M.a. Ford. 30201000 Circuit Board Drill Bit Size 87 Carbide

Product Description

The M.A. FORD. 30201000 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and small-hole machining applications. Manufactured from solid carbide for rigidity and wear resistance, this bit carries a wire gauge size of 87, equal to 0.0100 inches (0.25 mm) in decimal diameter. The 130-degree split point geometry promotes accurate entry and reduces walking on hard substrates. Overall length is 1.5 inches, with a flute length of 0.150 inches and a fast spiral with a 35-degree helix angle to clear chips efficiently from small-diameter bores. The shank diameter is 0.125 inches (1/8 inch), compatible with standard precision drill chucks and CNC drill spindles.

This drill bit is suited for close-tolerance drilling in cast iron, non-ferrous metals, alloy steel, carbon steel, stainless steel, high-temperature alloys, and titanium. The bright uncoated finish maintains dimensional accuracy at the cutting edge, making it appropriate for applications where coating buildup at sub-0.020-inch diameters would compromise hole tolerance. It is typically used in CNC drilling centers, PCB drill presses, and precision machining operations that require consistent hole geometry in dense or abrasive workpiece materials. The tapered web configuration supports strength at the tip without adding unnecessary material that could deflect in micro-diameter applications.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard and abrasive materials
• Wire gauge size 87 - 0.0100 inches (0.25 mm) cutting diameter
• 130-degree drill point angle for accurate entry and reduced thrust force
• Fast spiral with 35-degree helix angle promotes efficient chip evacuation in small bores
• Bright uncoated finish maintains precise diameter tolerance of -0.0003 to 0.0000 inches
• Tapered web configuration balances tip strength and deflection resistance
• Right-hand cut, two-flute geometry - Series 302

Compatibility

Designed as a direct-fit circuit board drill bit for CNC and manual precision drilling equipment accepting a 1/8-inch (0.125-inch) shank. Rated for use in cast iron, non-ferrous metal, alloy steel, carbon steel, stainless steel, high-temperature alloy, and titanium workpieces per manufacturer material application data.

Installation Notes

Installation and use should be performed by machinists or CNC technicians familiar with micro-diameter tooling. Secure the shank fully in a precision collet or drill chuck rated for the spindle speed required for this diameter. At sub-0.020-inch diameters, excessive feed rate or runout in the spindle will cause tool breakage - verify spindle runout before use. Follow all machine guarding and PPE requirements per applicable shop safety standards.
