M.a. Ford. 30203540 Micro Drill Bit 0.0354 in Carbide

Product Description

The M.A. FORD. 30203540 is a solid carbide micro drill bit designed for precision drilling in demanding materials. It features a 130-degree point angle and a fast spiral flute geometry that promotes chip evacuation and reduces heat buildup during cutting. The straight-cylindrical shank measures 3.18 mm (approximately 0.125 inches) in diameter, and the overall length is 38 mm (approximately 1.496 inches). With a cutting diameter of 0.0354 inches (0.90 mm) and a diameter tolerance of +0.000 to -0.013 mm, this bit is suited for close-tolerance work where dimensional accuracy matters. It is installed by machinists, tool-and-die professionals, and precision fabricators working with CNC or manual drilling equipment.

This micro drill bit is appropriate for use in both production and job-shop environments where small-diameter holes are required in hard or abrasive workpiece materials. Primary workpiece materials include cast iron, hardened steel, non-ferrous metals, stainless steel, and steel. Secondary materials include alloy steel, aluminum, carbon steel, non-ferrous metals, special alloys, and tool steel. The bright uncoated finish makes the bit suitable for applications where coating interaction with the workpiece is a concern or where re-grinding is anticipated.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 130-degree point angle reduces thrust and improves centering on entry
• Fast spiral flute type promotes efficient chip evacuation in deep or interrupted cuts
• Tight diameter tolerance of +0.000 to -0.013 mm supports close-tolerance hole requirements
• Bright uncoated finish compatible with a wide range of workpiece materials and regrind programs
• Right-hand cutting direction, two flutes, Series 302 designation

Compatibility

Designed as an OEM-style precision micro drill bit in the M.A. FORD. Series 302 line, compatible with standard straight-shank drill chucks and collets accepting a 3.18 mm shank diameter. Suitable for use in CNC machining centers, drill presses, and precision hand-held spindle tools configured for micro-diameter tooling.

Installation Notes

Installation and use of this micro drill bit should be performed by qualified machinists or tooling professionals familiar with small-diameter carbide tooling. Ensure the spindle and chuck or collet are clean and properly seated before securing the shank, as carbide micro bits are brittle and sensitive to runout. Power down and lock out the machine before changing tooling. Avoid side-loading or using feed rates beyond what the material and machine rigidity support, as micro-diameter carbide tools are susceptible to breakage under lateral stress.
