DiabloGeneral Purpose Bi-Metal Hole Saw Set - Fits with Snap-Lock Plus Mandrel System - 10 Saw Cups, 1 Snap-Lock Plus Mandrels, 1 Pilot Bit, 2 Adaptor Nuts - DHS14SGP

Excellent set. There were a number of key factors in selecting this set. All details are worth the upgrade for my uses. First, there are a lot of sizes of holes, and I use and need this much variety. Second, the quick change is very useful, many times better than the old systems of screwing on and off the blades. Third, and a detail I was eager to have, the multiple levels of "pry" spaces on the sides. When I had my old circle saws full I had only one place to pry. Now I can pry all the way up with those notches. It is a great idea, very useful and takes out the frustration. Teeth size is not too aggressive, nor so small that they clog up. All the parts are very sturdy and well made. Nice handy case - easy to see, easy to replace.Thank you Diablo. Well done and at a good price. Buy something good, pay once. Bravo!

Good size collection. Durable, nice case. Use on commercial jobs. Easy to find replacement saws at local Home Depot.

I love theseNo issue making holes in my eaves for running lights and ethernetThey have made quick work of the wood they have encounteredThe ease of changing the bits is greatRemoving the cutout from the bit has been easy, either using the center bit to pop it out or using the side channels.I wish I had bought these a while ago. But I own them now and am very happy with them

This set is so nice when you need to drill several sized holes or when you need to drill a lot of same sized holes. The snap in feature is awesome! You can pop off one hole saw and exchange it for another in a second. Like other Diablo cutting tools, it's sharp and long lasting.The design makes extracting the plug super easy, which is something that's not so easy with other hole saws.There are 2 reasons that I gave it 4 stars instead of 5:1) The pilot bit is a little hard to remove. So hard that I thought I was doing it wrong, but when I looked it up, I could see that it wasn't the case. I'm guessing it will loosen up with more use.2) I had to send my first one back b/c the small compartment for the accessories that is inside the main case was broken. They should make that internal compartment more stout b/c w/o it the accessories will rattle around inside the main case. The main case is very nice though. Very stout and rigid and I like that you can see into it.

Mt product came in good shape but even if the case was broken these hole drills are far far better than all the others, the quick exchange mandrills and adapter nuts are so fast and easy to change sizes that no other vendor has anything close!

Hi! As a GC I’m almost daily punching a hole through something it seems. For me, the right tool is one of the most important aspects of my job. I’ve tried and trusted this brand for many years. I’ve bought almost everyone of these holes saw bits individually multiple times. So when I seen this kit, I had to jump on it.I like how there’s empty spots for my other bits as now I have one place for all of them. Well, most of them. We use much bigger ones as well but not as often. This is an outstanding kit that will work for the vast majority of situations. In my experience, These bits last as well as every brand I’ve ever tried. If not better.Hope this is helpful.

I looked at hole saw sets for quite a while and decided to spend a few extra bucks on this Diablo set. Well worth it!The teeth on the Diablo set cut very fast, I was using a small Milwaukee M12 drill and was able to cut easily through my wood project, i'm sure with a larger 18V battery drill it would really blast thru. The way the saws are cut on the side makes it easy to extract the wood plug created, they are done in 3 stages.The holes cut are VERY clean and smooth and barely require sanding. Make sure if you can to drill from the opposite side one the pilot bit makes it through. The pilot bit and the saws are a bit spring loaded and will pop off when you change them.The Case is very nice and locks tight and there is an inner compartment for the pilot bit. If you needed to get more bits there is extra room to keep them in there.Very happy!

good
