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 came with the threaded hole way off and stripped out before the first hole was complete.

Too small for whole saw!! Please help

Well made and the bi-metal is a plus. Good price. Fast delivery. I used it to install small canless LED lights where you want a nice clean cut to support the fixture. It has the side slots so that you can line it up on a mark easier. The bit is well anchored and comes with small Allen key wrench. The housing is nice a deep and thicker than hole saws that are cheaply made.

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

Value and precise size of finished hole.

Very nice for the price and worked for my cornhole boards.

Threads on saw/bit failed on first use. Junk!

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.

Threads ripped out halfway through second hole.
