Heli-coil questions

Dennday67 no i wasnt using any fluid at all, the cause of the tap breaking i guess... My stupid fault.. Ive drilled through both taps and easy outs. On my brother in laws tri-power 6 in his mustang, he had snapped the bolts off for the water pump. He asked me to fix it, but when i seen it, there wasnt any material to grab onto or weld a nut to turn it out. Worst of all, he broke an easy out, from napa in one of the snapped bolts... I drilled through the eazyout, and the bolt, then tapped the holes again, bamm good as new lol.. Again same "borrowed drill bits" from dad. I have also drilled through a 1/2" caterpillar bolt, it took about 30-40 mins, but i did it lol. where can i get those ez locks you mentioned?
