I tapped 12 holes in less than 20 minutes! The holes were already drilled but using the tool to tap threads was very easy. I wasn't sure what to expect when i ordered the set but the price was good so i took the risk. I had nothing to worry about. The tool cuts nice, sharp threads and it makes tapping even 1/4 inch steel easy. Buy with confidence.
Works great for me being an electrician. For the price you can't complain too much. Use cutting oil or spray lubricant don't over torque and keep straight and these last for several uses in mild to soft materials. I start and reverse often to clean shavings from bit to keep it from hanging up
Fantastic product and great service i am very happy with my purchase thank you.
great bits and thread hole as well
