M.a. Ford. 20416100 Carbide Jobber Drill Bit No. 20

Product Description

The M.A. FORD. 20416100 is a solid carbide jobber length drill bit in wire gauge size No. 20, with a decimal diameter of 0.1610 inches. It features a 118-degree faceted point, a two-flute regular spiral geometry, and a bright uncoated finish. The overall length is 2.5 inches with a flute length of 1.375 inches and a straight cylindrical shank diameter of 0.1610 inches. Web thinning is applied to reduce thrust and improve chip evacuation. This bit is designed for general-purpose drilling and is installed by machinists, tool-and-die technicians, and maintenance professionals in shop and field environments.

The 20416100 is suited for drilling cast iron, non-ferrous metals, stainless steel, and steel. Its solid carbide construction maintains cutting edge integrity at higher speeds and feeds compared to high-speed steel alternatives. The 5xD flute-to-diameter ratio supports adequate chip clearance in moderate-depth hole applications. This bit fits standard drill chucks and CNC tool holders accepting a 0.1610-inch straight shank, making it appropriate for both manual drilling and light production work.

Key Features

• Solid carbide construction for extended tool life in ferrous and non-ferrous materials
• 118-degree faceted point with web thinning to reduce entry thrust
• Two-flute regular spiral design for efficient chip evacuation
• Bright uncoated finish compatible with a wide range of cutting fluids
• Diameter tolerance of -0.0005 to 0.0000 inches for consistent hole sizing
• Manufactured under ISO 9001:2015 certified quality standards

Compatibility

Designed as a general-purpose jobber length drill bit for use in standard drill chucks and CNC tool holders that accept a 0.1610-inch straight cylindrical shank, compatible with cast iron, non-ferrous metal, stainless steel, and steel workpiece materials.

Installation Notes

Install in a properly sized drill chuck or collet, ensuring the shank is fully seated and secured before operation. Power down or de-energize the machine spindle before changing tooling. Confirm spindle speed and feed rate are appropriate for the workpiece material and bit diameter prior to drilling. Carbide tooling is brittle and should not be used in applications with significant lateral loading or interrupted cuts that exceed the tool design limits.
