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 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

I used this to cut holes for recessed lighting. I was cutting through old plaster board which would quickly wear out any ordinary hole saw with conventional cutting teeth on it. So far I have cut about a dozen holes and it is still cutting as good as new. Keep in mind that if you don't have an arbor to mount it to your drill, you'll need to get one. Also, it is a good idea to catch the mountain of dust that will result from cutting in your ceiling. I bought a $5 basketball, cut it in half, cut a hole in the bottom of the half and mounted it to the saw & arbor assembly. Works like a charm!

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.

Great blade but makes a lot of dust. Get a bowl type dust collector, you'll be glad you did. I have cut 16 holes and the blade is still strong. Try a Morris Products 13500 Drillers dust bowl. I was cutting through plaster and it worked great.

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.

This is by far the best big hole saw I've ever used. I really like that it doesnt have actual teeth. Usually when cutting drywall holes, I have to run the saw backwards. Not with this one. Since there are no teeth to bind, it doesnt catch and stutter start. Totally worth the $$$.

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.

Good hole saw. But don’t drop it. It bends very easy
