Thread Cutting Kit 1/2” x 8 tpi
Each kit contains a screw box for cutting the male thread and two taps, a starter and bottom tap for cutting the matching female thread. These kits will cut threads on most firm timbers.
Recommended pilot holes for female thread are 1/8" less than diameter. i.e. For 1/2" drill 3/8" hole.
For male threads, turn the shaft to comfortable fit in the screw box. Rubbing some wax or hard soap on the timber will aid the screw box.
Timber to be tapped can be held in a vice or chuck in a lathe if you have a means of locking the spindle, but NOT with the lathe running. If you do decide to hold it in this way, be safe and turn the lathe off at the mains before starting, as it is so easy to hit the start button in error.
Images below show male and female in use, bench vice and timber not included.
