M.A. Ford CXDSS 0420AP Cyclone Xd 3X Double Margin Drill 4.20 mm

Drill for precision 4.20 mm holes

The M.A. Ford CXDSS 0420AP Cyclone Xd is a solid carbide drill with a 3X length-to-diameter ratio and double-margin design. It is built for accurate drilling in steel, stainless steel and cast iron where hole straightness and finish matter. The tool is supplied new and intended for use in CNC machines or rigid manual setups.

Suited for short-run production and prototype work

Machinists who need a single 4.20 mm drill for low-to-medium volume jobs will find the double-margin geometry holds size well without reaming. Shops that require a full range of diameters, internal coolant feed or coated variants for high-temperature alloys should look at other tooling lines.

4.20 mm cutting diameter defines the hole size

This drill cuts a 4.20 mm hole and no other diameter. The 3X flute length and double-margin construction support straightness in that specific size, so the part number must match the hole required on the drawing.
