Silver twist drill bit with coolant holes, 10.90 mm

M.A. Ford

M.A. Ford Twister XD 7X+ Coolant Fed Drill 10.90 mm

SKU CH-3PR1-7VZ37

Coolant-fed drill with 10.90 mm diameter for deep-hole drilling applications

  • Coolant-fed design clears chips efficiently during deep drilling
  • 90 mm diameter suits precise hole-making tasks
  • Twister XD 7X+ geometry enhances cutting performance
  • M.A. Ford construction delivers professional-grade durability
  • California Proposition 65 warnings inform safe handling practices

Application focus

The M.A. Ford Twister XD 7X+ is a coolant-fed drill built for 10.90 mm holes. Internal channels deliver cutting fluid directly to the tip for heat control and chip evacuation. It suits CNC and high-volume metalwork where through-tool coolant is available.

Upgrade path

This drill replaces standard twist drills that rely on flood coolant or peck cycles. The step is justified when cycle time, hole straightness or tool life on deep holes become limiting factors. The 7X+ geometry targets difficult alloys and cross-hole intersections.

Fit and alternatives

Machinists running controlled coolant systems on tough materials will benefit. Shops without through-spindle coolant, or those drilling shallow holes in soft metals, should look at conventional solid-carbide or HSS drills instead.

Questions about this item

What shank diameter fits the 10.90 mm Twister XD drill?

The 10.90 mm Twister XD drill uses a 10.90 mm shank, so the holder or collet must accept that exact diameter.

How do I connect coolant to the 2XDCL4291A drill?

Feed coolant through the machine spindle into the drill’s internal coolant channels; the common error is running it dry.

When should the 10.90 mm Twister XD drill be replaced?

Replace it when the cutting edges show visible wear, chipping, or when hole quality and diameter tolerance fall outside specification.
