Silver twist drill bit with double flutes and coolant hole, 31/64 inch diameter

M.A. Ford

M.A. Ford Cyclone Xd 3X Coolant Fed Double Margin Drill 31/64

SKU CH-D7BF-VCSGV

A coolant-fed double-margin drill bit sized 31/64 for deep, accurate holes

  • Coolant-fed design clears chips efficiently during deep drilling
  • Double-margin construction improves hole accuracy and tool stability
  • Cyclone Xd geometry reduces cutting forces for smoother operation
  • 31/64 inch diameter suits precise hole-making applications
  • California Proposition 65 warning indicates regulated chemical content

M.A. Ford Cyclone Xd 3X Drill

The M.A. Ford Cyclone Xd 3X is a coolant-fed double margin drill built for precision holemaking. Its 31/64 inch diameter suits metalworking tasks that demand tight tolerances and consistent chip evacuation. The tool arrives new and ships directly from the manufacturer.

Targeted at CNC operators and production engineers

This drill serves shops running high-volume drilling cycles where through-coolant delivery extends tool life. It is not suited for hand-held use or machines lacking coolant-through-spindle capability. Buyers needing a different diameter or a non-coolant design should look at other options.

31/64 inch capacity with 3X geometry

The 31/64 size handles medium-diameter holes in steel and alloy workpieces with stable cutting action. The 3X length-to-diameter ratio provides reach for deeper features while the double margin design supports hole straightness. Coolant pressure and machine rigidity ultimately define the practical depth limit.

Questions about this item

What size drill chuck is required for the 31/64 inch shank on this Cyclone Xd drill?

The 31/64 inch shank fits any standard 1/2 inch or larger drill chuck that accepts straight-shank bits.

Can this double-margin drill be used in a non-coolant CNC spindle that I already own?

Yes, it will cut without through-coolant, but the internal coolant channels are designed for high-pressure coolant delivery to maximise chip evacuation.

How can I confirm the drill is cutting correctly after installation?

Check for consistent chip formation, steady spindle load and hole diameter within tolerance; the double-margin design should produce a smooth finish without chatter.
