Cyclone Xd 5X Drill 8.50mm

The Cyclone Xd 5X is a solid double margin drill with an 8.50mm cutting diameter. It is manufactured by M.A. Ford for precision holemaking in metalworking applications. The tool targets machinists and maintenance technicians who need accurate, repeatable results.

Sustained load behaviour

The solid construction and double margin design support stability during continuous drilling cycles. This geometry helps maintain hole straightness and surface finish when the tool remains engaged for extended periods. Heat distribution is managed through the tool body rather than through specialised coatings.

Practical interface limits

The 8.50mm shank fits standard collets and holders sized for this diameter. California Proposition 65 warnings apply because the product contains chemicals identified by the state as carcinogenic and as reproductive hazards. Users should follow applicable safety regulations when handling or machining with this drill.

Questions about this item

Does the 8.50 mm drill generate noticeable heat or vibration during prolonged use in a drill press?

The solid carbide construction and double-margin design help dissipate heat and stabilise the tool, reducing vibration and temperature rise during extended drilling cycles.

What shank type or holder does the 8.50 mm drill require to fit my existing machine?

The drill uses a standard straight shank compatible with common drill chucks and collets; no special holder or adapter is needed for typical workshop equipment.

Will the 8.50 mm drill work reliably in an older drill press with lower spindle speeds?

The 5× diameter flute length and double margins maintain guidance and chip evacuation even at modest speeds, so the drill performs consistently on legacy machines.
