M.a. Ford. 30014950 Circuit Board Drill Bit 3.80mm

Product Description

The M.A. FORD. 30014950 is a solid carbide, fast-spiral circuit board drill bit engineered for precision drilling in printed circuit board fabrication and similar high-accuracy applications. It carries a No. 25 wire gauge size with a decimal diameter of 0.1495 inches (3.80 mm) and a 118-degree drill point angle. The tapered web and 35-degree helix angle promote efficient chip evacuation and reduce heat buildup during high-cycle operation. With a heavy-duty grade designation and uncoated solid carbide construction, this bit delivers consistent hole geometry and extended tool life in production environments. HVAC, electrical, and light fabrication shops will find it suitable for tight-tolerance drilling tasks.

This drill bit is rated for use in cast iron, non-ferrous metals, plastics, and steel. The fast spiral geometry makes it particularly effective in softer non-ferrous materials and plastics where chip clearing is critical to hole quality. The 3.80 mm straight shank fits standard drill chucks and CNC spindles used in circuit board and light-duty machining operations. It is sold individually and suits both production-line and bench-service applications where a reliable, single-piece replacement bit is needed.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-cycle drilling
• No. 25 wire size, 0.1495 inches (3.80 mm) diameter with tight tolerance of -0.0005 to +0.0000 inches
• 118-degree drill point angle with tapered web for accurate entry and reduced walking
• 35-degree fast helix angle promotes aggressive chip evacuation in plastics and non-ferrous metals
• Right-hand cutting direction, 2-flute design for clean, consistent hole finish
• Uncoated finish suitable for applications where coating adhesion or contamination is a concern

Compatibility

Designed as an OEM-style replacement or production-use drill bit for standard 3.80 mm drill chucks and CNC spindle collets used in circuit board drilling, light machining, and fabrication applications across cast iron, non-ferrous metal, plastic, and steel workpieces.

Installation Notes

Installation and use should be performed by a qualified machinist or technician familiar with drill press, hand drill, or CNC spindle operation. Ensure the chuck or collet is fully tightened and the workpiece is securely fixtured before initiating a cut. Solid carbide tooling is brittle compared to high-speed steel — avoid side loading, interrupted cuts without proper feed rate adjustment, and dropping the bit on hard surfaces. Follow the machine manufacturer's recommended feed and speed parameters for the workpiece material.
