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

Used for installing a kitchen hood unit air exhaust in side of house. Only used once. Did the job well. Nice clean cut. Perfect 6” hole. Can’t attest to longevity as this was a one and done use for me. But based on my experience, I would recommend!

I drilled over 200 holes in drywall and I occasionally hit a nail or wood and the teeth on the bit stayed in tact. I use this to install recess lighting. Great bit

Adequate for my limited use boring thru fiberglass bulkheads for installing vents.

Did the job

Did exactly what I bought it for, drill 6 whole in 1/2 plywood. Locked in place, as some others do not as I read in reviews of other products.

Works great for ceiling lights

Does what it is supposed to do. Very good price.

Used to cut holes in drywall for ceiling fan boxes. This hole saw worked great! I would purchase again. There is a bit of a learning curve when using this type of hole saw for the first time. Practice on same type of scrap material.

Very nice for the price and worked for my cornhole boards.

Used it to cut a hole in my living room cieling to install a cieling fan. Home Depot has one for $38. This one was only $13 & I might never use it again. So...
