JIECHENG Bi-Metal 4 inch Hole Saw with Arbor Mandrel for Cutting Wood,Cornhole Boards,Drywall,Plasterboard,Plywood,Steel,Aluminium,Brass,Copper,Zinc,Tin,102mm

Exceeded my expectations despite the very inexpensive cost! After drilling 15 holes through plaster and plaster board, the blade is still sharp. I just needed it to last long enough for this one project, but looks like I can keep it in the toolbox for future.

I used this hole saw to install an electrical box in a plaster wall with 2 X 6 lumber behind. It bored through the plaster and wood with ease.

My husband says he LOVES this thing. Find the center. Drill the hole. Drop them in! Easy peasy! We just put in about a dozen lights in our basement. So simple and they look so good! This is what you need to make it a smooth process!

Cheaper than others name brands and gets the job done, we shall see if it keeps cutting.

Lasted about 5 minutes

Very satisfied. It cut through my metal garage door to install a vent. Took about a minute.

Cant really speak to longevity; I needed to make a half dozen holes in plasterboard for some ceiling lighting. This was the cheapest 6 inch hole saw I could find, and it worked perfectly for the task.

This is a decent, cheap hole saw that gets the job done. I used it to cut holes in ceiling drywall to install remodel 6” recessed can lights. Unfortunately, this saw measures slightly under 6”, so the resulting holes were not large enough to fit the cans. I had to enlarge them a bit with a drywall saw, which then defeated the purpose of using a hole saw to make clean cuts and minimize dust in the first place. Also doesn’t last very long… it was adequate for what I needed without breaking the bank, but you get what you pay for.

Worked as expected. Cutting out a vent hole and hit a bunch of nails and it didnt harm the blade at all. Definitely worth money.

Great price and very good quality. Cuts rapidly through 3/4 material. With proper care should last a long time.
