Any suggestions on removing Spikes quickly (cutting heads off) counter-sunk with iso plate, can't really get to shank of spike.. electric bolt cutters ??
We usually drill them out
This is what I recommend.
In the past, I have used a pick axe, with about a three foot handle. It might also be called a "Maddox", or something similar to that.
Use the flat end. You give it a good swing and they chop right off.
You may be able to chop them right through the insulation, depends on what type of insulation.
