Precision Micro Drill for Fine Holemaking
The M.A. Ford Twister Micro-Tuff Drill No 39 is a miniature cutting tool designed for creating very small holes in metal and other materials. It suits machinists, toolmakers and maintenance technicians who require accurate drilling at micro diameters. This accessory fits standard drill chucks or collets on milling machines, lathes or portable drills.
Heat and Wear Management in Normal Use
The Micro-Tuff coating and geometry reduce friction at the cutting edges, limiting heat buildup during high-speed operation. Lower temperatures extend tool life and help maintain hole size consistency across repeated cycles. Efficient chip evacuation prevents packing that can increase torque and noise. The design supports stable performance without excessive power draw from the machine spindle.
Drill Size No 39 Determines Fit
The single specification that decides suitability is the No 39 wire-gauge diameter; the drill cuts a hole matching that specific size only. Buyers needing a different diameter, a larger step size or a non-standard tolerance cannot use this part. The California Proposition 65 notice also indicates the presence of listed chemicals, which may affect material-handling procedures in some facilities.

Questions about this item
How do I install the No 39 Twister Micro-Tuff Drill in my drill chuck, and what step do people often get wrong?
Open the chuck fully, insert the drill shank completely, and tighten securely; the common mistake is not seating the shank all the way before tightening.
What maintenance or replacement will the No 39 Twister Micro-Tuff Drill need later?
Inspect the cutting edges regularly for wear or damage; replace the drill when it no longer cuts cleanly or shows visible dulling.
What limit appears first on the No 39 Twister Micro-Tuff Drill during sustained use?
Heat buildup at the cutting tip is the first limiting factor; allow cooling periods to maintain cutting performance and tool life.
