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

Threads on saw/bit failed on first use. Junk!

Value and precise size of finished hole.

Used it to make a feral cat house. Cut right through a double sided cooler & didn’t leave rough sides to the cut.

Not worth paying something that wont work. Blades are weak.

Worked as I expected and only 1/3 price as most at the hardware stores.

Needed to cut one hole in my soffit foot an exhaust fan. Did the job, though if I needed to cut more holes I’d buy something of better quality.

I needed to cut a perfect 4 inc hole hole in an acrylic panel for our bathroom shower system. This hole saw was perfect, most likely will only be used once but for the money it was perfect.

It comes with an arbor. I had only 2 holes to cut, and it handled the job fine. It was pretty cheap, and it would probably cut a lot more holes, if I needed them.

Cuts drywall without damaging wall finish Proper size for electrical box

I really cant complain, it made a 6 in hole as advertised. Its a cheap hole saw, if you only need to make a couple of holes this is the cockford ollie, if you need to have a 6 in hole saw for actual day in and out work, I would look elsewhere.
