Review on Efficiently Tackle Hard Metal Projects With Aiyun'S 6-Pack Metric Drill Tap Set For Steel And Aluminum by Randy Basque

Revainrating 2 out of 5

Only Good for VERY soft Aluminum or Plastic - Waste of Time on Mild Steel

Used to tap 6mm threads on 10 ga mild steel and got one hole threaded using slightly larger bit first.

Bit snapped on second hole using smaller guide hole and the bit on this for sizing. Didn't make it past the 3rd thread using my Ryobi drill on slow speed setting and clutch set at 50%.

Pros
  • Works really well. Smooth drill in and out no problem.
Cons
  • To small
