M.a. Ford. 30007600 Circuit Board Drill Bit Size 48 1.93mm

Product Description

The M.A. FORD. 30007600 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and light machining applications. It carries a wire gauge size of 48, which corresponds to 0.0760 inches (1.93 mm) in diameter. The 118-degree drill point angle and fast spiral flute geometry promote clean entry and efficient chip evacuation. At 1.93 mm shank diameter, this bit fits standard collet-style drill spindles used in PCB drilling equipment. Installers and machinists working in electronics manufacturing, precision machine shops, or prototyping environments will find this bit suited to demanding, small-diameter drilling tasks.

This drill bit is intended for use on cast iron, non-ferrous metals, plastics, and steel. Its fast spiral design makes it especially effective in materials that require aggressive chip removal to prevent bit binding or workpiece damage. The Series 300 classification from M.A. FORD. indicates a heavy-duty grade bit built for consistent performance in production or bench-top drilling setups. It is sold individually and is well-suited for PCB shops, precision machine shops, and electronics prototyping environments where exact hole sizing is critical.

Key Features

• Solid carbide construction delivers hardness and wear resistance for small-diameter precision drilling
• 118-degree drill point angle provides accurate, centered starts on flat and curved surfaces
• Fast spiral flute geometry promotes efficient chip evacuation and reduces heat buildup
• Tapered web configuration adds strength at the cutting tip and reduces walking on entry
• Right-hand cutting direction with 35-degree helix angle optimized for non-ferrous metals, plastics, and cast iron
• Uncoated finish maintains tight dimensional tolerances down to -0.0005 to +0.0000 inches

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for standard collet spindle drilling equipment accepting a 1.93 mm shank diameter, including PCB drilling machines and precision drill presses.

Installation Notes

This bit is installed by machinists and PCB fabrication technicians using collet-style spindle chucks compatible with the 1.93 mm shank diameter. Ensure the spindle and collet are clean and free of debris before seating the bit to maintain runout tolerances. Do not exceed the rated spindle speed for solid carbide tooling of this diameter, and inspect the cutting tip for chipping before each use. Proper feed rate and spindle speed selection per the workpiece material will extend bit life and maintain hole quality.
