M.A. Ford 0.78 mm Micro-Tuff Drill
The M.A. Ford Twister Micro-Tuff Drill measures 0.78 mm in diameter and carries part number 305M0078. It is a new power-tool accessory designed for precision drilling in a workshop or production environment. The supplier notes that orders of $75 or more ship free and the item ships directly from the manufacturer.
Suited for fine-hole drilling tasks
This drill suits machinists and technicians who need a 0.78 mm cutting tool for small-diameter work. It is not intended for larger hole sizes, heavy material removal or applications that require a different diameter or flute geometry. Buyers needing a broader range of sizes should look at other tooling options.
Behaviour under sustained use
The Micro-Tuff construction is built to maintain cutting performance during repeated drilling cycles rather than only in short bursts. California Proposition 65 warnings indicate the product contains a chemical known to the state to cause cancer and birth defects or other reproductive harm. Proper ventilation and handling practices are recommended for extended operation.

Questions about this item
What collet or chuck size is required to hold the 0.78 mm shank?
A precision collet or drill chuck that accepts 0.78 mm shanks is needed; standard 1/8 inch or 3 mm collets will not grip this diameter securely.
Can this drill be used in a standard 1/4 inch hex impact driver?
No, the 0.78 mm round shank is not compatible with 1/4 inch hex quick-change chucks; it requires a three-jaw chuck or ER collet system.
How can I verify the drill is cutting correctly after installation?
The drill should produce a clean, round hole of 0.78 mm diameter with minimal burr and no excessive heat or chatter when run at recommended RPM for the material.
