M.a. Ford 20416600 Jobber Drill Bit No. 19 Solid Carbide

Product Description

The M.A. FORD 20416600 is a jobber-length drill bit sized to wire gauge No. 19, with a decimal diameter of 0.1660 inches. Manufactured from solid carbide with a bright uncoated finish, it features a 118-degree faceted point, a regular spiral flute, and a straight-cylindrical shank. Overall length is 2-3/4 inches with a flute length of 1-5/8 inches. The two-flute, web-thinned design reduces entry force and improves chip evacuation. Diameter tolerance is held to -0.0005 to 0.0000 inches, making it appropriate for precision hole applications in demanding materials. This is a Series 204 general-purpose bit produced to ISO 9001:2015 standards.

This drill bit is suited for drilling cast iron, non-ferrous metals, stainless steel, and steel in both production and maintenance environments. The 5xD flute-to-diameter ratio provides adequate chip clearance for through-hole drilling in moderate-depth applications. It is commonly used by machinists, tool-and-die tradespeople, and maintenance technicians working with hand-held or bench-mounted drilling equipment. The right-hand cutting direction and straight shank allow direct use in standard drill chucks without adapters.

Key Features

• Solid carbide construction for hardness and heat resistance in ferrous and non-ferrous materials
• 118-degree faceted point with web-thinned geometry for reduced thrust and cleaner entry
• Bright uncoated finish suitable for general-purpose drilling without coolant-through requirement
• Diameter tolerance of -0.0005 to 0.0000 inches for consistent, repeatable hole sizing
• Regular spiral, two-flute design promotes chip evacuation in short-to-moderate depth holes
• ISO 9001:2015 certified manufacturing process

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks accepting a 0.1660-inch straight-cylindrical shank. Suitable for drilling cast iron, non-ferrous metals, stainless steel, and steel workpieces.

Installation Notes

Secure the straight shank fully in a properly sized drill chuck before operation. Power down or de-energize all drilling equipment before bit changes or chuck adjustments. Solid carbide bits are brittle and should not be used in setups with excessive runout or lateral loading, as this can cause chipping or fracture. Ensure workpiece is properly fixtured to prevent movement during the cut.
