M.A. Ford Cyclone Xd 8X Coolant Fed Double Margin Drill 3.90mm

3.90 mm Cyclone Xd 8X Drill

The M.A. Ford Cyclone Xd 8X is a coolant-fed double margin drill with a 3.90 mm cutting diameter. It is designed for precision holemaking in production environments where consistent coolant delivery and hole straightness are critical. Machinists running high-volume jobs will value the rigid double-margin construction. The tool suits CNC operations that demand repeatable accuracy at depth.

Double Margin Build With Internal Coolant

The double margin geometry provides four-point land contact to stabilise the drill and improve hole finish. Internal coolant channels feed fluid directly to the cutting zone, aiding chip evacuation and thermal control during extended cycles. This layout reduces the risk of wandering in deep holes and supports longer tool life in abrasive materials. The shank fits standard holders for quick changeovers.

Upgrade From Standard Twist Drills

The design replaces conventional twist drills when hole tolerance, surface finish or depth-to-diameter ratio exceed their capability. The jump is worth it when coolant-through capability is available on the machine and the application demands straighter holes with less rework. Shops without through-spindle coolant or those drilling only shallow holes will not realise the full benefit.
