Precision Micro Drill

The M.A. Ford Twister Micro-Tuff Drill No 79 is a specialised cutting tool designed for creating extremely small holes in demanding materials. It targets machinists, toolmakers and maintenance engineers who require reliable performance on micro-scale drilling tasks where standard jobber drills lack rigidity and precision.

High-precision micro drilling

This drill suits professionals producing pilot holes for taps, wire EDM start holes or intricate component features in hardened steels and exotic alloys. It is not intended for general-purpose drilling in soft materials, high-volume production runs requiring coolant-through tooling, or applications needing diameters larger than the No 79 size.

Consistent micro performance

The Twister Micro-Tuff geometry maintains centre cutting accuracy and resists deflection during extended use in tough alloys. The design reduces walk at the entry point and delivers repeatable hole quality across multiple operations without the rapid edge breakdown common in conventional micro drills.
