M.a. Ford. 30012500 Circuit Board Drill Bit 1/8 in

Product Description

The M.A. FORD. 30012500 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 Series 300 specifications, it features a 118-degree drill point angle and a right-hand cutting direction with a 35-degree helix angle. The two-flute, tapered web design clears chips efficiently and reduces heat buildup at the cutting edge. At 0.125 inches in diameter with a matching 0.125-inch shank, this is a tight-tolerance tool ground to a diameter tolerance of -0.0005 to +0.0000 inches. It is suited for machinists, PCB technicians, and production shop operators who need consistent, repeatable hole geometry in small-diameter work.

This drill bit is rated for use in cast iron, non-ferrous metals, steel, and plastics, making it versatile across light machining and circuit board drilling operations. The fast spiral geometry promotes aggressive chip evacuation, which is critical when drilling through laminated PCB materials or stacked non-ferrous sheet stock. With a 5/8-inch flute length and a 1.5-inch overall length, it fits standard drill press chucks, CNC spindles, and handheld precision drill drivers configured for 1/8-inch shanks. The uncoated solid carbide construction delivers consistent cutting performance without coating delamination concerns in abrasive materials.

Key Features

• Solid carbide construction rated heavy-duty for extended tool life in abrasive workpiece materials
• 118-degree drill point angle for accurate self-centering entry on flat and curved surfaces
• Fast spiral with 35-degree helix angle for efficient chip evacuation in deep or stacked-material drilling
• Tapered web configuration reduces thrust force requirements at the cutting tip
• Tight diameter tolerance of -0.0005 to +0.0000 inches ensures consistent hole sizing
• Right-hand cutting direction compatible with standard drill press and CNC spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for applications requiring a 1/8-inch, 118-degree point, fast spiral carbide drill in circuit board, cast iron, non-ferrous metal, steel, or plastic drilling operations.

Installation Notes

Installation and use should be performed by machinists or qualified shop technicians familiar with carbide tooling. Secure the shank fully in the chuck or collet before operation and verify spindle runout is within acceptable limits, as carbide bits are brittle and sensitive to lateral loading. Power down the drill press or CNC machine completely before changing tooling. Avoid using carbide bits in hand drills where torque control is limited, as side loading can cause bit fracture.
