Review on 🔩 Uxcell A15012200Ux0296 Carbide Drill Stainless: Superior Performance for Stainless Steel Drilling by Cameron Reed

I had high hopes for this hole saw. The threads of the set screw that secures the guide jet are not fully threaded through the jet hole. I can't even attach the pilot head to test the product. Quality control error! I could finish a tool for a manufacturer; but I don't want to find and buy a metric tap to fill in blind threads. Instead I buy a much more expensive brand name tool to do the job.
