13.70 mm coolant-fed drill

The M.A. Ford CXDCR 1370AP Cyclone Xd is a 13.70 mm diameter drill designed for coolant-fed drilling operations. Its double-margin construction provides enhanced hole straightness and surface finish in demanding materials. This tool targets machinists producing deep holes where consistent coolant delivery is critical. It is not suited for dry machining or applications lacking through-tool coolant supply.

Double-margin stability under load

The double-margin design maintains alignment during extended drilling cycles, reducing wander as the tool penetrates deeper. Coolant channels flush chips continuously, preventing packing that can increase torque and heat in long holes. This geometry supports sustained performance where single-margin drills might deflect. The tool requires a machine spindle capable of delivering coolant at adequate pressure.

Coolant-fed interface constraints

Effective use depends on a coolant-through spindle or holder that matches the drill's internal passages. Insufficient coolant pressure or volume will compromise chip evacuation and tool life in deep-hole drilling. The shank must be held securely in a compatible holder to prevent slippage under cutting forces. Machines without through-spindle coolant cannot utilise this drill as intended.
