M.a. Ford. 30204130 Micro Drill Bit 1.05 Mm Solid Carbide

Product Description

The M.A. FORD. 30204130 is a solid carbide micro drill bit engineered for high-precision drilling in demanding materials. Measuring 1.05 mm in diameter (0.0413 inches), it features a 130-degree point angle and a fast spiral flute design that promotes efficient chip evacuation in tight bores. The bright, uncoated finish suits applications where coating interaction with the workpiece is a concern. With an overall length of 38 mm and a straight-cylindrical shank, this bit seats securely in standard collet chucks and drill chucks used in CNC machining centers and precision bench-top drilling setups. Manufactured to ISO 9001:2015 standards, it is suited for machinists, toolroom technicians, and precision fabricators working at tight tolerances.

This micro drill bit is designed for use in cast iron, hardened steel, stainless steel, standard steel, and non-ferrous metals as primary workpiece materials. Secondary applications include alloy steel, aluminum, carbon steel, tool steel, special alloys, and non-ferrous metals. The 130-degree point angle and fast spiral geometry make it well suited for work in harder materials where a sharper entry point and aggressive chip clearance are needed. Typical install scenarios include precision component manufacturing, mold and die work, electronics fabrication, and aerospace part machining where small-diameter holes require tight dimensional control.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 1.05 mm diameter with a diameter tolerance of +0.000 to -0.013 mm for precise hole sizing
• 130-degree point angle reduces thrust and improves centering on entry
• Fast spiral flute type promotes rapid chip evacuation in deep micro holes
• Bright, uncoated finish compatible with a wide range of workpiece materials
• Straight-cylindrical shank at 3.18 mm for secure seating in standard collets

Compatibility

Designed for use with CNC machining centers and precision drilling equipment accepting a 3.18 mm straight-cylindrical shank. Compatible workpiece materials include cast iron, hardened steel, stainless steel, alloy steel, aluminum, carbon steel, tool steel, special alloys, and non-ferrous metals per M.A. FORD. Series 302 application guidelines.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with micro-diameter tooling. Verify that the spindle, collet, and chuck are clean and free of runout before seating the shank, as even minor runout will cause breakage at this diameter. Power down and de-energize the machine before changing tooling. Do not exceed the machine spindle speed and feed rate recommendations for the specific workpiece material and drill diameter.
