Review on 🔧 Bonsicoky Carbide Stainless Plastic 16-53mm by Charles Russell

I purchased this 53mm hole saw set primarily for a steel door in our church. The original hole was cut in the wrong place for a different style of doorknob. To solve this problem a stainless steel plate was fitted to cover the old hole and cut out. A regular metal hole saw couldn't cut stainless steel so I bought this set. He was able to cut through stainless steel plates. Also used a smaller hole saw for the latch.
