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 threaded hole for the center bit was tapped & crooked. My my corded DeWalt Drill 3/8 chuck wasnt big enough.

Ive only used it once. Well see how it holds up but for the price it served my needs. And beats having a repairman come out

Perfect

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.

It didnt cut my test piece of wood. Also didnt fit my corded drill, I had to borrow a cordless drill. Why the chuck was slightly bigger on the cordless drill than corded drill, I dont know.

Very happy with purchase. It saved a ton of time during the install of our basement lights. It was well worth the price when you factor in the time saved.

I have no complaints I used it to cut over a dozen hole in 1in thick hardwood for a project. Works great

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

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.

I got this to work but its a little smaller than 4 so I had to work it to enlarge the hole for my 4 dryer vent. This was pretty much a one time job so it worked OK.
