Rannb Hole Saw 3-inch Dia Hole Cutting Drill Bit for Drilling Holes in Wood, Plastic, Drywall, Thin Metal

Used for gutter downspouts.

Great product, would buy again.

Just what I needed. It worked for a simple job with plywood. I wouldn't recommend this for heavy contractor use it's more of an occasional specialty tool. Take a look at my video. The drill is missing an essential locking mechanism between the threaded drill shaft and the hole saw plate. Be careful with this thing. It's big and as Newton said remains in motion.

For temporary use? It's great... for everyday use no.... the set screw included that locks in the bit.?.. it strips easy...if you have extra set screws to spare.. this is reliable.. I used this for cutting through exterior housing panels...

This hole saw cut a beautiful round hole, in thick plastic, wallboard, and plywood almost effortlessly. It is very sharp. It feels heavy, more so than the cheap blades I previously had in my tool chest. The replaceable center drill bit worked well, and I was pleased to find this hole saw came with two extra replacement drill bits AND with the hex wrench to use when the bit needs replacing. I plan to find other diameter hole saws by this manufacturer. Don't worry about this being made in China. It is NOT a cheap tool, as some Chinese exports are.

Q les puedo decir de esta broca es una locura si quieres poner un juego de luces nuevas en tu casa y no tienes los agujeros en tu silin esta es la broca perfecta para esas luces

Reviewing the Rannb 90mm/3.5inch hole saw. ---------------------------------- PLUS: Diameter is very accurate. This hole saw comes with a shank that fits my 1/4 inch drill. ---------------------------------- MINUS: Not very sharp out of the box, and gets duller quite quickly. Cutting through 3/4 inch baltic birch plywood, the saw started "grabbing" about 1/4 inch into the first cut. Reducing the downward pressure to a minimum helped, but it still took about 2 minutes to cut the first hole. Second hole took longer, and by the time we were at hole #7 it took about 5 minutes to cut through. By then the blade was so dull that it was basically grinding through the wood (as opposed to cutting). The sawdust was very fine, about what you would expect from #220 grit sandpaper. Also, what looks like anodized coating on the bit turns out to be paint, which burns off from friction (with attendant pleasant burned-paint smell). ---------------------------------- OVERALL: A cheap bit that worked for the intended purpose of cutting 7 holes, with probably 3 or 4 holes left before the bit goes into the trash. If you need a bit for a small number of holes, and are willing to drill very slowly, this would be a reasonable choice given the price tag.

Will work great

Used it for cornhole boards in 18mm ply. Perfect for the job.

Dulled out very quickly and was almost unusable before the job was finished, I was using it in drywall. Its ok if you only have one or two holes to make.
