A slug buster is also known as a knockout punch. I got the set from Harbor Freight
. It is a cheap set but I understood what I was getting into when I bought it. What I mean is my Bayou Classic kettle
is thin so I figured if this set lasts for the 4 holes I need it for it would be worth it. I wasn't going to pay $100.00 for two Greenlee punches that I might never use again. At least with the set, if they last, you have four different sizes for $25.00. The 3/4" knockout is already showing signs of fatigue with 3 holes cut. These work best if your starter hole is just slightly larger than the bolt. That way the cutter is precisely centered in the hole (Very Important). I wouldn't use this punch set on anything thicker than this thin kettle because they just wont hold up. A step drill will work but you have to have a good grip on the drill and your kettle held sturdy.
Nonetheless, the punch did cut through the thin stainless with relative ease so I can recommend it for just this purpose. It might leave a bit of a burr but is easily ground off with a Dremel or any such grinder.
