M.a. Ford. 30008100 Circuit Board Drill Bit Size 46

Product Description

The M.A. FORD. 30008100 is a solid carbide circuit board drill bit designed for precision drilling in PCB fabrication, light manufacturing, and general-purpose applications requiring tight tolerances. It carries a wire gauge size of 46, which corresponds to a decimal diameter of 0.0810 inches (2.06 mm). The 118-degree drill point angle suits a wide range of materials, while the fast spiral flute geometry promotes efficient chip evacuation during high-speed drilling operations. With a helix angle of 35 degrees and a tapered web configuration, this bit is built for accuracy and rigidity in demanding production environments. Installation is typically performed by machinists, printed circuit board technicians, and tool-and-die professionals.

This drill bit is suited for use in CNC drill presses, benchtop drill stations, and automated PCB drilling equipment where a 2.06 mm shank diameter is required. It is rated for use in cast iron, non-ferrous metals including aluminum and brass, steel, and plastics. The heavy-duty grade construction makes it appropriate for both production-volume runs and precision prototype work where dimensional accuracy is critical. Its compact overall length of 1.5 inches keeps deflection minimal in shallow-depth drilling setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Wire size 46 with 0.0810-inch decimal diameter and tight tolerance of -0.0005 to +0.0000 inches
• 118-degree drill point angle with tapered web for accurate self-centering on entry
• Fast spiral flute with 35-degree helix angle for effective chip removal at high RPM
• Right-hand cutting direction compatible with standard drill press and CNC spindle rotation
• Uncoated finish suitable for use with or without cutting fluid depending on workpiece material

Compatibility

Designed as an OEM-style replacement or direct-fit drill bit for equipment accepting a 2.06 mm round shank, including standard CNC PCB drilling machines and benchtop drill presses configured for small-diameter carbide tooling. Compatible workpiece materials include cast iron, non-ferrous metals, steel, and plastics per Series 300 material application ratings.

Installation Notes

This bit should be installed by qualified machinists or technicians familiar with small-diameter carbide tooling. Carbide is brittle — avoid side loading, impact, or overtightening in the chuck, as these actions can cause chipping or fracture. Confirm spindle runout is within acceptable limits before use, as excessive runout accelerates wear and reduces hole accuracy. Always power down and lock out the drill press or CNC spindle before changing tooling.
