M.a. Ford 20403800 Carbide Jobber Drill Bit No. 62

Product Description

The M.A. FORD 20403800 is a solid carbide jobber length drill bit in wire gauge size No. 62, with a decimal diameter of 0.0380 inches. It features a 118-degree faceted drill point, a two-flute regular spiral design, and a web-thinned, tapered web configuration for reduced thrust during entry. The bright, uncoated finish is suited for general-purpose drilling in a range of metalworking applications. Overall length is 1.5 inches with a 0.5-inch flute length. A straight-cylindrical shank matches the bit diameter at 0.0380 inches, allowing use in standard drill chucks and collet holders. The bit is manufactured to ISO 9001:2015 standards and carries a diameter tolerance of -0.0005 to 0.0000 inches.

This drill bit is designed for small-diameter general-purpose drilling in production and maintenance environments. Primary workpiece materials include cast iron, non-ferrous metals, stainless steel, and carbon or alloy steel, covering material codes K, M, N, and P. The 5xD flute-to-diameter ratio and right-hand cutting direction make it appropriate for CNC machining centers, drill presses, and hand-held drill motor applications where tight hole tolerances in small diameters are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• No. 62 wire gauge size, 0.0380-inch decimal diameter with tight tolerance of -0.0005 to 0.0000 inches
• 118-degree faceted point for accurate entry without walking
• Web-thinned tapered web reduces axial cutting force
• Right-hand, regular spiral flute with 5xD ratio for efficient chip evacuation
• ISO 9001:2015 certified manufacturing

Compatibility

Designed as a general-purpose replacement or stock drill bit for applications requiring No. 62 wire gauge, 0.0380-inch diameter holes in cast iron, non-ferrous metal, stainless steel, and steel workpieces.

Installation Notes

Installation of this bit should be performed by a qualified machinist or tooling technician. Secure the straight-cylindrical shank firmly in a compatible drill chuck or collet before operation, and verify runout before engaging the workpiece. Power down or de-energize the machine and allow all moving parts to stop completely before changing bits. No coolant-through capability is present on this bit; use external cutting fluid appropriate for the workpiece material when drilling stainless steel or cast iron.
