M.a. Ford 20623800 Screw Machine Drill Bit 0.238 in Carbide

Product Description

The M.A. FORD 20623800 is a screw machine length drill bit designed for precise, short-reach drilling in production and tool room environments. Built from solid carbide, this bit delivers superior hardness and heat resistance compared to high-speed steel tooling. It features a 0.238 inch diameter (Letter B designation), a 118-degree faceted drill point, and a right-hand spiral flute with web thinning to reduce thrust and improve chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. Carbide construction makes it well suited for repeated high-cycle use in machine shop, CNC, and manual drill press applications.

This bit is intended for drilling cast iron, non-ferrous metals, and plastics. The screw machine length format provides a shorter overall profile than jobber-length bits, improving rigidity and reducing deflection in close-tolerance work. It is a standard choice for machinists, tool and die technicians, and production drilling setups where hole accuracy and tool life are priorities. The 118-degree point angle suits general-purpose entry into a broad range of workpiece materials listed above.

Key Features

• Solid carbide construction for extended tool life in abrasive and hard materials
• 0.238 inch diameter with tight tolerance of +0.0000 to -0.0005 inches
• 118-degree faceted drill point for accurate self-centering entry
• Web-thinned parallel web reduces cutting thrust and improves chip flow
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Screw machine length body for added rigidity and reduced deflection
• Bright/uncoated finish suitable for use with or without cutting fluid

Compatibility

Designed for use in drilling cast iron, non-ferrous metals, and plastics. Fits standard drill chucks and collet systems accepting a straight-cylindrical shank in the 0.238 inch diameter range. Part of the M.A. FORD Series 206 screw machine length carbide drill lineup.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools. Ensure the drill chuck or collet is fully tightened and the workpiece is securely fixtured before initiating a cut. Inspect the cutting edge for chips or wear before each use, as carbide is brittle and can fracture if run in an improperly set up machine. Follow machine tool manufacturer guidelines for spindle speed and feed rate when using solid carbide tooling.
