Precision micro drill

The M.A. Ford Twister Micro-Tuff Drill 30500700 .0070 is a new power tool accessory manufactured by M.A. Ford. It is intended for precision drilling tasks where a very small cutting diameter is required.

For fine-detail work

This drill suits machinists and hobbyists who need to produce extremely small holes in metal or composite materials. It is not suited for general-purpose drilling, larger hole diameters, or high-volume production where standard twist drills would be more efficient.

Micro diameter capacity

The .0070 inch diameter defines the cutting capacity and provides minimal material removal per pass. It handles delicate features and tight tolerances comfortably but runs out of rigidity and chip clearance in deeper holes or tougher alloys.

Questions about this item

What drill chuck size is needed to hold the .0070 inch Twister Micro-Tuff Drill?

A precision chuck or pin vise that can grip a .0070 inch shank is required; standard drill chucks typically cannot hold such a small diameter securely.

Can the 30500700 drill be used in a standard cordless drill driver?

Only if the driver accepts micro-diameter bits; most standard chucks bottom out well above .0070 inch, so a dedicated micro-drill or pin vise is usually necessary.

How can I verify the 30500700 drill is cutting correctly after setup?

The drill should produce a clean, round hole with minimal burr at the rated feed; excessive heat, wandering, or rough walls indicate incorrect speed, feed, or tool wear.
