9.40 mm Coolant-Fed Cyclone Xd Drill

The M.A. Ford CXDCS 0940AP is a 9.40 mm solid-carbide drill with internal coolant delivery and a double-margin design. It targets machine shops and production lines that need accurate, high-penetration holes in steel, stainless alloys and cast iron. The 3× diameter flute length suits short-hole operations on CNC centres and dedicated drilling units.

Practical limits of the 3×D coolant interface

Internal coolant channels evacuate chips efficiently up to three times the tool diameter, reducing heat buildup and extending tool life in deep-hole cycles. Double margins improve hole straightness and surface finish by guiding the drill continuously. Without through-spindle coolant capability on the machine, the internal feed cannot be used and performance drops sharply.

Upgrade from standard external-coolant drills

This drill replaces conventional twist drills that rely on flood or external coolant, eliminating chip-packing failures in deeper bores. The step up is justified when hole depth approaches 3× diameter, tolerance bands tighten, or cycle-time reduction pays for the higher tool cost. Shops drilling only shallow holes or lacking through-coolant spindles will not recover the investment.

Questions about this item

Which version of the M.A. Ford Cyclone Xd 9.40mm drill should I choose?

The CXDCS 0940AP is offered in a single 9.40mm diameter with 3X coolant-fed double-margin geometry, so there are no alternate capacities to select.

What does the 9.40mm diameter mean when the drill is in a machine spindle?

It produces a 9.40mm hole; the triple-margin design and internal coolant channels improve straightness and chip evacuation at that size.

What interface does the 9.40mm Cyclone Xd use and what does it cap in practice?

It uses a standard cylindrical shank that fits common drill holders, limiting use to machines that accept that shank style.
