“Fed up using hole saw on electrical panels and this makes the perfect hole even upto to 2 mm enclosures. It only says 1.6 mm but I had no trouble and no need for thrust bearings, just copper grease.”
“Needed to cut holes in stainless steel box for electrical push buttons. Although it's not meant for stainless it easily cut through with no issue and cut over 20 holes.
Excellent product.”
