Liked it, drilling a hole

I used this hole saw to install an electrical box in a plaster wall with 2 X 6 lumber behind. It bored through the plaster and wood with ease.

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!

Lasted about 5 minutes

Very satisfied. It cut through my metal garage door to install a vent. Took about a minute.

Works great, good value for your money!

The bit did not fit my Makita FD05 3/8 drill.

Used for installing a kitchen hood unit air exhaust in side of house. Only used once. Did the job well. Nice clean cut. Perfect 6” hole. Can’t attest to longevity as this was a one and done use for me. But based on my experience, I would recommend!

Does the jobs but you may need 2. I did 6 holes in plaster ceiling.

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