What os the difference between time-sert and helicoil. I already have a helicoil kit so was hoping to get away with that.

your helicoil kit is for fixin stuff all the time, whereas the threadcert, or time cert is like the bob the builder replacement.

the helicoil tap will be near impossible to get without buying a kit, whereas the threadcert uses a standard size tap
