M.a. Ford. 30004920A 1.25mm Circuit Board Drill Bit

Product Description

The M.A. FORD. 30004920A is a solid carbide fast spiral drill bit engineered for precision circuit board drilling and small-hole machining. At 1.25mm (0.0492 inches) in diameter, it features a 118-degree drill point angle and a right-hand cutting direction. The fast spiral geometry and 35-degree helix angle promote efficient chip evacuation, reducing heat buildup and improving hole quality in demanding materials. The tapered web configuration adds rigidity at the cutting tip. This bit is used by machinists, electronics manufacturers, and CNC operators working with tight-tolerance, small-diameter holes.

This drill bit is suited for use in circuit board fabrication, light-gauge metal work, and precision machining applications. It is rated for use in cast iron, non-ferrous metals, and plastics, making it a versatile choice for production and repair environments. The 16mm flute length and 38mm overall length (approximately 0.630 inches and 1.496 inches respectively) fit standard collet and chuck setups used in CNC drilling machines and precision drill presses. Series 300 designates this as part of M.A. FORD.s dedicated small-diameter carbide drill line.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 1.25mm diameter with a 118-degree drill point for precise entry and reduced walking
• Fast spiral with 35-degree helix angle for effective chip removal and reduced heat
• Tapered web configuration adds tip strength during high-speed drilling
• Right-hand cutting direction, compatible with standard CNC and manual drill setups
• Coated finish for extended tool life in production runs

Compatibility

Designed as an OEM-style replacement or production-use drill bit for CNC drilling machines and precision drill presses accepting small-diameter collet or chuck tooling. Rated for cast iron, non-ferrous metals, and plastics per manufacturer specifications.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators familiar with small-diameter carbide tooling. Ensure the spindle and collet are clean and properly torqued before use, as runout will cause premature breakage in bits at this diameter. Always confirm correct RPM and feed rate for the workpiece material before commencing the cut. Note that this item is designated non-returnable and non-cancelable by the manufacturer.
