M.a. Ford 20005500 Die Drill Bit 0.055 in Carbide

Product Description

The M.A. FORD 20005500 is a straight-flute die drill bit engineered for precision holemaking in demanding materials. Built from solid carbide and left uncoated, it measures 0.0550 inches in diameter — equivalent to wire size #54 — with a 135-degree split point that reduces thrust and self-centers on entry. Overall length is 1.5 inches with a 0.3125-inch flute length. The web-thinned geometry improves chip evacuation and cutting efficiency in tough workpiece materials. This bit is suited for machinists, tool-and-die technicians, and precision manufacturing shops working with small-diameter, tight-tolerance holes.

The 20005500 is designed for holemaking applications in cast iron, stainless steel, alloy steel, non-ferrous metals, titanium, high-temperature alloys, hardened materials, glass, and ceramics. Its right-hand cutting direction and straight-flute design make it a go-to choice for die work, mold making, and precision part manufacturing where dimensional accuracy and clean entry are critical. The Series 200 designation identifies it within M.A. FORD's standard solid carbide drill lineup.

Key Features

• Solid carbide construction for rigidity and wear resistance in abrasive and hard materials
• 135-degree split point reduces entry thrust and improves self-centering
• Web-thinned geometry promotes chip evacuation in deep or difficult cuts
• Uncoated finish — suitable for use with cutting fluids across a wide material range
• Diameter tolerance of +0.0000 to -0.0005 inches ensures close-fit hole sizing
• Right-hand cut, 2-flute configuration compatible with standard drill press and CNC setups

Compatibility

Designed as an OEM-style precision drill for use in standard drill chucks, collets, and CNC spindles accepting a 0.0550-inch shank diameter. Rated for primary workpiece materials including cast iron, non-ferrous metal, stainless steel, and steel, with secondary capability in alloy steel, austenitic stainless steel, titanium, high-temperature alloys, hardened materials, glass, and ceramics. Conforms to DIN standards.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with small-diameter carbide drill handling. Carbide is brittle — avoid side-loading, interrupted cuts without proper setup, or excessive runout in the spindle, as these conditions can cause breakage. Ensure the chuck or collet is clean and properly seated before running. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality.
