Tips

  • Machine taps are suggested to be used with tap collets with overload protection. Hand use or electric drills use is easy to cause breakage to the tap, so it is not recommended.
  • Use with tapping oil to get higher quality thread and more durable taps. Cutting oil is lubrication, cooling and anti-sticking. Be sure to select the appropriate cutting oil for complex tapping process and apply anti-rust oil for maintenance after use.

A left handed tap is a hard thing to come by. To get one delivered to me in a few days, quite a good one, is just amazing. And it’s a left handed plug tap, just what I needed.
