M.a. Ford 30016950 Circuit Board Drill Bit Size 18

Product Description

The M.A. FORD 30016950 is a solid carbide, fast spiral circuit board drill bit designed for precision drilling in printed circuit board and light industrial applications. Built to Series 300 specifications, this bit carries a wire gauge size of 18, translating to a decimal diameter of 0.1695 inches (4.31 mm). The 118-degree drill point angle and tapered web configuration promote clean entry and efficient chip evacuation. With a 35-degree helix angle and right-hand cutting direction, it is suited for consistent, repeatable hole quality in production and repair environments. Licensed electricians, PCB technicians, and precision machine operators are the typical end users.

This drill bit is intended for use on cast iron, non-ferrous metals, plastics, and steel workpieces. The fast spiral flute geometry helps clear chips quickly during high-speed drilling operations, reducing heat buildup and extending tool life. A flute length of 0.75 inches (19.05 mm) and an overall length of 1.5 inches (38.10 mm) keep the bit rigid for close-tolerance work in tight board layouts or small-part fixtures. The heavy-duty grade designation reflects its construction for repeated use in demanding shop and field conditions.

Key Features

• Solid carbide construction for high wear resistance and dimensional stability
• Wire size 18 (0.1695 inches / 4.31 mm) diameter for precise hole sizing
• 118-degree drill point angle with tapered web for accurate starting and reduced walking
• Fast spiral, 35-degree helix angle promotes efficient chip evacuation
• Right-hand cutting direction, compatible with standard drill press and CNC spindle setups
• Uncoated finish suitable for use across cast iron, non-ferrous metals, plastics, and steel

Compatibility

Designed as an OEM-style replacement or production-use solid carbide circuit board drill bit for applications involving cast iron, non-ferrous metals, plastics, and steel workpieces requiring a wire gauge size 18 hole.

Installation Notes

Install and removal should be performed with the machine powered down and the spindle fully stopped. Secure the bit firmly in a compatible collet or chuck rated for the 4.31 mm shank diameter before operation. Follow applicable shop safety procedures and machine manufacturer guidelines for speed and feed settings appropriate to the workpiece material. Inspect the cutting edges for chipping or wear before each use, as carbide tooling can fracture if run at incorrect parameters or if the bit contacts a workpiece while spinning up.
