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.

Worked great for tapping my AlphaOne Gen1 bell housing for shifter cable change.

Threading in new shift cable without cleaning old housing thread is frustrating- this inexpensive, specific sized, thread cutting tool makes quick work of worn or dirty housing thread.

How do you review a tap? I needed a SPS (straight thread pipe) tap to finish modifying a lamp. I didn't want to pay the national debt of a 3rd world country to get one. It tapped the hole through 1/4" steel just fine, and I expect it'll tap quite a few more if needed. Not often that I need a straight VS tapered pipe tap. Quick delivery.

I used this to retap a Mercruiser pre-alpha gimbal housing (actually the bell housing) so that the shift cable could be installed from the outdrive side. The manual calls for a 1/4 - 18 NPSF (National Pipe Straight Fuel) which is microscopicly different but this worked just fine. Just coat the threads of the shift cable with Permatex Aviation form-a-gasket (Mercury's replacement for their Perfect Seal sealant) and you should be all good.

This tap did a good job in creating threads for a pipe plug that I needed.

Worked like a charm to tap to install a pressure gauge. Didn't use a tap wrench like you're "supposed" to. But it worked out perfectly fine. Will be part of my tools collection.
