M.a. Ford. 20412850 Solid Carbide Jobber Drill Bit No. 30

Product Description

The M.A. FORD. 20412850 is a solid carbide jobber length drill bit sized at No. 30 (0.1285 inches decimal) with a 118-degree faceted point angle. It is designed for general-purpose drilling in ferrous and non-ferrous materials and belongs to the Series 204 product line. The bit features a regular spiral flute, a web-thinned tip for easier entry, and a bright uncoated finish. With an overall length of 2.25 inches and a 1.25-inch flute length, it fits standard drill chucks via its straight-cylindrical shank. Machinists, tool-and-die technicians, and maintenance trades use this bit for production and repair drilling applications.

This bit is suited for drilling cast iron, non-ferrous metals, stainless steel, and steel in both shop and field environments. The solid carbide construction supports higher cutting speeds than high-speed steel and holds edge geometry longer in abrasive or hard materials. The 5xD flute-to-diameter ratio provides adequate chip evacuation in standard depth holes. It is a single-piece, right-hand-cut tool sold individually.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• 118-degree faceted point with web thinning for reduced entry force and improved centering

• Manufactured under ISO 9001:2015 certified quality standards

Compatibility

Designed as a general-purpose OEM-style jobber drill bit for use in standard drill chucks, collet systems, and CNC toolholders accepting a 0.1285-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drilling operations. Ensure the drill press, lathe, or CNC spindle is fully stopped and de-energized before changing or seating the bit. Solid carbide tooling is brittle and can fracture under side-load or interrupted cuts - avoid flex in the workpiece setup. Verify shank seating depth and runout before beginning a production run.
