Hole Saws

For those cutting up Stainless Steel 1/2 bbl kegs for brew kettles, the "Bi-Metal" hole saws from Home Depot suck.  They won't even cut one hole.  The ones from ACE Hardware that look the same and cost pretty much the same work great! Hole after hole, keg after keg, no complaints.  The only difference I can see are the ACE ones say "Made in U. S. A." on the side.  Home Depot were from China.
