M.a. Ford 30201180 Micro Drill Bit 0.0118 in Solid Carbide

Product Description

The M.A. FORD 30201180 is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It features a 0.0118-inch (0.30 mm) diameter, a 130-degree point angle, and a fast spiral flute geometry that promotes efficient chip evacuation in small-bore work. The straight-cylindrical shank measures 3.17 mm and is compatible with standard collet chucks. With an overall length of 38 mm and a flute length of 4.80 mm, this bit is built for controlled, accurate penetration. It carries a bright/uncoated finish and is manufactured to ISO 9001:2015 standards. Machinists and toolroom technicians working with precision CNC equipment or manual micro-drilling setups are the primary users.

This micro drill bit is suited for drilling cast iron, hardened steel, stainless steel, alloy steel, carbon steel, aluminum, non-ferrous metals, tool steel, and special alloys. It is appropriate for both production and prototype environments where hole diameter consistency and bit integrity at sub-0.020-inch sizes are critical. The Series 302 designation places it within M.A. FORD's established micro-drill line, making it a go-to choice for precision component manufacturing, mold and die work, and electronics fabrication where small, accurate through-holes are required.

Key Features

• 0.0118-inch (0.30 mm) diameter with a diameter tolerance of +0.000 to -0.013 mm for tight-fit hole accuracy
• 130-degree point angle reduces thrust force and improves centering on entry
• Fast spiral flute design promotes chip clearance in deep micro-bore cuts
• Solid carbide construction provides rigidity and wear resistance in hard and abrasive workpiece materials
• Bright/uncoated finish suitable for a wide range of workpiece materials including non-ferrous metals and aluminum
• Right-hand cutting direction with 2 flutes; straight-cylindrical shank fits standard collet tooling

Compatibility

Designed for use with standard collet-style tool holders accepting a 3.17 mm straight-cylindrical shank. Compatible workpiece materials include cast iron, hardened steel, stainless steel, alloy steel, carbon steel, aluminum, non-ferrous metals, tool steel, and special alloys per manufacturer specification.

Installation Notes

Micro drill bits at this diameter require a CNC machining center, precision drill press, or dedicated micro-drilling spindle capable of high RPM and minimal runout. Secure the shank firmly in a collet chuck to minimize deflection. At sub-0.015-inch diameters, bit breakage risk increases sharply with misalignment, excessive feed rate, or inadequate chip clearing. Always verify spindle runout and collet condition before use, and follow the machine manufacturer's feed and speed recommendations for the specific workpiece material.
