Bought to drill 1 2” hole through basement wall and it broke. Threads stripped out and set screw wouldn't stay in.

Equipment is good, just have a hammer on hand to break tight hold on hole saw piece. This might be caused by paint heating on screw grooves, after used a few times that could change. This do not have bolt holding points so you can take it off with wrenches. You need to know to go though wall you need to drill pilot holes with 12" masonry bit. Then use DEHUIWI bit don't go pass bolt holding bit.

This product is sweet It comes in a self contained case. Have enough material to cut through cement blocks and Small core samples. If drilling through thicker concrete use water to keep the tool cool but it will cut cement guaranteed. I am very happy with this product

The kit is nice. I’ve drilled through concrete slabs of 3” depth with no problem. Let an electrician borrow it and he managed to break a tooth off the small bit but whatever. Biggest size is about 5” which is perfect for 4” cast iron pipe. Will follow up in about a month for longevity.Update: they still work great. The drill bits fall out pretty easy if you don’t tighten them in well enough, but these are still a great product

I didn’t expect much for $40 but these bits worked really good. I drilled through 4” of 8,000 psi concrete with no issues at all. I can tell that after 10 holes they have some wear but no issues at all. Best bits for the price.
