M.A. Ford 305M0084 Twister Micro-Tuff Drill 0.84 mm pneumatic accessory

Micro-Tuff drill for fine holes

The M.A. Ford 305M0084 Twister Micro-Tuff Drill is a 0.84 mm pneumatic accessory built for precision drilling in light-duty applications. It suits technicians and hobbyists who need accurate small-diameter holes without the rigidity of larger tooling. The drill is sold new and ships directly from the manufacturer. Orders of 75 or more qualify for free shipping.

0.84 mm capacity and practical limits

At 0.84 mm the drill handles thin sheet metal, plastics and soft composites where a standard twist bit would wander or break. The Micro-Tuff geometry resists deflection in shallow passes but reaches its limit in deep holes or hardened alloys where chip evacuation becomes difficult. Users should expect reduced tool life when feed rates exceed the flute capacity.

Replaces worn micro drills in pneumatic setups

This accessory replaces dull or broken micro drills in existing pneumatic handpieces, restoring clean entry holes without changing collets or air supply. The jump is worth it when the old bit shows chatter, oversize holes or excessive burr formation. Note that the product carries a California Proposition 65 warning for chemicals linked to cancer and reproductive harm.
