M.a. Ford. 20408100 Carbide Jobber Drill Bit No. 46

Product Description

The M.A. FORD. 20408100 is a solid carbide jobber-length drill bit in wire gauge size No. 46, equivalent to 0.0810 inches in diameter. It features a 118-degree faceted drill point and a two-flute regular spiral design with web thinning for improved chip evacuation and reduced thrust. The overall length is 1.75 inches with a flute length of 0.875 inches, and the straight-cylindrical shank matches the 0.0810-inch drill diameter. This bit is manufactured under ISO 9001:2015 certified processes and is suited for production drilling and precision hole work performed by machinists and tool and die professionals.

The 20408100 is a general-purpose drill bit designed for drilling cast iron, non-ferrous metals, stainless steel, and steel. Its solid carbide construction and bright uncoated finish make it well suited for short-run and production applications where dimensional accuracy and hole quality are priorities. The 5xD flute-to-diameter ratio supports stable chip flow in small-diameter drilling operations. It does not include coolant-through capability, so external coolant or cutting fluid is recommended when drilling harder workpiece materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in metalworking applications
• 118-degree faceted point with web thinning for reduced entry thrust and improved centering
• Two-flute regular spiral design with tapered web configuration for consistent chip removal
• Bright uncoated finish compatible with a wide range of cutting fluids and workpiece materials
• Straight-cylindrical shank fits standard drill chucks and collet systems accepting 0.0810-inch shanks
• Manufactured to ISO 9001:2015 certified standards for dimensional consistency

Compatibility

Designed as an OEM-style general-purpose jobber drill bit for use in standard drill chucks, collet holders, and CNC machining centers accepting straight-cylindrical shanks at 0.0810 inches diameter.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or tooling professional. Secure the shank fully in a properly rated chuck or collet before operation and verify runout before drilling. External cutting fluid or coolant is recommended when working with stainless steel or cast iron to manage heat and extend tool life. Do not exceed the manufacturer-recommended feed and speed parameters for the workpiece material being drilled.
