titanium. Fits any standard 1/8-inch collet or drill chuck used in PCB drilling machines, CNC drilling centers, and handheld precision drill presses.

Installation Notes

This bit is installed by machinists, PCB fabrication technicians, or electronics repair professionals using a compatible 1/8-inch collet or chuck. Secure the shank fully before operation and verify runout is within tolerance before drilling critical holes. Solid carbide is brittle - avoid side loading or flexing the bit during use. Always power down the machine and secure the workpiece before changing or inspecting tooling.
