  • High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance
  • Titanium nitride coatings add a hard layer of gold-colored ceramic to the surface that extends tool life and permits faster cutting speeds than uncoated tools
  • Round shanks allow use with a wide variety of toolholding systems
  • When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
  • 0.625-inches thread length

This tap was just what I needed. I was tapping a shallow hole just a little deeper than the bolt needed to be. A regular plug tap didn't cut threads as deep as I needed. This one was perfect. Cut threads very close to the bottom of the hole. It was sharp and cut nice, clean threads.

This is small and sharp. Use it very slowly with a little lubricant and success!

I tried tapering the hole I had drilled, with the recommended size hole pre-drilled, the bit got chewed up and is no longer functional. Disappointed.

Love it, not a lot of holes tapped with it yet so I can't speak to tool life but love the performance.
