Micro-Tuff Drill No 84

The M.A. Ford Twister Micro-Tuff Drill No 84 is a new power tool accessory built for precision drilling tasks. It suits machinists and maintenance technicians who need a reliable small-diameter cutting tool. The drill carries manufacturer part number 30501150 for easy identification and reordering.

Drill size No 84

The single specification that decides fit is the No 84 drill designation, which defines the exact cutting diameter. Select this item only when your drawing or tap chart calls for a No 84 drill; any other size will not match the required hole tolerance.

Sustained cutting behaviour

Under continuous use the Micro-Tuff construction resists wear and maintains cutting geometry longer than standard twist drills. The design reduces work hardening in the workpiece, helping to preserve hole quality during extended production runs. California Proposition 65 warnings apply for cancer and reproductive harm.
