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

The product worked well for drilling through vinyl siding and wood...nice clean hole.

They are not the fastest bits I have ever had. The <2 bits allow you to use the drill bit to remove the wooden puck after drilling without much issue. They do not clear themselves of dust when drilling so I woudl suggest you remove them every so often to allow for less binding up. They are not going to last a long time form what I can tell but take up little space and are organized for a few small projects.

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.

I shouldn’t be surprised considering how cheap this is. Even so it baffles me a little how quickly it tore up and broke from regular use. The FIRST time I used it. The pilot hole bit snapped in half and the center piece that fits in the drill chuck broke. The blades seem fine. So I’m just going to replace the center bit and keep rolling.

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.

VFM for light DIY usage

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.

This is a light duty kit. Will cut through sheetrock, soft wood, thin wood over and over again. Anything heavier will wear it down at the fastening hole. Will only cut heavier woods twice before giving out. If you get more than two hd cuts... your doing good. Ok kit for light dulty use

Used this to go through asphalt shingles in the roof to put in a vent. If I had more than a couple to do, there would have been a problem as the tool was chewed up. For softer plywood, the quality would be fine.

Depth of circular attachments doesnt exceed 1/2 in. Also drill bit is poor, needs to be replaced with one thats pointier.
