M.a. Ford. 30202102 Micro Drill Bit Size 75 0.0210 in

Product Description

The M.A. FORD. 30202102 is a solid carbide micro drill bit designed for precision drilling in demanding materials. Built to Series 302 specifications, it carries a wire gauge size of 75 with a decimal diameter of 0.0210 inches and a 130-degree drill point angle optimized for hard and abrasive workpiece materials. The bright/uncoated finish keeps tolerances tight, with a diameter tolerance held to +0.0000 to -0.0005 inches. At 1.5 inches overall length with a 1/8-inch straight cylindrical shank, this bit fits standard collet and drill chuck setups used by machinists and toolroom technicians working in precision metalworking environments.

This micro drill bit is suited for drilling cast iron, hardened steel, stainless steel, carbon steel, alloy steel, tool steel, aluminum, non-ferrous metals, and special alloys. The fast spiral flute geometry aids chip evacuation in deep, small-diameter holes. It is appropriate for CNC machining centers, drill presses, and manual machine tool setups where fine hole diameters and dimensional accuracy are required. Secondary workpiece materials include aluminum, carbon steel, and non-ferrous metals, making this a versatile choice across production and repair machining applications.

Key Features

• Solid carbide construction delivers hardness and wear resistance in tough workpiece materials
• 130-degree drill point angle suited for cast iron, stainless steel, and hardened steel
• Fast spiral flute type promotes efficient chip evacuation in small-diameter holes
• Diameter tolerance of +0.0000 to -0.0005 inches ensures precision fitment
• Bright/uncoated finish maintains dimensional accuracy without coating buildup
• 1/8-inch straight cylindrical shank for compatibility with standard collets and chucks

Compatibility

Designed as an OEM-style micro drill bit for use in standard 1/8-inch collet and straight-shank drill chuck setups in CNC and manual machining applications.

Installation Notes

Installation and use of this bit should be performed by qualified machinists familiar with micro-diameter tooling. Ensure the machine spindle and collet or chuck are fully de-energized and stopped before tool changes. Micro drill bits are brittle at this diameter — use appropriate feed rates and spindle speeds per material guidelines to avoid breakage. Secure the shank fully in the chuck to minimize runout and extend tool life.
