Was very easy to use

Used to drill holes in kayaks for rod holders so I didnt need anything expensive. Did the job!

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.

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.

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.

For a product like this you rarely use it. I wanted holes in my desktop to hide my computer wires. I have a cheap power drill and it worked, but a better quality drill is going to be needed if you need to drill a bunch of holes. To drill four holes it was a strain. The bits held up pretty well considering they were going through hard wood and the laminate on both sides about three quarters of an inch thick. You have to drill slowly so the sawdust cleans out as you go. It took probably 10-15 minutes for four holes. I would probably consider these disposable because by the fourth hole it was slow progress. I suspect the bits were beginning to dull. At the price it wouldnt be worth resharpening, but they did the job I needed.
