Twister Micro-Tuff Drill No 43

This M.A. Ford drill is a precision cutting tool for fine-hole applications. It targets machinists and technicians who need accurate small-diameter drilling in metal or composite materials. The No 43 size suits detailed fabrication and maintenance tasks.

Replaces worn or undersized micro drills

Swapping to this drill is worthwhile when an existing bit no longer holds tolerance or when a job demands the specific No 43 diameter. The Twister Micro-Tuff design supports consistent performance in repetitive precision work.

Check spindle fit and material compatibility

Verify that your tool holder accepts the shank configuration used on this micro drill. Confirm the workpiece material matches the drill's intended cutting range. Note the California Proposition 65 warnings for chemical exposure.

Questions about this item

What size drill chuck does the No 43 Twister Micro-Tuff drill require?

The No 43 drill has a very small diameter and needs a precision chuck or collet that can grip micro-tools securely without runout.

How should the Twister Micro-Tuff drill be installed in a high-speed spindle to avoid breakage?

Insert the drill fully into the collet, tighten evenly, and verify concentricity before starting; the step most often missed is checking runout at operating speed.

When does the No 43 Twister Micro-Tuff drill need replacement during production use?

Replace the drill when the cutting lips show wear, chipping, or when hole quality and dimensional tolerance fall outside specification.
