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

I purchased this saw for my outdoor recessed lighting project and the saw would not cut through my soffit. Had to use additional saws and drills. Complete waste of money and time.

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!

This saw and arbor feel solid and looks like it’s a good price/quality ratio.

Did the job

not so great for stainless steel

Bought this to drill holes for corn hole boards I make. Works decent for this task, but I would use it on metal. The spring on the drill is a bit odd and I am not really crazy about it... I honestly dont think it will last so not too worried about it. I am also not too crazy about how the drill holder mounts to the saw portion. The quality of the saw seems good and will last for my needs. Overall, for the price and how I use this, it works fine and I happy with my purchase.

Mandrel stripped out immediately! This is junk!

Does the jobs but you may need 2. I did 6 holes in plaster ceiling.

Broke on first use , not much else to say

A bit heavier than anticipated, but this leads to longevity. It did the job well.
