Now What?

[Snowtractor]

..Hi Richard. Guess I should have said that there is a set on sale in the princess auto sales flyer. The extractor you tap in, not pound, does not taper like the square extractors and the reverse screw type and therefore doesn't expand the bolt. It has mulitple , very small, lands on it that cut small grooves on the inside of the bolt. Each one not having enough grip to turn out the bolt but by having many of them it is very solid in the bolt. It acts like the newer slip yokes with mulitple small grooves instead of having just six honking lugs, the result is more suface contact though a 35 spline looks sno much more fragile it is infact tougher.
I have to reiterate that those reverse grooved drill bits work wonders to in removing bolts. Just slow steady pressure and out they pop very often.
