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

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.

Well it makes holes

Product needed a half inch drill, I only have a 3/8 drill. Bit was not fastened to hole saw and came loose every time I tried to use it. Could not be tightened any tighter.

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.

Used it to cut some holes for downlights. Worked well.
