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

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

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.

Worked wonderfully and I was able to do myself with ease

This is a bad and cheap tools after opening for light in the ceiling it’s was no good I have to go to Home Depot to buy a good one just got yesterday day u shouldn’t sell this item no more

The arbor doesnt come close to fitting the hole saw. None of the arbors I already have fit it either.

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

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 had to drill 10 holes in a ceiling for some recessed lights. By the time I was done with the last hole, it was so dull I wasnt sure it was going to be able to get through. If its supposed to handle the metal they say it can it should still be good for many projects to come. Anyone see any teeth there?

The arbor is too small to fit.

This saw chewed thru my aluminum truck bed with no problem at all. Worked great for putting in a gooseneck hitch.
