M.a. Ford 30003120 Circuit Board Drill Bit 1/32 Inch

Product Description

The M.A. FORD 30003120 is a solid carbide fast-spiral circuit board drill bit designed for precision drilling in printed circuit boards and other tight-tolerance applications. It carries a 1/32 inch (0.0312 inch) drill diameter with a 118-degree drill point angle and a tapered web configuration. The fast spiral geometry, combined with a 35-degree helix angle and two flutes, promotes efficient chip evacuation during high-speed drilling operations. Licensed machinists, PCB fabricators, and precision shop technicians are the primary installers of this tool.

This bit is suited for drilling through cast iron, non-ferrous metals, plastics, and steel in both production and low-volume environments. The 1/32 inch shank diameter matches the drill diameter, making it compatible with standard precision collet chucks and drill presses configured for small-diameter tooling. With a 1/2 inch flute length and 1-1/2 inch overall length, it fits in benchtop and CNC drilling stations commonly used in circuit board and precision machining work. It is sold individually.

Key Features

• Solid carbide construction for rigidity and wear resistance in fine-diameter drilling
• 118-degree drill point angle with tapered web for accurate hole entry
• Fast spiral, 35-degree helix angle for efficient chip removal
• Right-hand cutting direction, two-flute design
• Uncoated finish suited for dry or lubricated drilling in PCB and metalworking applications
• Heavy-duty grade rated for cast iron, non-ferrous metals, plastics, and steel

Compatibility

Designed as an OEM-style replacement or direct application tool for precision drilling operations requiring a 1/32 inch solid carbide circuit board drill bit with a fast spiral geometry.

Installation Notes

This bit is installed by machinists and precision drilling technicians using collet-type tool holders rated for small-diameter tooling. Ensure the spindle and collet are clean and properly seated before securing the shank to prevent runout. Always confirm spindle speed is appropriate for the bit diameter and workpiece material before beginning the cut. Inspect the cutting edges before each use, as solid carbide bits at this diameter are brittle and susceptible to breakage if mishandled or run at incorrect feeds and speeds.
