M.A. Ford Twister XD 10.50 mm Drill

The M.A. Ford Twister XD is a 10.50 mm coolant-fed drill built for production drilling in tough alloys. It targets machine shops and maintenance teams that need repeatable hole quality without manual lubrication. The 5X length suits deeper holes in a single pass. It is not for buyers who want a hand-held bit or a short general-purpose twist drill.

Coolant-fed drilling limits

Coolant-fed operation removes heat and chips from the cut zone, but the machine must supply pressure and filtration that match the tool diameter. Without adequate flow the flute can pack and the drill may wander or break. The 10.50 mm size demands a spindle and holder that can deliver the required volume. It is not for machines that lack through-spindle coolant or external flood capability.

Installation and common issues

The drill fits standard holders for its shank type; secure it with minimal run-out before starting the cycle. Verify coolant passages are clear and pressure is steady at the tip. The most common problems are insufficient coolant pressure, worn holder collets and incorrect feed rates that cause chipping. It is not for set-ups that cannot check run-out or maintain constant feed.

Questions about this item

Which Twister XD 5X Coolant Fed Drill diameter should I select for a 10.50 mm hole?

The 2XDCR4134A model is manufactured at exactly 10.50 mm, so it matches that hole size directly.

What does the 5X designation mean for drilling depth in practice?

It indicates a flute length up to five times the 10.50 mm diameter, allowing deeper holes in a single pass.

How does the coolant-fed design affect chip evacuation and tool life?

Internal coolant channels flush chips from the 10.50 mm cutting zone, reducing heat and extending drill life.
