Review on Thread Kits 3221 M12F Repair Kit by Dushawn Walker

Revainrating 1 out of 5

Drilled and tapped an aluminum head like I did.

I have drilled and tapped an aluminum head as I have done dozens of times but this was my first time with this brand. This will be the last time I try to insert inserts into the insert tool by pulling them out. I have never had as many problems as I have with this brand and have been doing this for over 30 years.

Pros
  • Tools and Equipment
Cons
  • Doubtful
