I have noticed that greenlee knock out sets we use are actually not labeled for use with Stainless Steel and that they actually have a different product for use with stainless steel. Is there a reason for that? do the ones designed for SS last longer or create a cleaner cut?
The regular ones we use only last about 150 (wild guess) holes before they seem worn out and we replace the cutter part because they are putting lips on the holes instead of just cutting though.
Is there a reason to switch to the more expensive ones designed for stainless steel?
