Hole saw kit recs

Been eyeing some kits on sale, or will probably come on sale over Xmas time. Intended mostly for 'the brown stuff' but maybe softer alloy metals like aluminum based on some examples I've seen which actually surprise me. I'm kind of a Milwaukee fan boy but one of the kits on sale has some so-so reviews. My main criteria is to be able to buy replacement parts or saws if I burn them out, or maybe an in between size if not in the kit. That's where some product lines are not quite as plentiful. KMS sells Milwaukee & also Diablo. I see a Bosch set... Lennox was a good name back in the day but not as common? Any recommendations?
 
I’m a big fan of the Diablo and Lenox hole saws.
I used a Lenox hole saw to drill the 1-1/8” bearing holes in the counter shaft bracket for my lathe. Two holes, zero issues and it’s still good for many more I’m sure.
 
I've had no complaints with my Milwaukee set. I like that it has 2 arbors. One straight threaded for the smaller diameter saws and another with push in tangs to hold the bigger saws and stop them from getting too tight. Used mostly for wood and occasionally sheet metal or metal clad doors. A few times for 1/4 or 1/2 inch plate. I've collected a couple or Irwin carbide tooth hole saws from PA in the mystery boxes, 2 3/8 and 4 1/2 inch and they fit the same arbor.
 
Milwaukee or Lennox, I've got both and the stand up well. Mostly used wood, plastic, and aluminum but have used the Milwaukee on 316 stainless with decent service life.
 
Going to surprise some here with this recommendation. Hole Saw set from Amazon
I needed a hole saw to cut a metric opening in steel, and saw I could get this set for the price of an arbor and single saw from Home Depot. Worked great getting though sheet steel (20 gauge maybe). 2 complaints - the provided set screws that retain the pilot drill are made of cheese and need replacing. And there is no organizer for them, each is individually packaged. For the price I'm happy. For wood to make nice clean holes I prefer a Forstner bit over a hole saw unless its going to be really big, like 3" plus, then I'll just pony up for a specific hole saw but those are usually construction jobs so the finish isn't usually a concern.
 
i have had pretty good luck with lennox

i wouldnt buy a set, just a good arbor and sizes as needed, you're going to end up with a bunch of sizes you will never use if you buy a set
 
Yes, I thought about buying what I need which would start with smaller diameter sizes anyways. When I started to tally the components individually, it was exceeding the kit price. Maybe because of kit sale. But like you say, if you never use them... I'll have to study this. I suspect the bigger arbor is required after a certain diameter.
I thought the Bosch only used one arbor but seems to me there was a comment that 'a part was missing'. Once upon a time in the store I played with some parts. Some looked interchangeable, others not

the arbor with the two pins and the screw collar is for the larger sizes, both kits have that. The smaller hole saw sizes just screw on, it looks like that Milwaukee one has the separate arbor, the Bosch one may just do it with a bushing.

98$ for that set its a very good price, i dont know how well they preform in steel for that price. I have found with hole saw's price is pretty much directly linked to performance
 
I just started noticing that term 'pack out'. Does that mean the containers nestle to one another & you can go even crazy with a cart?

I have a few of each major brands, and most are good. Lubrication and cooling is extremely important to getting life out of holesaws. Even soapy water will extend the life of a holesaw 10x over dry cutting. They build a lot of heat.

That said, carbide tipped holesaws are incredible.
 
Milwaukee has been good to me. You can get “master” sets on sale every once in awhile. I bought mine like 5 years ago. Have to replace a few now and then but only after some harsh use in steel.
 
Starrett, Diablo, Milwaukee are a few that I have that I would recommend. I actually have a mastercraft maximum set that is pretty good quality. The others I acquired because I needed a particular size and had to drill a lot of holes with them. That's the tradeoff, and if I had to do it over again I'd do it the same way. Buy a large cheaper Bi-Metal set of a variety of sizes, and If I found myself needing better quality in specific sizes, buy that size in a high quality name brand.

You can always nurse a lower quality hole saw through a need it now project for a couple holes, but having an expensive set of a variety of sizes sitting unused in a case for me is a waste of money. Unless you get a great deal on it!
 
I was ready to click buy on Milwaukee 9-pc set which is closer to my current sizing needs. KMS & others have good sale prices. Lots of replacement & incremental Milwaukee sizes to choose from, carbide, diamond etc . I don't really care about the box. So those are all Milwaukee positives. Dismissing reviews like case quality beefs or obvious tool abusers, I'm reading too many bad reviews on saw quality, roundness, arbor fit... more fundamental QC things that are kind of cooling my jets right now. Normally I'm a Milwaukee fan boy. Diablo might win out. Their arbor system seems a bit simpler? TBC.

I just went off on a price search, and the prices for the ones you linked above are really no different and sometimes cheaper than was you'd get at Can tire for maximum stuff (at full price, not CT's notorious jacked prices and perpetual sales). My advice above doesn't math out in this case. The Diablo, or Milwaukee kits above are decent deals, and you'd probably be splitting hairs between them as to quality.
 
Or just go straight to carbide? Some of the carbide kits/sizes reflected on Diablo web site are not offered (no carbide at KMS). Or kit varies wit CDN sellers (HD mixing bi-metal with carbide). Anyways Diablo carbide are out there in the wild. The more I look, the more I kind of like their adapter system more which I have a feeling might be part of the Milwaukee complaints (ie. arbor runout centering issue vs cup roundness, but really not sure)
