M.a. Ford 30202800C Size 70 Micro Drill Bit Solid Carbide

Product Description

The M.A. FORD 30202800C is a solid carbide micro drill bit designed for precision drilling in demanding metalworking applications. Built to Series 302 specifications, this wire gauge size 70 bit measures 0.0280 inches in diameter with a 130-degree drill point angle and a fast spiral flute geometry. The ALtima coating improves surface hardness and wear resistance, extending tool life in abrasive materials. Overall length is 1.5 inches with a flute length of 0.25 inches. The straight-cylindrical shank measures 1/8 inch in diameter, providing consistent chuck retention. Right-hand cutting direction makes this bit compatible with standard drill presses, CNC machining centers, and precision hand tools used by machinists and tool-and-die professionals.

This micro drill bit is suited for high-precision drilling in cast iron, hardened steel, stainless steel, alloy steel, carbon steel, aluminum, non-ferrous metals, tool steel, and special alloys. Its small diameter and carbide construction make it a practical choice for printed circuit board work, instrument manufacturing, mold and die applications, and other close-tolerance machining tasks where standard high-speed steel bits lack the rigidity and wear resistance needed to hold dimensional accuracy at depth.

Key Features

• Solid carbide construction resists deflection and wear in hard and abrasive workpiece materials
• ALtima coating provides enhanced surface hardness and extended tool life
• 130-degree drill point angle reduces thrust force and improves centering on hard materials
• Fast spiral flute geometry promotes efficient chip evacuation in deep micro holes
• Straight-cylindrical 1/8 inch shank fits standard collets and drill chucks
• Right-hand cut, size 70 wire gauge at 0.0280 inches diameter for close-tolerance work
• Manufactured to ISO 9001:2015 quality standards

Compatibility

Designed for use in CNC machining centers, drill presses, and precision hand tools accepting a 1/8 inch straight-cylindrical shank. Suitable for drilling cast iron, hardened steel, stainless steel, alloy steel, carbon steel, aluminum, non-ferrous metals, tool steel, and special alloys per manufacturer workpiece material ratings.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or tooling technicians familiar with micro-diameter carbide tooling. Secure the shank fully in the collet or chuck before operation and verify runout is within acceptable limits, as carbide micro drills are brittle and susceptible to breakage from lateral load or misalignment. Always power down and lock out the spindle before changing tooling. Cutting speeds and feeds should be matched to workpiece material and machine rigidity per the manufacturer or applicable machining reference data.
