10.40 mm Cyclone Xd drill for precision holes

The M.A. Ford CXDSS 1040AP is a solid double-margin drill designed for 3x diameter drilling depth. It targets machinists who need accurate hole placement and improved surface finish in a single operation. The 10.40 mm cutting diameter suits applications requiring this specific size.

Double margin design improves hole straightness

Two margins guide the tool through the workpiece, reducing drift and improving roundness compared to single-margin drills. This geometry also helps maintain alignment when drilling through cross-holes or angled surfaces. The solid construction supports consistent performance in steel and cast iron.

3x diameter depth limit defines reach

The drill is engineered for holes up to three times its 10.40 mm diameter, restricting its use to shorter holes. Deeper holes require a different length series or peck-drilling cycles not covered by this tool's design. California Proposition 65 warnings apply to chemicals present in the product.

Questions about this item

How often should the 10.40 mm double margin drill be resharpened?

Resharpen when cutting edges dull or hole quality drops; the double margin design maintains alignment longer than single-margin drills, extending intervals between regrinds.

What limits continuous drilling with the 10.40 mm Cyclone Xd?

Chip evacuation in deep holes is the first limit; the 3X length increases chip packing risk, so peck cycles or through-coolant are needed to sustain feed rates.

How much heat does the 10.40 mm drill generate in all-day production?

Heat builds with speed and feed; the double margin reduces friction by guiding in the hole, but sustained high RPM without coolant will raise workpiece and tool temperature.
