Precision Micro-Drill for Fine Holes
The M.A. Ford Twister Micro-Tuff Drill measures 0.47 mm in diameter. It is designed for machinists and technicians who need to create extremely small, accurate holes in metal or composite materials. This accessory fits standard power and pneumatic tools used in detailed fabrication work.
Proprietary Geometry Improves Tool Life
The Micro-Tuff flute design reduces cutting forces and improves chip evacuation in tight bores. That geometry change lets the drill run longer without breaking or wandering, so operators spend less time replacing broken tools on delicate jobs.
Solid Carbide Construction Withstands Heat
The solid carbide body resists wear and heat buildup during high-speed drilling. A standard shank allows direct clamping in common collets or chucks without adapters. California Proposition 65 warnings apply because the material contains listed chemicals.

Questions about this item
When should the 0.47 mm drill be replaced?
Replace the drill when the cutting edges show visible wear or when hole quality degrades, as the 0.47 mm diameter leaves little margin for resharpening.
What limits continuous drilling with this bit?
Heat buildup in the 0.47 mm cutting zone is the first limit; the small diameter evacuates chips slowly, so sustained use requires frequent peck cycles.
How much heat does the drill generate during all-day use?
The 0.47 mm flutes concentrate cutting heat, so the bit and workpiece warm quickly; use coolant and short drilling intervals to manage temperature.
