M.a. Ford. 20408900 Jobber Length Drill Bit No. 43

Product Description

The M.A. FORD. 20408900 is a solid carbide jobber length drill bit in wire gauge size No. 43, with a decimal diameter of 0.0890 inches. It features a 118-degree faceted point angle and a web-thinned, tapered web configuration that reduces entry resistance and improves chip evacuation. The bright, uncoated finish suits general-purpose drilling across a range of workpiece materials. With an overall length of 2 inches and a flute length of 1 inch, this bit fits standard jobber-length drilling operations in production and maintenance environments. It is installed and used by machinists, tool and die professionals, and maintenance technicians.

This drill bit is rated for use in cast iron, non-ferrous metals, stainless steel, and steel workpieces. The regular spiral flute with a 5xD flute-to-diameter ratio supports efficient chip clearing in through-hole and blind-hole applications. The straight-cylindrical shank with a diameter of 0.0890 inches seats directly in standard drill chucks and collet holders. Series 204 positions this bit as a general-purpose option for small-diameter precision drilling in both shop and field environments.

Key Features

• 118-degree faceted point with web thinning for reduced thrust and cleaner entry
• Regular spiral flute, 5xD ratio, for consistent chip evacuation in ferrous and non-ferrous materials
• Bright, uncoated finish suitable for general-purpose applications across multiple workpiece materials
• Straight-cylindrical shank at 0.0890 inches diameter for direct chuck or collet mounting
• Manufactured to ISO 9001:2015 certified quality standards

Compatibility

Designed as an OEM-style general-purpose drill bit compatible with standard drill chucks and collet systems accepting a 0.0890-inch straight-cylindrical shank. Rated for cast iron, non-ferrous metal, stainless steel, and steel workpieces per manufacturer specification.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard drill press, CNC, or hand-held power tool setups. Secure the shank fully within the chuck or collet before operation to prevent runout. Ensure the workpiece is properly fixtured and that cutting speed and feed rate are appropriate for the workpiece material and bit diameter. Coolant through is not supported on this bit; apply external coolant or cutting fluid as required by the application.
