JB Tools offers bottoming taps designed to cut threads to the bottom of blind holes with maximum precision. These taps feature minimal taper at the tip, making them ideal for finishing threads that starter or plug taps can’t reach.

A critical tool for pros and DIYers needing full-depth thread engagement.
