Blue Boar Recessed Light Carbide Grit Hole Saw 6-3/8” Dia for 6 inch Lights: Fast Cutting in Drywall, Lath & Plaster, Hardi Board

This thing is great. I was a little skeptical bout it once I got it. But we’ve used it a lot since having it. It cuts nice 6” holes in plaster and drywall. Clean and without chips or cracking the plaster. I cut about 40 holes with it and it’s still working fine. Quick, clean, and easy.

We used this to cut 16 6” holes for remodel cans. Our ceiling consists of 2 layers of drywall and the original lathe and plaster underneath those. Our old house was certainly unconventional but this worked perfectly and the size was perfect! It took a strong drill and made some serious heat and started to warp a little towards the last holes. It could do a few more holes if needed. Id say its good for at least 20-22 holes in our 3 heavy layers. If it was just drywall? 40-50 easily could be done, maybe more.

I had to cut holes for 9 recessed lights in Armstrong ceiling tile - the type that's used in a grid. This worked very well on a hand-held portable drill. The cuts were reasonably quick, with very clean edges. The open back makes i easy to push the cutouts out of the hole saw. There was no discernible wear, although cutting just 9 holes isn't ,much of a test. For wallboard, ceiling tile and similar panels when you're installing recessed lighting, this is a much less expensive alternative that buying a bi-metal saw-toothed 6-3/8" hole saw.

I bought this product it worked really great. But after using it for a bit. Not sure why the saw got bent. It still did the work, but made the hole a little bigger than it suppose to. Advised the company of the issue. They were great on responding back to me about the issue and were able to either refund me or send me another. I requested another hole saw because it works great. Received the replacement item in 2 days. I recommend this product for recess lighting.

This thing is amazing. I bought this for installing 6" recessed lights. It cuts 6 3/8 holes which is perfect for 6" can lights. Not only that, once I had this in my hands I was very impressed. This thing is a solid chunk of steel. A nice feature is the open back, so you can knock out your piece of drywall etc, that you have cut out. Here's the interesting part: I have so far used this to install 20 lights. The ceiling I installed these in had wood lathe, plaster and drywall. This thing gave me perfect holes every time. 12 more lights to go, and I know I will have no trouble because there are no signs of wear in the carbide surface. Don't get a regular toothed hole saw, especially for going thru wood lathe. You need that lateral (sideways) abrasiveness to get a nice clean cut. Took 4 battery charges on my Makita 18 volt full size lithium battery drill to get all of these holes cut. I paired this with the MK Morse M45P Hole saw arbor and it was a match made in heaven. Add the Disston E0215000 RemGrit Hole Saw Dust Bowl, and I'm pretty sure that will save your marriage. I hate spending money on tools I will probably only use once, but I think I'm going to install recessed lights in every room due to my experience with these items.The hole saw arbor I used: https://www.amazon.com/dp/B000E8BFIO/ref=cm_cr_ryp_prd_ttl_sol_0The dust bowl I used: https://www.amazon.com/dp/B00ESWJU5W/ref=cm_cr_ryp_prd_ttl_sol_2

Got this to install flat recessed LED wafer lights, worked perfectly! I have "rock lathe" plaster, which is basically just hold drywall with plaster on top. This went right through 8 times so far and doesn't seem to have dulled yet! I do recommend a dust catcher though, since you're basically grinding the material to dust, it makes quite the mess.

OK, I try to be fair on reviews and I didn't see it in the description or on any of the other reviews but "fits standard arbor" is subjective. I have two sizes of Harbor Freight hole saw kits and neither arbor fits this saw. So before I bought this I debated whether to cut six holes with a saber saw or buy a saw. This one seemed the least outrageous (I know carbide is expensive, the toothed ones were ridiculous for what they are) and it was right at the dollar point that I thought, ok, what the heck, I'll probably never install recessed lighting again before I croak but at least it will be easier and professional. Now that I have to buy another arbor, I'm feeling a little put out. I wouldn't have bought it if I knew I needed another arbor. So maybe everyone else on earth has the "standard arbor" that fits this saw but I didn't. The saw itself seems to be made well enough, I just wouldn't spend $10 per hole for 6 lights.

I bought this with the dust bowl collector and it makes cutting holes into drywall really easy. A perfect fit for my recessed lights.Also, I learned the hard way but you need the arbor to grip onto drywall otherwise the bit will jump everywhere and make a hole bigger than you want. Maybe this is common knowledge, but I didn't know!!I tried enlarging an exisiting hole that had a 4-inch diameter to make it 6-inch and the bit went everywhere! Make sure you use this over a fresh patch of drywall. Otherwise, you may need to put a woodblock in the middle of the exisiting hole so the arbor can grip.
