M.a. Ford 20419100 Carbide Jobber Drill Bit No.11

Product Description

The M.A. FORD 20419100 is a solid carbide jobber-length drill bit sized at No. 11 wire gauge (0.1910 inch decimal) with a 118-degree faceted drill point. The bit features a two-flute regular spiral design with web thinning for improved chip evacuation and reduced thrust during entry. At 2-3/4 inches overall length with a 1-5/8-inch flute length, it fits standard jobber-length drill chucks and is suited for general-purpose drilling in production and maintenance environments. The bright, uncoated finish keeps heat transfer predictable and works well with cutting fluids. Machinists and fabricators install this bit in CNC machining centers, knee mills, and hand-held drill motors.

This drill bit is intended for drilling cast iron, non-ferrous metals, stainless steel, and carbon steel. The solid carbide construction provides the rigidity needed for harder workpiece materials where high-speed steel bits deflect or wear prematurely. The straight-cylindrical shank accepts standard drill chucks without adapters, making it a practical choice for both bench-mounted drill presses and portable applications in fabrication shops and field maintenance settings.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• No. 11 wire gauge size, 0.1910 inch decimal diameter with a tight tolerance of -0.0005 to 0.0000 inch
• 118-degree faceted point angle with web thinning for reduced entry thrust
• Two-flute regular spiral design promotes chip clearance in through-hole drilling
• Bright, uncoated finish compatible with a wide range of cutting fluids
• ISO 9001:2015 certified manufacturing for consistent dimensional accuracy

Compatibility

Designed for general-purpose drilling in cast iron, non-ferrous metals, stainless steel, and steel workpieces. Compatible with any standard drill chuck accepting a 0.1910-inch straight-cylindrical shank.

Installation Notes

Secure the shank fully in the drill chuck and verify runout before beginning a cut. Machinists should use appropriate cutting fluid or coolant for the workpiece material, especially when drilling stainless steel or cast iron. Ensure spindle speed is set per manufacturer feed-and-speed recommendations for solid carbide tooling at this diameter. Inspect the cutting edges for chipping before each use, as solid carbide is brittle and sensitive to impact or side loading.
