Review on TOLESA Carbide Cutter Stainless 4 (32mm): Superior Cutting Performance for Precision Jobs by Carl Morgan

I bought this for my husband to drill a hole in our stainless steel sink to make room for a water filter I was planning to put in. It fits his Ryobi drill and does the job perfectly. Lots of tiny shards of steel are left around the hole, so be VERY careful. The size was accurate. The hole was a little sharper than I expected but my husband said it was fine. All in all a good tool. Worth having the sink hole I wanted.
