9.40 mm Solid Double-Margin Drill

The M.A. Ford Cyclone Xd 3X is a solid-carbide drill with a 9.40 mm cutting diameter and a double-margin design for improved hole straightness. It targets machinists and maintenance teams who need accurate holes in steel, cast iron and similar alloys.

Double-margin geometry and solid carbide body

Two margins guide the tool in the hole, reducing wander and improving finish without a separate reaming pass. The solid carbide construction resists wear at higher cutting speeds, while the 3X length-to-diameter ratio suits through-holes up to roughly three diameters deep.

Check shank fit and coolant provision

Verify that your holder or collet accepts the drill’s shank diameter and that your machine can deliver coolant through the tool or via external flood. The product carries a California Proposition 65 warning for chemicals linked to cancer and reproductive harm, so ensure appropriate handling controls are in place.

Questions about this item

What shank standard does the 9.40 mm Cyclone Xd drill use?

It uses a straight round shank sized to the 9.40 mm diameter, so it fits standard drill chucks that accept that metric size.

What chuck capacity is needed to hold this 9.40 mm drill?

A chuck that opens to at least 9.40 mm is required; the drill has no reduced shank, so the full diameter must be gripped.

How is the double-margin drill installed in a CNC turret, and what step is often missed?

Insert the shank fully, align the flute start with the turret face, then torque the holder — operators often skip the flute-alignment check.
