LANIAKEA 8-1/4-Inch Bi-Metal Hole Saw 210MM M42 Annular Hole Cutter HSS Variable Tooth Pitch Holesaw Set with Arbor Blue for Home DIYer

This tool will do its job that said it is pretty difficult to get it to work correctly you must have a very steady hand. It likes to try to dig in way too deep and get jammed up in the drywall. I don’t think this is necessarily an issue with this specific brand rather just an overall challenge with any hole cutter. I was able to cut 20 holes in my ceiling for some lights it wasn’t easy but it did work.

I use it for puck light installation and for cutting ceiling tiles. Works great

Received this as expected. Packaging was a bit ragged but all the cutters and loose parts were there (3 sets of blades). Used the hole saw to cut 4 x 8-1/4" holes in our ceiling for speakers. I used a Chicago Electric 1/2" reversible hammer drill (corded). You definitely need the side handle to control this big cutter. It's really a load on the drill cutting bigger holes. The cutter worked just fine and the price was really good.

I needed to open 8" holes in drywall for speakers.1. adjustment is very tricky to make it perfectly equal and right size2. tool is very heavy and could be quite dangerous at drill speed3. watch out for blades biting in to the material if you run them slightly off parallel to surface. it will twist your arm with force.overall it did the job but I had to fine tune it with knife and saw.

I bought this tool to cut an opening in the exterior wall of my house. It works well as long as you operate it in reverse, because the teeth will not get stuck into various materials.The tool is heavy, so it requires low speed and patience. But overall, a good value.

I allowed my to make a 6 3/8 hole in drywall. Clean cut all the way through did not tear the paper on the drywall. Good product. I used this to install recessed LED lighting in my kitchen

This tool can be useful, but in my opinion the tool is not suitable for a hand help drill. Just trying to bore an 8"' hole in 1/2" drywall proved difficult. The tool is heavy enough to overpower the drill and making it hard to control and thus dangerous.Be sure to check the tightness of the blade set screw between each hole, they can loosen up and make the bits themselves, lethal projectiles.The packaging is pretty bad, I only received a single set of blades; I think the others 2 pair must have fell out of the packaging and slipped through the box.

Can't tell you how many holes I have drilled with this in several different kinds of wood and it's still holding and edge. An arbor, three pilot bits and a hole saw that has already earned it's way for 10 bucks isn't bad.
