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

The middle drill bore was skewed by 10 deg. Those are factory rejects.

Did exactly what it was supposed to do and was easy to use. Core came out easy and stayed sharp after several hours of use. Good job

Broken part

Product was not square, causing it wobble.

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.

Was only sharp to drill hole for one hole in pine. Second hole wouldnt cut.

worked flawless for job .

I was gonna return this and vent a different direction where I could cut the hole through a single piece of wood. I thought I could use my jigsaw. Changed my mind again and opened the box and found nothing to secure the drill piece to the saw piece . Just the bit saw and hex wrench. totally unsafe and wouldnt work. Thank you Amazon for free returns!

Center drill broke immediately upon use. Good thing I had spare center drill from a Milwaukee smaller hole saw kit.

This worked perfectly for cutting the holes in the cornhole games I built. I definitely recommend this product.
