Sgs 07308 Circuit Board Drill Bit 0.95mm Solid Carbide

Product Description

The SGS 07308 is a solid carbide circuit board drill bit engineered for precision drilling in printed circuit boards and other tight-tolerance applications. Measuring 0.95 mm (0.0374 inches) in diameter with a 1/8-inch (3.18 mm) shank, this bit features a 130-degree four-facet point that reduces walking and produces clean entry holes in hard and brittle substrates. The regular spiral with a 30-degree helix angle clears chips efficiently during high-speed drilling operations. With a heavy-duty grade rating and an overall length of 1.5 inches (38.10 mm), the 07308 is built for consistent, repeatable performance in production and repair environments.

This drill bit is suited for use on a wide range of materials including fiber-reinforced polymers, plastics, aluminum, copper alloy, cast iron, stainless steel, cobalt alloy, nickel, and titanium. The uncoated solid carbide construction makes it appropriate for both dry drilling and light coolant applications on PCB assemblies, electronics manufacturing setups, and precision fabrication workflows. It is typically used by electronics technicians, precision machinists, and fabricators working with small-diameter hole requirements.

Key Features

• 0.95 mm (0.0374 inches) diameter with a diameter tolerance of -0.0003 to +0.0000 inches for tight-tolerance hole requirements
• 130-degree four-facet point reduces bit walking and produces clean, accurate entry holes
• Solid carbide construction delivers rigidity and wear resistance in abrasive and hard materials
• 1/8-inch (3.18 mm) shank diameter compatible with standard drill chucks and collets
• Regular spiral with 30-degree helix angle promotes efficient chip evacuation
• Tapered web configuration adds core strength for demanding drilling conditions
• Right-hand cutting direction; uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed for use with standard 1/8-inch collet or chuck systems. Suitable for drilling fiber-reinforced polymers, plastics, aluminum, cast iron, copper alloy, stainless steel, cobalt alloy, nickel, and titanium workpieces.

Installation Notes

This bit should be installed in a precision drill press, CNC drilling machine, or router with a compatible 1/8-inch collet or chuck. Power down and secure the spindle before changing bits. Use appropriate spindle speeds for the workpiece material and bit diameter — excessively low speeds can cause premature wear on carbide tooling. Handle solid carbide bits carefully to avoid chipping; do not drop or clamp on the fluted section.
