Micro-Tuff drill for precision holes
The M.A. Ford Twister Micro-Tuff drill creates 0.55 mm diameter holes in a variety of materials. Machinists and hobbyists use it for intricate component fabrication and detailed repair work. Its specialised geometry supports accurate chip evacuation in tight spaces. The tool arrives new and ready for immediate use in a drill press or handheld driver.
Low cutting forces reduce heat and noise
Sharp edges and polished flutes limit friction during normal drilling cycles. Operators experience quieter performance compared with standard twist drills of similar diameter. Reduced thrust lowers power draw on the driving motor. The design helps maintain consistent hole quality without excessive thermal buildup in the workpiece.
Sustained drilling keeps dimensions stable
During extended production runs the drill resists premature wear at the cutting lips. Hole diameter remains within tight tolerance across multiple parts. Chip packing stays minimal even when feed rates are maintained for long periods. California Proposition 65 warnings apply to chemicals present in the product.

Questions about this item
How do I install the 0.55 mm Twister Micro-Tuff Drill in my drill press without snapping the shank?
Chuck the drill gently using a collet or precision keyless chuck rated for sub-millimetre shanks; over-tightening a standard three-jaw chuck is the step that cracks the carbide.
When will the 0.55 mm cutting edges need replacement?
Replace the drill once the margins show rounding or the flute colour shifts to blue-grey, indicating the micro-grain carbide has lost its edge geometry.
What limit appears first when drilling repeated 0.55 mm holes in hardened steel?
Chip evacuation becomes the bottleneck; the narrow flutes pack quickly, so peck every 0.5 mm and use high-pressure coolant to maintain tool life.
