M.a. Ford 30503700 Micro Drill Bit Wire 63 Solid Carbide

Product Description

The M.A. FORD 30503700 is a solid carbide micro drill bit designed for precision drilling in demanding materials. Built to Series 305 specifications, it carries a wire gauge size of 63, corresponding to a decimal diameter of 0.0370 inches. The 135-degree split-point geometry reduces walking at entry and lowers thrust requirements in hard materials. Overall length is 1.5 inches with a flute length of 0.4000 inches. The 1/8-inch straight-cylindrical shank seats securely in standard collet chucks and drill presses. This bit is suited for production and toolroom environments where tight-tolerance micro holes are required in ferrous and non-ferrous workpieces.

The 30503700 is intended for use on cast iron, hardened steel, stainless steel, carbon steel, and non-ferrous metals. The two-flute spiral design promotes chip evacuation in these materials. Typical install scenarios include CNC machining centers, benchtop drill presses, and hand-held precision drilling fixtures where a 1/8-inch shank toolholder is available. This bit is a common choice for machinists, toolmakers, and precision fabricators working in job shops or maintenance environments requiring small-diameter through-holes or pilot holes.

Key Features

• Wire gauge size 63 (0.0370 inches) for fine-tolerance micro drilling
• 135-degree point angle for self-centering entry and reduced thrust
• Solid carbide construction for rigidity and wear resistance in hard materials
• Two-flute spiral geometry for efficient chip evacuation
• 1/8-inch straight-cylindrical shank for compatibility with standard collet systems
• Manufactured to ISO 9001:2015 quality standards

Compatibility

Designed as an OEM-style replacement or direct-use micro drill bit for applications requiring a wire gauge size 63 diameter with a 1/8-inch straight-cylindrical shank in standard collet chucks or drill press toolholders.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or toolroom technicians familiar with small-diameter carbide tooling. Always secure the shank fully within the collet or chuck before operation and verify runout is within acceptable limits, as carbide micro drills are brittle and susceptible to breakage from lateral loading. Power down and de-energize the spindle before tool changes. Avoid side loading and use appropriate speeds and feeds for the workpiece material to prevent premature tool failure.
