M.a. Ford. 22621650 Solid Carbide Screw Machine Drill Bit

Product Description

The M.A. FORD. 22621650 is a solid carbide screw machine length drill bit designed for high-precision drilling in demanding shop and production environments. With a 0.2165 inch (5.50 mm) diameter and a 118-degree faceted drill point, it delivers clean entry and consistent hole geometry. The short flute design and parallel web configuration contribute to rigidity and reduced deflection during drilling. A web-thinned tip reduces thrust requirements at entry. This bit is suited for machinists, tool-and-die professionals, and production drilling technicians working with close-tolerance applications.

This drill bit is built for use in CNC machining centers, drill presses, and manual lathes where short, rigid tooling is preferred. It is rated for drilling cast iron, non-ferrous metals, stainless steel, and steel. The 3xD flute-to-diameter ratio makes it well-matched for shallow-to-moderate depth holes where chip evacuation is not a limiting factor. The straight cylindrical shank accepts standard drill chucks and collet systems. It conforms to DIN 6539 specification, making it compatible with metric-standard tooling setups common in precision manufacturing.

Key Features

• Solid carbide construction for rigidity and heat resistance in tough workpiece materials
• 118-degree faceted drill point for self-centering entry and reduced walking
• Web-thinned tip reduces cutting thrust and extends tool life
• Bright/uncoated finish suitable for use with or without cutting fluid
• Right-hand spiral flute with regular helix for standard chip evacuation
• Meets DIN 6539 specification for consistent dimensional accuracy

Compatibility

Designed for use in standard drill chucks and collet holders accepting a 0.2165 inch straight cylindrical shank. Rated for cast iron, non-ferrous metal, stainless steel, and steel workpiece materials. Conforms to DIN 6539.

Installation Notes

This tool is installed and operated by machinists and production drilling technicians. Secure the shank fully in the chuck or collet before operation and verify runout with a dial indicator on precision applications. Use appropriate cutting fluid for stainless steel and cast iron to manage heat buildup. Inspect the cutting edges for chipping before each use, as carbide tooling is brittle and sensitive to interrupted cuts or side loading.
