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

Didnt use this item, as the arbor is way off and would have resulted in a very messy and oversized cut.

Works

Great price and very good quality. Cuts rapidly through 3/4 material. With proper care should last a long time.

This would not cut through 1/2 plywood. Dont buy this

Used it to make a feral cat house. Cut right through a double sided cooler & didn’t leave rough sides to the cut.

The arbor is too small to fit.

Works great for ceiling lights

Worked as I expected and only 1/3 price as most at the hardware stores.

GOOD FOR 2 HOLES - IF YOUR LUCKY AND CONTROL THE SPEED - SLOW...

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.
