Review on Buwico Spiral Thread Compound Metric by Doug Hook

Revainrating 1 out of 5

First use and tapping 6061 with cutting fluid

First use and 5mm tap in 6061 with cutting fluid. If I wanted low quality products I would spend $3 more and go for HF. Don't waste your money on them. You may think it will be quick. It's not because I now have to remove the broken tip, re-drill and then hammer it in by hand.

Pros
  • Parameters: overall length 58mm, blade length 28mm, handle length 30mm, universal square handle 6.35mm.
Cons
  • Obsolete
