M.A. Ford Twister Micro-Tuff Drill 0.39 mm
The M.A. Ford Twister Micro-Tuff Drill 0.39 mm is a precision cutting tool designed for creating small-diameter holes. It suits engineers and machinists working on detailed component fabrication or prototype development where accuracy is critical.
Suited for micro-drilling tasks in metals
This drill suits users needing a 0.39 mm diameter tool for high-precision applications. It is not for buyers who require larger hole sizes, heavier material removal rates, or tools designed for hand-held drilling machines without rigid spindle control.
Performs consistently in controlled, rigid setups
Under sustained operation, the drill maintains dimensional stability when used with appropriate coolant and feed rates in a fixed machine spindle. It is not designed for intermittent high-load bursts or unstable machining conditions that accelerate wear on the cutting edges.

Questions about this item
What size drill chuck or collet is needed to hold the 0.39 mm shank on this Twister Micro-Tuff drill?
Use a precision collet or micro-chuck that accepts a 0.39 mm shank; standard 3 mm or 1/8 in collets are too large and will not grip this drill securely.
Will this 0.39 mm drill fit in the same tool holder as my standard 3 mm or 1/8 inch micro-drills?
No, the shank diameter is 0.39 mm, which is far smaller than 3 mm or 1/8 in holders; you need a dedicated 0.39 mm collet or adjustable pin vise.
How can I verify the drill is cutting correctly after installation?
Under magnification, the drill should produce a clean, round hole at the 0.39 mm diameter with minimal burr and no wandering at the entry point.
