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

Made the cornhole without any issues or splinters

Small length. !

Couldnt even get through 1 piece of 20 gauge sheet metal.

Not the highest quality, looked like it may be a second. But it worked good to cut the holes in 1/2 in plywood.

Value and precise size of finished hole.

Seemed like a great bit for the price, but is starting to dull after drilling only7 holes in drywall, i would guess it would be just as dull after 1 sheet of 3/4 plywood. But you get what you pay for. It should work to finish this project since im only drilling drywall, then it will be tossed.

wouldnt cut through a thin sheet of metal

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.

I needed this hole saw for an at home DIY project and it met my needs with no problems. Having sold/used commercial brand hole saws in my prior life I can tell you this saw and arbor are not the same quality as the red box or blue/white box products, but you are also talking a fraction of the price. Overall I am happy with this product. It fit my needs for a one time DIY project at a very affordable price & I would recommend it to a friend with similar needs.
