M.a. Ford. 20403300 Carbide Jobber Drill Bit Size 66

Product Description

The M.A. FORD. 20403300 is a solid carbide jobber length drill bit in wire gauge size 66, with a decimal diameter of 0.0330 inches and a 118-degree faceted point angle. It is designed for high-precision drilling in demanding materials including cast iron, stainless steel, steel, and non-ferrous metals. The two-flute regular spiral design promotes efficient chip evacuation, and the web-thinned, tapered web construction reduces thrust and improves point stability at entry. Overall length is 1.5 inches with a 0.375-inch flute length. The bright uncoated finish suits general-purpose applications where coating is not required. This bit is typically installed by machinists, tool-and-die technicians, and maintenance professionals working with precision tooling setups.

The 20403300 is suited for general-purpose drilling operations in both production and maintenance environments. Its 5xD flute-to-diameter ratio supports drilling in cast iron, stainless steel, carbon steel, and non-ferrous metals. The straight-cylindrical shank fits standard drill chucks and collet holders used in CNC machining centers, drill presses, and handheld power tools. Series 204 identifies this as part of M.A. FORD.'s standard jobber-length solid carbide drill line, built to ISO 9001:2015 quality standards.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Wire size 66 (0.0330 inches decimal) with diameter tolerance of -0.0005 to 0.0000 inches
• 118-degree faceted point angle with web-thinned, tapered web for reduced entry thrust
• Two-flute regular spiral design promotes consistent chip flow
• Straight-cylindrical shank at 0.0330 inches diameter for compatibility with standard chucks and collets
• ISO 9001:2015 certified manufacturing process

Compatibility

Designed as a general-purpose OEM-style solid carbide jobber drill for use in standard drill chucks and collet systems accepting a 0.0330-inch straight-cylindrical shank. Suitable for use in cast iron, non-ferrous metal, stainless steel, and steel workpieces as noted by primary workpiece material codes K, M, N, and P.

Installation Notes

This drill bit is installed by machinists and metalworking technicians in drill press, milling, or CNC spindle setups. Power down and de-energize all equipment before changing tooling. Ensure the chuck or collet is properly sized for the 0.0330-inch shank diameter and that runout is minimized before drilling operations begin. Coolant-through is not supported on this bit; use external coolant or cutting fluid as appropriate for the workpiece material.
