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

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!

Works as expected, great value for the money.

worked well on my aluminum boat. Used with a hand drill.

I used this hole saw to install an electrical box in a plaster wall with 2 X 6 lumber behind. It bored through the plaster and wood with ease.

Worked perfect , spring came off but still worked perfect

Pretty good quality

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.

Product was not square, causing it wobble.

Very durable! I looked at other hole saw kits with shallower depths for same price, but a variety of saw sizes including case. Needed it for sheetrock. Glad I went with more expensive singular piece! Still one of the cheapest as individual 4” hole saw. Gets the job done. Worked well with my hammer drill!
