2 inch hole saw worked really well - though I had to borrow an electric drill with a 1/2 inch chuck from a neighbor. (Both of my drills had only a 3/8 inch chuck.) It looks like most of the hole saws require a drill with a 1/2 chuck. This hole saw has the 2 protrusions that stick out and lock it into place. Not all of the 2 inch saws have that, but it is a good idea. It cut through both sheet rock and house siding very easily.

I purchased this bit to drill holes through oak for LED pick light installation. It did the job quickly, cleanly, and accurately. No complaints whatsoever.

Nice product with good quality and value. Great price for a hole saw with included arbor and extra bit. The only negative was the depth. Why would you fabricate a saw that was NOT deep enough to cut thru 2x material when listed as 1-1/2†deep…the dimension of the overall depth OUTSIDE. I find it strange that manufacturers do not think about how their products may actually be used and design for that. I needed this to cut thru a joist.That said, it performed well and appeared to be of good quality.

I needed this hole saw to cut two holes in our Murphy bed for spot lights. The saw ran smooth and true in my cordless drill running at a slow and steady pace. The substrate was 3/4-inch thick hardwood plywood, the cut was clean, and the blade did not experience dulling. At least for limited DIY work, this hole saw delivered great value for me.

This is the worst hole saw I’ve ever seen. It’s so out of round that my hole that should have been 1 3/8†is actually almost 1 1/2â€I didn’t use it until just after the return window closed so only just saw it. It’s going in the trash as it’s completely oval. Useless waste of money 😞

Its 1st job was drilling a 5" hole through 4" of hard wood (old house); it did the job and held up to the force of a powerful Milwaukee Magnum drill.I rarely buy Chinese tools, but considering that many US brands make their drill bits/blades there, I took a chance on a no-name Chinese brand without the name brand price. It's well made, it perforned, and the teeth are still sharp.NOTES:- It's important to tightened the locking ring on the included arbor to prevent it from unscrewing from vibration and releasing the two locking rods. Mine wasn't tight enough and it unlocked during the 1st hole. Screwing the locking ring firmly in place prevented this from reoccurring.- It doesn't have the clean-out and debris holes/channels cut through the sides, so it can jam more frequently when buried in wood if you don't stop to clean it out a few times while cutting deeper holes.- The absence of side holes in the barrel makes it a bit more difficult to remove cut material stuck inside. That is, you can't stick a screwdriver in a side hole to push out material lodged inside, you must do this from the front of the bit.

I ordered this hole saw for cutting holes into plywood for some projects I am working on. Works fantastic and the quality is exceptional, when you consider that buying one at a local hardware store is 4 times more expensive…..this is a great deal!!

dieser 49mm Bohrer macht erstaunlicherweise 49mm Löcher. Rund, keine "Eier". Ein Ersatz-Zentrierboher und der Inbus sind dabei. Der abgebildete 2. Halter ist nicht dabei, aber wozu auch.Ich bin zufrieden, ich kann wirklich brauchbare Löcher machen (Holz und Kunststoff getestet).

I can't say it's any better than it's rivals, it cut quickly and cleanly as a hole saw should.
