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

Just an fyi need a 1/2 chuck to get this to work. 12v tools dont fit.

The center bit broke in half on the outer wall. The teeth were not sharp at all. Its buy point is cheap for a reason.

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!

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

Well it makes holes

Used it to cut some holes for downlights. Worked well.

It took me very long time to cut the ply wood. I am not sure whether they designed in that way or it should be sharper. But cost wise, I cant complain.

arbor threading was not tapped square. so when drilling the whole saw wobbles and is unusable. horrible construction

Item came with wrong arbor. The thread size of the arbor was not the same as the thread size of the hole saw.

wouldnt cut through a thin sheet of metal
