Twister Micro-Tuff Drill 2.05 mm

The M.A. Ford Twister Micro-Tuff Drill is a precision pneumatic accessory with a 2.05 mm cutting diameter. It is designed for high-speed drilling in composite materials and hardened alloys where standard tooling wears quickly. The tool suits aerospace, automotive and precision-engineering shops that require consistent hole quality and extended tool life.

Replaces worn micro-drills and carbide alternatives

When existing micro-drills dull rapidly or produce oversize holes, this Twister Micro-Tuff Drill restores process control. The jump is worth it when a shop runs high-volume micro-hole operations and needs reduced tool-change downtime. The 305M0205 model targets applications where conventional high-speed steel or standard carbide drills fail to hold tolerance.

Suits CNC operators running micro-hole patterns

This drill fits CNC machines and pneumatic spindles that accept 2.05 mm shank tooling. It is not for manual drilling, large-diameter work or environments where Proposition 65 listed chemicals are prohibited. Buyers needing coolant-through capability or different shank configurations should look at other tooling lines.

Questions about this item

What chuck size accepts the 2.05 mm shank of this Twister Micro-Tuff drill?

Use a chuck that closes fully down to 2.05 mm; a standard 3 mm or 1/8 inch collet will not grip this shank securely.

How do I install the 305M0205 bit in a pneumatic drill without snapping the micro shank?

Insert the bit until the shank seats fully, then tighten the chuck by hand before applying air pressure; over-torquing the jaws is the common cause of breakage.

When should I replace the 2.05 mm drill if it shows no visible damage?

Replace it once the cutting lips wear enough to increase thrust force or produce rough holes, as micro drills lose precision before they visibly dull.
