I bought 8 LED recessed can light fixtures to upgrade the lighting in my kitchen. These required 3-7/8" holes to be drilled in the ceiling sheetrock. This hole saw was the exact diameter. The only reason I give it 4 and not 5 stars is the fact that neither Amazon nor the supplier highlighted the fact that it requires a 5/8''-18 hole saw arbor instead of the more common hole saw mandrel. This caused some inconvenience and delay. I eventually bought a hole saw arbor from the local store for 4 times the price of the hole saw. If Amazon and the supplier are listening, may I suggest that you (1) highlight the fact that this hole saw requires a 5/8-18 arbor and (2) recommend the matching arbor along with this product as well.
However, the saw did not cut nearly as well as the ones in my Milwaukee brand set. There seemed to either be too much paint on it, or the teeth were maybe not offset enough. Anyway, the saw "loaded up", and overheated. It was barely deep enough to bore through the end joist on my old farmhouse (dimension lumber), even after I re-bored for the mandrel.
Even though this saw did manage to finish the job, I'm glad I didn't buy a whole set of this brand.
MK Morse M45P 7/16-Inch Arbor unit, was a better deal than I could find on the web, or in the big-box home stores. Once you get up into this larger size range, the blades & arbors are sold separately, for big bucks.
I needed to drill a clean, neat 3.5" hole (exterior wall) into the vinyl siding, thru the foam insulation, old shingles, old fiber insulation and the 1/2" wood, for a 3" PVC sch40 pipe(3.5" OD).
I figured going 1/8" larger than I needed would make installing the PVC easier.
It was actually too easy. It was a little loose. I probably should have ordered the 3-1/2" saw.
Anyways, this saw is very sharp. The hole in the vinyl siding is perfect. No chatter marks at all.
As it passed each layer, I pulled it out and cleaned out the center, using a nail
in the side slots (clean-out slots). Having used other brand hole saws before,
when installing mini-splits, I was surprised at how quickly and cleanly this Morse AV58 cut.
The threaded hole for assembling the saw blade and Arbor (MK Morse M45P 7/16-Inch Hole Saw Arbor) was perfect. When tightened up very snugly, the Arbor's pins were exactly alined with the holes. No wobbliness in this tool. The drill was an Hitachi FDV 16VB2 1/2".
This is the perfect hole saw.. Too bad I only needed one hole! :(
