M.a. Ford 30020100 Circuit Board Drill Bit Size 7 0.2010 in

Product Description

The M.A. FORD 30020100 is a solid carbide circuit board drill bit designed for precision hole drilling in circuit boards, cast iron, non-ferrous metals, and plastics. It carries a wire gauge size of 7, equal to 0.2010 inches (5.11 mm) in diameter, and features a 118-degree drill point angle with a fast spiral configuration for efficient chip evacuation. The tapered web and 35-degree helix angle promote clean entry and reduce heat buildup in demanding materials. With a heavy-duty grade designation and right-hand cutting direction, this bit suits production and field drilling environments alike. It is installed by machinists, electronics technicians, and trade professionals working with tight-tolerance applications.

This drill bit is rated for use in cast iron, non-ferrous metals, and plastics, making it a versatile choice for circuit board fabrication and general precision drilling tasks. The 0.75-inch flute length and 1.5-inch overall length suit compact drilling setups where clearance is limited. The fast spiral geometry helps clear chips quickly, reducing the risk of bit binding or workpiece damage. It is sold individually and is appropriate for both bench drill press and CNC spindle applications where a size 7 wire gauge hole is required.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 118-degree drill point angle for standard entry geometry on metal and plastic substrates
• Fast spiral with 35-degree helix angle promotes aggressive chip evacuation
• Tapered web configuration adds core strength and reduces walking on entry
• Right-hand cut, uncoated finish — compatible with standard drill press and CNC spindle toolholders
• Heavy-duty grade rating for extended tool life in production drilling

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide drill bit for applications requiring a wire gauge size 7 (0.2010 inch) bore in circuit boards, cast iron, non-ferrous metals, and plastics. Series 300 designation per M.A. FORD product line.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trained technicians familiar with carbide tooling. Solid carbide bits are brittle and should not be used in setups with excessive runout or lateral load. Secure the shank firmly in a compatible collet or chuck rated for the 0.2010-inch shank diameter before operation. Always wear appropriate eye protection and follow applicable shop safety standards when operating drilling equipment.
