Disston E0215002 Two-Pack Blu-MOL RemGrit Hole Saw Accessories Dust Bowl, for Installing Recessed Lights and Works with All Hole Saws

This worked perfect. I used it with my 6 inch hole saw and not a spec of dust came out.

Wow. This thing is a game changer. I’m not sure it’s wonderboard but all the “Sheetrock” in our house is about an inch thick and is very very annoying to cut through. Create so much dust and literally kills multi tool bits within mins. Because of that, when putting in led can lights it’s a royal pain to the point we haven’t completed all the fixtures we would like because of all the mess. Enter this guy. The arbor hole was bigger than my 3/8 arbor, which is a touch annoying so it didn’t fit perfectly but otherwise it worked flawlessly. Saved so much time in cleanup. Very quick to get in and get out. Soooo happy!

Will never not have one of these again. Cutting lots of ceiling light holes for a kitchen project and can't believe how well this performed compared to others I have tried. Just be careful bringing it down so you don't spill the dust everywhere.

Works as desired. My only complaint is that it’s sort of hard to find your pilot hole.

This worked perfectly to keep the dust and mess off of the floor.

Amazing. So simple yet achieves so much. Not new to recessed lighting. I have done a few before and blamed the circular saw blades for poor performance and bad holes. Little did I realize that its not the saw blades but the dust poring all over that would discourage me from continuing with the saw blades and switching to a drywall saw. Now I had a dust bowl with the Kobalt saw as well but that flimsy plastic is no match for this one. With the two washers (costing about 40 cents each, Lowes part number 63449 lubricated with pb blaster or wd40), a garabage can next to you to empty the dust each time you pull out and a pack of baby wipes to clear the haze from the silicone so you can see where you are centering is all that is needed to make nice clean holes.Even with this, I was not so confident to make a hole in one shot as I could not trust the blades. So I would pull out at least a couple times for each hole and on each pull out I would clear out the dust with wet wipes so I could see where I was placing the hole saw. End of day I would wash off the bowl with water and wipe down with a dry wipe so its like new for the next day.I used this for both 4" and 6" holes with the Kobalt 6" hole saw and the 4" Milwaukee hole saws both in plaster as well as in drywall with equally good results. I always start with the drill in reverse to get the initial marking and then put in in forward and slowly increase the pull on the trigger without pulling too hard and apply only gently pressure. If you do pull too hard or drill at high speed it could easily get jammed and twist your hand. Drilling at slow speed does take time - about 10 minutes per hole but its clean neat and painless. A garbage can nearby to empty the dust prevents secondary spills from the bowl which you always have to watch out for.

Worth the cost for one hole in the ceiling! I put 3 lights in the ceiling and had now drywall dust to clean up. Easy to use and works great.

So as with other buyers looking for the best way to cut drywall holes with minimal dust, my research brought me to this type of product. To me, a silicone and plastic bowl at this price seems a little steep, but yet strangely acceptable if it can do it's intended job properly. So here are some notes and thoughts, taking into account some great ideas from other buyers on how to successfully use:- I looked at many other bowls of the same basic design. Given that many have commented about the red plastic center piece melting and separating from the silicone bowl, I researched silicone bowls with metal center pieces. There are some available, at a cheaper price, however the opening of 10mm was not appropriate for my hole saw, which has a 7/16 inch hole saw arbor. This bowl has a 1/2 inch opening, which works with my tools. For information, I used a carbide grit-tipped keyhole saw, which cuts through drywall effortlessly.- ASSEMBLY: Taking into account the recommendations of others (1) I purchased two 1/2 inch fender washers to place on either side of the red plastic opening. I don't think the washer on the inside did much, since the forward pressure of the drill really put the friction on the washer outside of the bowl, but hey better safe than sorry. I bought the shiny stainless steel versus zinc, since to me the zinc has a rougher surface and is perhaps more prone to friction. I also oriented the washers so that any imprinted information was not on the surfaces that rubbed together; (2) I lubricated the contact faces of the washers, and red plastic, with silicone lubricant. I bought a spray version but wish I could have found a smaller non-aerosol version); (3) I placed a lubricated washer on the hole saw arbor, put the shaft through the hole, placed another lubricated washer on the shaft on the other side, and connected to my drill. The end result was a sandwiched red plastic piece.- USE: (1) Using a same sized drill as the hole saw arbor, I pre-drilled all of my drywall center hole locations. Why? Many complained of the inability to see through the bowl after the first use (more on that below), and having a drilled hole made it super-easy for me to "feel" the next location when moving between holes; (2) drilling slowly in a counter-clockwise direction, I applied light, even pressure to the drill, and popped through the drywall in no time; (3) moving onto the next hole, and to address the comments about a lack of visibility. By wiping a small area of the inside of the emptied bowl (in my case with my fingers), I could once again see the area to be cut without much issue. Coupled with the pre-drilled holes, this process became very simple; (4) after 3 or 4 holes, I quickly disassembled, cleaned and re-lubed the washers. Maybe not needed, but I felt better about ensuring the drywall dust was off the friction surfaces.My pictures show the parts and how I assembled the equipment. The last three pictures show the washer wear (closest to the drill) and both sides of the red plastic, post use. Yes, there is some evidence of wear after ten holes, but i suspect I'll get a lot more mileage out of this before it needs to be replaced.So, a great product if used properly and with some added modifications. I think the manufacturer could provide instructions and recommendations to help buyers increase the life of their purchase.
