Twister Micro‑Tuff Drill No 102

The M.A. Ford Twister Micro‑Tuff Drill No 102 is a precision cutting accessory built for power and pneumatic tools. It serves machinists and maintenance technicians who need a reliable small‑diameter drill for accurate hole‑making in metal and composite workpieces.

Upgrade from standard jobber drills

This drill replaces general‑purpose jobber bits when tighter tolerances and longer tool life are required in micro‑drilling operations. The step up is justified for repetitive high‑precision tasks where standard bits wander or wear quickly.

Prop 65 chemical notice applies

California Proposition 65 warnings indicate the product contains substances linked to cancer and reproductive harm. Users must follow safe‑handling practices, use appropriate ventilation and personal protective equipment, and dispose of worn bits in line with local regulations.

Questions about this item

What drill chuck size accepts the No 102 Twister Micro-Tuff drill bit?

The No 102 bit fits standard chucks that hold its shank diameter; match the chuck capacity to the bit size before tightening.

Which step do users often miss when installing the 30500390 drill bit in a power drill?

Users often forget to fully seat the bit shank in the chuck jaws before tightening, causing run-out or slippage during drilling.

When should the No 102 Twister Micro-Tuff drill bit be replaced?

Replace the bit when cutting edges show visible wear, chipping, or when drilling requires noticeably more force than when new.
