M.A. Ford CXDCS 0690AP Cyclone Xd 6.90 mm coolant-fed double-margin drill

SKU CH-SXB6-C29SD

Coolant-fed double-margin drill with a 6.90 mm diameter for precise hole-making

  • 90 mm diameter drills precise holes
  • Coolant-fed design clears chips efficiently
  • Double-margin construction improves hole straightness
  • Cyclone Xd geometry extends tool life
  • California Proposition 65 warning applies

Application

The M.A. Ford CXDCS 0690AP Cyclone Xd is a 6.90 mm coolant-fed double-margin drill designed for precision hole-making in demanding materials. It serves machinists and manufacturing engineers who require accurate, repeatable results in production environments.

Coolant-fed operation

Through-tool coolant delivery enables consistent chip evacuation and temperature control at the cutting zone. This interface supports deeper drilling cycles without Peck cycles, though maximum depth is constrained by the 3X diameter design intent and machine spindle capability.

Upgrade path

The double-margin geometry replaces single-margin drills when hole straightness and surface finish are critical. The step is justified for high-value workpieces where rework costs exceed tooling investment, but unnecessary for shallow holes or softer materials where standard drills perform adequately.

Questions about this item

Which diameter should I select for a 6.90 mm hole?

The drill is manufactured at 6.90 mm; choose this size when the finished hole must match that dimension.

What does the 3X coolant-fed rating mean during cutting?

It indicates the tool can run at three times the diameter depth with internal coolant delivery for chip evacuation and heat control.

How does the double-margin design affect hole quality?

Two guiding margins improve alignment and surface finish by supporting the drill at two points along the flute length.
