COMOWARE Hole Saw Kit for Wood- 16 Pieces 3/4’’-5’’ Full Set in Case with 1pcs Hex Key, 2pcs Mandrels and 1pcs Install Plate for PVC Board Plastic Plate Drilling Drywall and Soft Wood

This is a nice collection of hole saw sizes. The attachments are solid and fit well together. The assembly for a particular cut is easy and the hole dimensions are precise. Hoping that the description was understating the material, I tried to cut through a maple desktop for a new 2 grommet to access additional peripheral computer wires. The cutting was laborious as the wood was dense and very hard. It took about four minutes to drill the one hole. I stopped repeatedly to clear the hole of the ultra-fine sawdust and to cool the hardware. One interesting note, the depth of the 2 saw-bit was too shallow to allow a full cut through the desktop. The maple is a true 1 hard-rock maple. The 2 drill bottomed out. I was able to crawl under the desk and, using the pilot hole that had penetrated, finish drilling the remaining 1/16 from the bottom. The description from the seller is accurate. The hole saw works great on soft material -- plywood and sheetrock are easy. I should have given it a 4.5 because I was influenced by my own off-label task.

The only thing that was missing was the standard diameters. Close size is good enough for most jobs.

Ive only made onw size hole and made 4 of them and it srill cuts, I dont expect it to make 100 cuts

Not a good buy for any practical utility. May be ok for thin plastic. The drill bit had trouble getting through a 1.5 inch pine board. I used a 7/32 drill bit to pre drill. The 1+1/2 inch hole blade wasnt very sharp. The saw dust wasnt being ejected out, despite pulling it out every 1/8 inch or so. I ran my drill at half speed and paused every 30 seconds (hoping not to build up too much heat). I thought maybe I wasnt spinning fast enough to get the sawdust out of the teeth so I speed it up. The wood started smoking (of course) so I stopped. When I ran the drill in reverse (slowly) to pull out the hole saw, the drill bit broke (see pictures). Also, the depth of the saw is a hair shy of an inch (so getting through a 2x4 takes two passes). Just thought Id iterate that here because it didnt help my frustration (I fully take responsibility) . Reading it and experiencing it are two different things.

Got the job done, but not a tool youre going to want to use more than once or twice. Not sharp at all and the precision on the hole size isnt great. Cheap and takes a bit of elbow grease. Id imagine itd be great on something softer, like drywall.

The bit for the hole saw broke after about 5-6 uses. Its cheap so I didnt expect much, but still, the bits are so brittle that they should give you two. Especially since they dont use a standard sized bit.

I purchased to cut a 5 in hole in a soffit. 3/4” thick. If u start too slow all the teeth will catch. Maybe enough to break the tool? I don’t know but i started to slow and the teeth caught and instantly stopped the drill. So i started with a faster rpm and was able to cut all the way without catching or stopping. Worked for what i needed it for.

These will cut threw soft wood but that’s about it. If you try and use anything else they will just burn the wood or just bind up. Good for the price though.

This would not be a good set for constant or commercial use. However, for the price it is a great set for the occasional need of several different hole sizes. Easy to switch from one size to the other and a very compact case that doesnt take up much space.

They work well
