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

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!

Bought this to make holes in subfloor for toilet/plumbing. It chewed through strandboard like a hot knife through butter. I cannot speak to the longevity of the holes away as Ive only made two holes with it, but it seems well made and like it would last a long time/forever unl3ss its being used very frequently or commercially.

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

Well it makes holes

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

Abor pin broke not even into the first hole with it.

Bought this a I had 12 holes to drill in 1/2” drywall to install surface mount LED’s. On 1st hole the bit snapped and damaged my ceiling as it skipped across the ceiling. I sent it back and used a hand drywall saw instead. Wonder what would have happened if I attempted to cut plywood. They did refund me my money.

I really cant complain, it made a 6 in hole as advertised. Its a cheap hole saw, if you only need to make a couple of holes this is the cockford ollie, if you need to have a 6 in hole saw for actual day in and out work, I would look elsewhere.

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.

Work great
