M.a. Ford. 30009800 Circuit Board Drill Bit No.40

Product Description

The M.A. FORD. 30009800 is a solid carbide fast spiral circuit board drill bit designed for precision drilling in printed circuit board fabrication and light industrial applications. Built to wire gauge size No. 40, it measures 0.098 inches (2.49 mm) in diameter with a 118-degree drill point angle for clean entry and reduced walking on hard substrates. The fast spiral geometry and tapered web configuration promote efficient chip evacuation, which is critical when drilling through thin, layered board materials. This bit is suited for CNC drilling operations and is installed by electronics manufacturing technicians and precision machining professionals.

This drill bit is designed for use on cast iron, non-ferrous metals, plastics, and steel, making it a versatile option in both circuit board drilling operations and light general machining setups. The uncoated solid carbide construction holds up well under high-RPM conditions common to CNC drilling machines. The 35-degree helix angle supports aggressive chip removal, reducing heat buildup and bit deflection during through-hole drilling. It is sold individually and is appropriate wherever repeatable, tight-tolerance hole placement is required in production or repair environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-RPM drilling
• No. 40 wire size, 0.098 inches (2.49 mm) diameter for precise through-hole sizing
• 118-degree drill point angle reduces walking and improves entry accuracy
• Fast spiral with 35-degree helix angle promotes efficient chip evacuation
• Tapered web configuration adds cutting edge strength and reduces thrust requirements
• Right-hand cutting direction, compatible with standard CNC and benchtop drill spindles

Compatibility

Designed as an OEM-style replacement or production-use drill bit for CNC and manual drilling equipment accepting a 0.098 inch (2.49 mm) straight shank, suitable for circuit board and light industrial drilling applications in cast iron, non-ferrous metals, plastics, and steel.

Installation Notes

Installation and use of this bit should be performed by qualified machining or electronics manufacturing technicians familiar with CNC drill press operation and bit change procedures. Ensure the spindle is fully powered down and the collet or chuck is fully released before inserting or removing the bit. Verify proper shank seating depth and collet torque per the equipment manufacturer specifications before initiating a drilling cycle. Do not exceed the rated RPM range for the bit diameter, as carbide tooling is susceptible to fracture under excessive lateral load or vibration.
