  • New M.A. Ford Cyclone Xd tool ready for use

Cyclone Xd 8X Drill 4.65 mm

The M.A. Ford Cyclone Xd is an 8× coolant-fed drill with a double-margin design and a 4.65 mm cutting diameter. It is built for deep-hole drilling where through-tool coolant delivery and guided margins improve chip evacuation and hole straightness.

Who this suits and who should look elsewhere

Machinists drilling deep holes in steel, stainless or cast iron will benefit from the coolant-fed, double-margin geometry. Buyers who need a larger diameter, a non-coolant stub drill or a carbide end mill should choose a different tool.

Deciding specification — 4.65 mm diameter

The 4.65 mm cutting diameter is the single figure that determines whether this drill matches the hole size required by the drawing or the tap drill chart for the intended thread.

Questions about this item

How is the 4.65 mm coolant-fed drill installed in the holder, and what step is often missed?

Secure the double-margin shank in a precision collet or hydraulic holder, then verify the internal coolant port aligns with the machine’s through-spindle supply; operators often forget to open the coolant valve before the first plunge.

What maintenance or replacement will the 4.65 mm Cyclone Xd drill need during its service life?

The cutting edges will dull and require regrinding; the double-margin geometry must be restored to original angles, and the internal coolant passages should be flushed each time to prevent chip packing.

What limit appears first when the 4.65 mm drill runs at sustained 8× diameter depth?

Chip evacuation through the 8× length becomes the bottleneck; coolant pressure and flute capacity determine whether chips clear or pack, so monitor thrust force and acoustic signature for early warning.
