💯 MAGBIT 628-7216 Carbide Hole Saw, 16 inches Review

Poor quality. Bought this hole saw to clean out the existing concrete light holes around our pool. I only used it for about 5 minutes and on the 2nd hole the metal heated up and the teeth melted inside - absolutely nothing to cut. wasting $40.

This drill bit cuts through very tough 1 1/2 inch plaster/lathe like butter. Apart from the paint on the drill, it's still like new, ready for another hole. I used it to cut a hole for a bathroom fan outside the house under the eaves. You can't find anything like it at this price. Trust me I've searched the internet and many commercial and residential sites.

We bought an old house with very thick (nearly 1 inch) thick stucco trim. We installed a couple of lights on the front using another hole saw. It took about three hours to drill each hole. We needed to drill another hole for a bathroom vent and the model we were using wasn't that size so we bought this one. It's a bit more expensive. But it was worth it! The hole for the plaster was drilled in about 10 minutes. It took a little longer to pierce the wood, but this is for concrete, not wood, so…
