Mine actually might be a touch smaller than 6 inches in diameter. If youre thinking of using this to cut recessed lighting can holes, like I did, you will have to ream them out after you cut, like I did.. Other makers make the saw slightly bigger than 6 inches. This one is small than 6 inches. Gave it 3 stars because it was not expensive.

Tends to lock up a bit and the drill will detach unless you really tighten it. Overall got the job done.

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.

the threads spun out of saw first use. I used the included arbor and it stripped the threads out of the saw on the first use. Most arbors for hole saws of this sixe use a arbor with pins to keep the blade from twisting on the threads but this one did not, so get what you pay for I guess.

Worked wonderfully and I was able to do myself with ease

Solid holesaw for cutting 4 inch holes.

This saw is not 4 inches in diameter. I needed it to be at least that. Waste of time. I returned it.

Missing the arbor

Did the job

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.
