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

Bought this to fix the previous plumbers laziness. Had to poke a hole though a 2x4 then 1/2 osb and as all home improvement projects go just a sliver of floor joist. Mounted the size I needed chucked it up on the trusty 20v lithium drill and let it eat. Cut through the 2x4 like butter. Once I got to the osb we were making heat like jet engine exhaust. Pop through the osb and find that edge of the joist and thats when the going gets tough. See between the osb and 2x4 I had some high quality 1997 era linoleum, super heated linoleum makes it near impossible to remove the slug you just cut. This is where I have issues with the tool, everything prior is my fault and the previous guy who took the easy road. I took the saw off the chuck, mind you its somewhere between 150 and the surface of the sun in temp. Once I clear the mess and go back at it the nut will not stay tight, had to let it chill on the window sill here in the December midwest to finish the job. Overall it worked, 2nd hole was just osb so that was a walk in the park. For what you pay it does well.

The set does everything I need it to do. I have cut the 7 holes I needed to get done, and they all went easily. BUT... like others, I wish the smaller pilot would fit a 3/8 drill. Like others, I had to use a 1/2 drill for every hole, whether the small pilot or the larger pilot. So it missed 5 stars throughout simply because a few thousandths on the small pilot made me use a much larger and heavier drill to drill a 3/4 hole. The saws cut well... low speed, cutting oil for the metal, and no discoloration or loss of edge that I could see.

I read many reviews, and I went for it. There are cheaper sets, however I liked the case design so I went with this. I used the 1-1/4 bit a lot making holes in plastic 55 gallon drums for a rain barrel project. One of the reviews mentioned that they needed a socket to remove the arbor from the hole saw bit. I hope that person hit it with his purse fist, that usually loosens them. Here is an easier way, remove the bit, loosen the grub screw, then put a smaller screw driver through the side holes and remove the hole saw bit. Not hard right? That is because its not hard! Are there better bit locking designs? Yes, in this kit when you use the larger arbor its an easier design to remove it. Some reviews you need to understand the authors skill level.

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.

Was very easy to use

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.
