Roll Form Thread Repair

Roll Form Taps- used to pressure form threads in softer material like aluminum.
Roll form taps are used to “restore” damaged threads.
They work well because they will actually push the metal back to shape as opposed to cutting it away.
Word of caution: they use a lot of force and are way easier to break so don't get to western with them.
Use plenty of oil and steady pressure.
Turn in 2 or 3 turns, back off 1 or 2 turns to allow the pressure to come off and if you are using a cut tap the cut material needs to come out.
Another word of caution, when you buy cheap taps and dies, sometimes you get what you pay for. 3)
