M.a. Ford. 30014700 Circuit Board Drill Bit Size 26

Product Description

The M.A. FORD. 30014700 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and related electronic assembly work. Built to Series 300 heavy-duty standards, it features a 118-degree drill point angle and a fast spiral with a 35-degree helix angle that promotes efficient chip evacuation. The wire gauge size is 26, with a decimal inch diameter of 0.1470 inches (3.73 mm). Flute length is 0.75 inches and overall length is 1.5 inches. The bit is uncoated and ground for right-hand cutting. Licensed electricians, PCB fabricators, and precision machine operators are the primary installers.

This drill bit is suited for through-hole drilling in circuit boards as well as light-duty machining of cast iron, non-ferrous metals, and plastics. The fast spiral geometry keeps chip load manageable in these materials, reducing heat buildup and minimizing the risk of workpiece damage. It is a single-piece solid carbide construction, which provides the rigidity needed for small-diameter, high-precision holes. It fits standard CNC drill spindles and manual drill presses that accept a 0.1470-inch (3.73 mm) shank diameter. Both production shops and bench-level technicians use this bit for consistent, repeatable hole geometry.

Key Features

• Solid carbide construction for rigidity and extended tool life in precision drilling
• 118-degree drill point angle for accurate hole entry with minimal walking
• Fast spiral with 35-degree helix angle promotes chip evacuation in circuit board materials
• Tapered web configuration for added strength at the cutting tip
• Uncoated finish suitable for cast iron, non-ferrous metals, and plastics
• Right-hand cutting direction, compatible with standard CNC and manual drill spindles

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide drill bit for applications requiring a wire gauge size 26 (0.1470 inch) diameter bit with a 3.73 mm shank on CNC or manual drilling equipment used in circuit board and light machining operations.

Installation Notes

Installation and use should be performed by qualified machinists, PCB fabricators, or trained technicians. Ensure the drill spindle and chuck are powered down and fully stopped before inserting or removing the bit. Verify chuck or collet size matches the 3.73 mm shank diameter before securing the tool. Do not exceed the rated RPM or feed rate for the workpiece material, as solid carbide bits are brittle and can fracture under excessive lateral load.
