Micro drill for precision holes

The M.A. Ford Twister Micro-Tuff drill cuts 0.63 mm diameter holes in metal and composite materials. It is aimed at technicians and hobbyists who need repeatable micro drilling without a dedicated CNC spindle. The tool ships new and carries a California Proposition 65 warning for cancer and reproductive harm.

Shank fits standard micro chucks

The drill uses a common shank size that clamps directly into pin vises, rotary tools and small drill presses. No adapter or collet set is required, freeing bench space and reducing setup time. Orders of $75 or more ship free from the manufacturer.

Single drill bit in bulk packaging

The package contains only the 305M0063 drill bit with no lubricant, case or software. Users must supply cutting fluid and work-holding fixtures themselves. The minimal bundle keeps cost low for shops that already stock consumables.

Questions about this item

How small a hole can the 0.63 mm Twister Micro-Tuff drill before the bit breaks?

The 0.63 mm diameter is the limit; the micro-grain carbide resists deflection but will snap if feed pressure exceeds the flute strength.

Does the 0.63 mm drill generate noticeable heat or noise during extended drilling cycles?

At 0.63 mm the cutting zone stays small, so heat build-up is minimal and the only sound is the spindle; no extra cooling is required.

What shank size must my tool holder accept for the 305M0063?

The drill has a 0.63 mm shank matching the cutting diameter, so a collet or chuck that grips 0.63 mm is needed.
