Was very easy to use

These are not bad at all. Only reason why people keep saying it became dull is because they overheat the bits. Probably not using it with impact drill. I used it with regular drill and it worked perfect. I used it on my desk. I just had to do it for a few seconds, then spray some water and repeat. It came out great. It took about 10 minutes to drill the 1 inch thick desk because after about 2 minutes, it gets really hot. I had to dip it in cold water. If you dont cool it down and keep going, teeth will become dull due to heat

I bought this to drill holes for plastic grommets for my desk to try to better organize my cables and not have to stretch them over the edge. The desk is typical engineered particle board and I wanted a reasonably priced hole saw for this. It works and does a nice job overall, but it takes a lot of patience to cut through even marginally thick engineered wood. I dont know if the saw blades will old up over time, but it works if you have patience. I also found the 2 hole saw still made a slighter bigger whole than the 2 grommets I bought, but it wasnt a show stopper for my project. I drilled the pilot hole first and then started the hole with the hole saw on both sides hoping to prevent splintering on the underside/inside of the hole and that worked well.

Drill a hole, and it wor

The battery dies in my Barska gun safe and they gave me the wrong emergency key. I pulled out my hole saw and I was in my safe in 5 minutes and the hole saw is still cutting like a champ. Doesn’t say much for Barska but these hole saws are great.

I purchased this item to cut a hole in a 1/2” round wooden board to to use as a small umbrella table for my patio. The product does not come with directions, however, it was fairly easy to figure out, and Im in my 60’s. Worked perfectly and Im very happy with the result.

I used just one size to drill holes to make a rain barrel. I dont know quality-wise how long theyll last because I wont use it much. Thats why I deducted one star.
