Silver cylindrical drill bit with two parallel flutes, 7.90 mm diameter

M.A. Ford

M.A. Ford CXDSR 0790AP Cyclone Xd 5X Double Margin Drill 7.90 mm

SKU CH-2GSX-C0XVV

A solid double-margin drill with 5x diameter depth capacity for 7.90 mm holes

  • 5X diameter drilling depth for deeper holes in one pass
  • Double margin design improves hole straightness and surface finish
  • 90 mm diameter suits precise metric drilling tasks
  • Cyclone Xd geometry optimises chip evacuation in tough materials
  • Solid carbide construction resists wear for longer tool life

7.90 mm Double-Margin Drill

The M.A. Ford Cyclone Xd 5X is a solid-carbide drill with a 7.90 mm cutting diameter and double-margin geometry for improved hole straightness and surface finish. It targets machinists and maintenance technicians who need accurate deep-hole capability in a single pass.

Five-times-diameter reach in one tool

The 5X length-to-diameter ratio allows drilling depths up to five times the nominal diameter without pecking, reducing cycle time and freeing the spindle for other operations. It fits standard tool holders and requires only adequate coolant pressure and rigid workpiece clamping to perform as intended.

Steels and cast irons up to moderate hardness

The solid-carbide construction with proprietary coating handles carbon steels, alloy steels and grey cast iron comfortably at recommended speeds and feeds. It is not suited for hardened steels above typical heat-treated ranges, non-ferrous alloys that demand specialised geometries, or applications requiring through-coolant channels not present on this model.

Questions about this item

How does the 7.90 mm diameter affect chip evacuation during deep-hole drilling?

The 5X flute length and double-margin design on the 7.90 mm Cyclone Xd drill improve chip control and hole straightness in deep drilling applications.

Does the solid carbide construction run hot enough to need coolant through the tool?

Solid carbide handles heat well, but flood or through-spindle coolant is recommended for 5X depth cuts to manage temperature and extend tool life.

What tool holder is required to grip the 7.90 mm shank securely?

A precision collet chuck, hydraulic holder or shrink-fit holder sized for 7.90 mm shanks provides the run-out control needed for this solid carbide drill.
