Sgs 07394 Circuit Board Drill Bit 3mm Solid Carbide

Product Description

The SGS 07394 is a solid carbide circuit board drill bit engineered for precision drilling in printed circuit boards and other demanding materials. The bit measures 3 mm (0.1181 inches) in diameter with a 1/8-inch (3.18 mm) shank diameter and an overall length of 1-1/2 inches (38.10 mm). A 130-degree four-facet point geometry delivers accurate entry and reduces walking on hard substrates. With a 30-degree helix angle and regular spiral flute design, the bit provides controlled chip evacuation and consistent cutting performance. This is a heavy-duty grade tool built for professional and production-level use.

The SGS 07394 is suited for drilling operations in electronics manufacturing, PCB fabrication, and precision machining environments. Its right-hand cut and tapered web configuration make it effective across a range of materials including aluminum, cast iron, copper alloy, stainless steel, titanium, cobalt alloy, nickel, plastics, and fiber-reinforced polymers. It is a practical choice for machinists, electronics technicians, and shop professionals who require tight-tolerance drilling in fine-diameter applications.

Key Features

• 3 mm diameter with diameter tolerance of -0.0003 to +0.0000 inches for precision fitment
• 130-degree four-facet point for accurate, low-thrust entry
• Solid carbide construction for rigidity and wear resistance
• 30-degree helix angle with regular spiral for efficient chip removal
• Uncoated finish suitable for a broad range of workpiece materials
• Heavy-duty grade with tapered web for added strength at the cutting edge

Compatibility

Designed for use with standard 1/8-inch shank collets and compatible chucks across CNC drilling machines, drill presses, and precision hand tools used in PCB and precision machining applications.

Installation Notes

This bit is intended for installation by machinists or electronics fabrication professionals familiar with precision drilling equipment. Ensure the collet or chuck is rated for 1/8-inch shank tooling and is properly tightened before operation. Follow machine manufacturer guidelines for spindle speed settings appropriate to the workpiece material. Inspect the bit for chipping or wear before each use, as carbide tooling can fracture if run in worn or misaligned setups.
