Review on QLOUNI Concrete Cement Cutter Connector by John Clark

I bought these because I needed to drill TWO holes in a brick wall to clear a 2" DWV pipe and saw no point in buying a durable, high quality drill saw if that's all what i need them for Perfect fit, BTW. Now I can't use it much anyway as it has a huge defect and I can never fix and rebuild the pilot bat if it breaks. The pilot is held in place by a machine screw as an adjusting screw. I imagine how not smart it is to go around a broken brick with a rotating hole saw. Of course it broke immediately. Of course I was too stupid to replace it with a socket head screw. Do not be so. Swap out the bolt head machine screw and you can use this bit well enough for casual use without paying five times as much for a professional version, even through brick with a hole punch that only draws about six amps.
