Micro-Tuff Drill No 100

The M.A. Ford Twister Micro-Tuff Drill No 100 is a precision cutting tool designed for creating small-diameter holes. It suits machinists and technicians working on detailed fabrication or maintenance tasks where accuracy matters.

Check shank compatibility

Verify that your drill chuck or collet accepts the shank dimensions of the No 100 tool before ordering. Confirm the workpiece material matches the drill's intended cutting range to avoid premature wear or breakage.

Steady cutting under load

The Micro-Tuff construction resists deflection during extended drilling cycles. It maintains consistent hole quality and tool life when used at appropriate speeds and feeds for sustained production runs.
