Twister Micro-Tuff Drill No 41

The M.A. Ford Twister Micro-Tuff Drill No 41 is a precision cutting tool designed for small-hole drilling tasks. It suits machinists, maintenance technicians and hobbyists who need accurate results in metal, plastic or composite materials. The drill arrives new and ready for immediate use in compatible chucks.

Upgrade from worn or undersized drills

Replacing a dull or incorrectly sized drill with this No 41 model restores hole quality and reduces cycle time when the previous bit cannot hold tolerance. The jump is worth it whenever the existing tool shows chatter, wandering or excessive burr formation on the workpiece. No specific predecessor model is identified in the data.

Questions about this item

What size chuck or collet does the No 41 drill require?

The No 41 drill fits standard collets and chucks sized for its shank diameter; check your tool holder for the matching micro-drill capacity.

How is the Twister Micro-Tuff drill installed and what step is often missed?

Insert the drill fully into the collet, tighten evenly, and verify run-out before cutting; skipping the run-out check causes premature breakage.

When should the No 41 drill be replaced or re-sharpened?

Replace or re-sharpen when cutting edges show wear, chipping, or when hole quality and feed resistance noticeably degrade.
