Micro-Tuff Drill 0.21 mm pneumatic accessory

The M.A. Ford 305M0021 Twister Micro-Tuff Drill is a 0.21 mm pneumatic accessory designed for precision hole-making. It suits engineers and technicians who need very small diameters in controlled workshop environments. The drill is supplied new and ships directly from the manufacturer.

Check pneumatic supply and tool holding

Verify that your pneumatic system can deliver the pressure and flow required for micro-diameter drilling. Confirm that your chuck or collet accepts a 0.21 mm shank without run-out. Review the California Proposition 65 notices regarding cancer and reproductive-harm chemicals before use.

Replaces worn micro drills in high-precision work

This drill replaces dull or broken micro drills when hole quality and dimensional tolerance are critical. The jump is worth it when existing tooling no longer holds size or produces excessive burrs on fine features. Orders of $75 or more ship free from the manufacturer.

Questions about this item

What comes in the box with the 305M0021 drill bit and do I need to buy a collet separately?

The box contains the 0.21 mm Twister Micro-Tuff drill bit only; a compatible collet or chuck for your pneumatic tool must be purchased separately.

How do I choose between the 0.21 mm size and other diameters in the Micro-Tuff range?

Select the 0.21 mm version when your application requires a hole of that exact diameter; each size in the range is sold individually for a specific hole size.

What does the 0.21 mm diameter mean for real-world drilling in hardened steel?

It produces a precise 0.21 mm hole in tough materials such as hardened steel, suited for micro-drilling tasks where standard bits would wander or break.
