M.a. Ford 30016600 Circuit Board Drill Bit No. 19 Solid Carbide

Product Description

The M.A. FORD 30016600 is a solid carbide circuit board drill bit engineered for precision drilling in printed circuit board fabrication and related precision machining applications. It carries a No. 19 wire gauge size with a decimal diameter of 0.1660 inches (4.22 mm) and a 118-degree drill point angle for accurate entry without walking. The fast spiral geometry and 35-degree helix angle promote efficient chip evacuation. The tapered web configuration adds rigidity while maintaining a sharp cutting edge. This bit is suited for installation by machinists, PCB fabrication technicians, and skilled trade professionals working with tight-tolerance through-hole drilling.

This drill bit is rated for use in cast iron, non-ferrous metals, steel, and plastics. Its heavy-duty grade and solid carbide construction make it appropriate for production environments where consistent hole quality and dimensional accuracy are required. The right-hand cutting direction is standard for conventional drill press and CNC spindle setups. With a 0.75-inch flute length and a compact 1.5-inch overall length, it fits standard collet and chuck systems used in PCB drilling machines and precision bench-top drill presses.

Key Features

• Solid carbide construction for superior hardness and wear resistance in precision drilling
• 118-degree drill point angle for clean, accurate entry on thin and layered materials
• Fast spiral with 35-degree helix angle for efficient chip evacuation in deep holes
• Tapered web configuration increases bit rigidity and reduces deflection
• Right-hand cutting, compatible with standard drill press and CNC spindle rotation
• Uncoated finish — suitable for applications where coating residue or contamination is a concern

Compatibility

Designed as an OEM-style precision drill bit for circuit board drilling operations; compatible with collet and chuck systems accepting a 0.1660-inch (4.22 mm) shank diameter. Suitable for use on cast iron, non-ferrous metals, steel, and plastics as listed in the manufacturer specifications.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or PCB fabrication technician familiar with precision drilling equipment. Ensure the spindle and collet are fully de-energized and at a complete stop before bit changes. Verify collet or chuck bore compatibility with the 4.22 mm shank diameter before seating the bit. Solid carbide bits are brittle — avoid side-loading, angular entry, or use in hand-held rotary tools not rated for carbide tooling.
