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

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

I disliked the fact that it took so long (>5 min) to even score the plywood! Not my 1st time using a hole saw either! Later cutting with a different brand hole saw, took about 20-30 seconds. it was as if the teeth were dull altho they felt sharp. Kinda like you were running the drill backwards!

It broke on the first use didn’t even make it all the way threw before the holesaw threads striped from the bit

Great little hole saw for light fixtures - don’t get this if your doing a dryer vent as the vent is a little bigger than 4inches ( I had to test all the ways I could use this )

Works pretty well. Not extremely sharp but has large enough teeth that the average person can sharpen them with a small file if need be. It’s quite well-built and has worked well on a dozen holes for me and plywood and sheet rock.

Worked as expected. Cutting out a vent hole and hit a bunch of nails and it didnt harm the blade at all. Definitely worth money.

A bit heavier than anticipated, but this leads to longevity. It did the job well.

Very dull. Threads need to be reversed so the arbor doesnt go spinning off. Just made it through 1 hole in 1 press board. Would buy again.

Value and precise size of finished hole.
