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 it to cut a hole in my living room cieling to install a cieling fan. Home Depot has one for $38. This one was only $13 & I might never use it again. So...

Both drill bits supplied snapped immediately only drilling through drywall. Hole saw itself does work decent, but kit is cheap.

Only used it a few times but it held up well

Don’t understand the negative reviews??? It’s a cheap hole saw that does what it’s supposed to do… I’ve cut 12 perfect 4” holes for gang boxes and the last hole was as good as the first . Some were in sheet rock some were in 3/8” beadboard, all clean and perfect! And I paid less than $15.

I used it to cut drywall for recessed LED lighting.

Too small for whole saw!! Please help

The yellow hole saw stripped in the mandrel in the first day of using. Metal too thin. Of no use to me after a hole or two cut.

Not worth paying something that wont work. Blades are weak.

Bit was unusable because bit lock was missing which made it unstable and dangerous.

If u plan on using this buy a different arbor. First use the arbor strips the threading. U need a arbor that has the 2 prongs poking into the saw. If u don’t, to much force and its game over. It’s almost worth just buying a saw that comes with the better arbor. Even going slow on drywall the thread will strip. I used mine for a hole for a dryer vent and I couldn’t even make it past the drywall.
