12.80 mm Double Margin Drill

The M.A. Ford CXDSR 1280AP Cyclone Xd is a solid carbide drill with a 12.80 mm cutting diameter and 5X diameter drilling depth capability. Its double margin design improves hole straightness and surface finish in demanding materials. This accessory targets machine shops and maintenance teams producing deep, accurate holes in steel or exotic alloys.

Replaces Single Margin or Shorter Drills

Switching from a single margin or 3X length drill is worthwhile when hole wander or poor finish scrap parts on deep bores. The 5X reach and second margin stabilise the tool through cross-holes and angled exits. Shops drilling only shallow holes or soft aluminium will not see a payback from the added length and margin geometry.

Fits Standard Tool Holders

The straight shank mounts in common hydraulic, shrink-fit or collet chucks without adapters. Run-out must be kept low; excessive holder wear or poor clamping causes chatter and margin damage. Through-coolant supply is recommended for chip evacuation at full 5X depth, and peck cycles may be needed where coolant pressure is limited.

Questions about this item

What collet or chuck size is needed for the 12.80 mm shank?

Use a 12.80 mm collet or a chuck that closes fully to 12.80 mm; the shank diameter matches the drill diameter.

How do I avoid snapping the drill when starting the hole?

Begin at low RPM with light feed, establish a full-diameter guide, then increase to the recommended speed for the material.

When should the 12.80 mm drill be replaced?

Replace it when the margins show uneven wear, the point chips, or hole size drifts beyond tolerance.
