M.a. Ford 30204000 Micro Drill Bit Size 60 Solid Carbide

Product Description

The M.A. FORD 30204000 is a solid carbide micro drill bit designed for precision small-diameter drilling in demanding material applications. It carries a wire gauge size of 60, which corresponds to a decimal diameter of 0.0400 inches, with a 130-degree point angle suited for entry stability in hard and abrasive materials. Overall length is 1.5 inches, with a flute length of 0.4000 inches and a straight-cylindrical shank diameter of 1/8 inch. The bright, uncoated finish and fast spiral flute geometry are standard for this Series 302 design. This bit is installed by machinists, toolroom technicians, and precision fabricators working with CNC mills, drill presses, and precision spindle equipment.

This micro drill bit is used in applications requiring tight-tolerance, small-diameter holes in a wide range of workpiece materials. Primary material compatibility includes cast iron, hardened steel, non-ferrous metals, stainless steel, and steel. Secondary material applications include alloy steel, aluminum, carbon steel, cast iron, non-ferrous metals, special alloys, stainless steel, and tool steel. It is well suited for production and toolroom environments where repeatable accuracy at small diameters is required. The right-hand cutting direction and two-flute spiral configuration support chip evacuation in both ferrous and non-ferrous materials.

Key Features

• Solid carbide construction provides rigidity and wear resistance at the 0.0400-inch diameter
• 130-degree point angle supports accurate entry and reduced walking on hard materials
• Fast spiral flute type aids chip evacuation during drilling
• Straight-cylindrical shank at 1/8 inch fits standard collets and chucks
• Bright, uncoated finish suitable for use with or without cutting fluid
• Diameter tolerance held to +0.0000 to -0.0005 inches for consistent fit

Compatibility

Designed for use in applications involving cast iron, hardened steel, non-ferrous metals, stainless steel, steel, alloy steel, aluminum, carbon steel, special alloys, and tool steel workpieces. Shank diameter of 1/8 inch fits collets and drill chucks accepting that size. Verify spindle speed and feed rate suitability for the workpiece material before use.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with small-diameter carbide tooling. Secure the shank firmly in a collet or chuck rated for 1/8-inch diameter before operation. Carbide micro drills are brittle at this diameter - avoid lateral loading, interrupted cuts without appropriate feed reduction, and excessive runout, which can cause immediate breakage. Always confirm spindle speed, feed rate, and workpiece fixturing before engaging the cut.
