M.A. Ford Twister Micro-Tuff Drill 0.71 mm 305M0071

Micro drill for precision work

The M.A. Ford Twister Micro-Tuff Drill measures 0.71 mm and suits fine-detail drilling in electronics, jewellery or model-making. Its small diameter lets operators reach tight features without excess material removal. The tool arrives new and ready for immediate use in a workshop or bench setup.

Capacity and practical limits

The 0.71 mm size handles delicate holes in thin sheet, soft metal or plastic where larger bits would wander or crack the workpiece. It runs out of rigidity in thick stock or hardened alloys where deflection or breakage becomes likely. Operators should match feed and speed to the material to avoid snapping the flute.

Upgrade path and when to switch

This drill replaces worn or undersized micro bits that no longer hold centre or produce clean entry holes. The jump is worth it when hole tolerance tightens or when a previous bit walked on hard surfaces. Buyers needing diameters above 1 mm or deep-flute clearance should select a larger tool.
