4-1/8 Inch Carbide Grit Hole Saw for 4 Inch Recessed Lights, Dryer Vent Hole, Cutting Through Stucco, Ceiling Old Plaster, Drywall, Cement Board with 1-1/2" Depth, Up to 6X Faster

I have a 100 year old stucco home and this bad boy drilled several holes in the facade allowing me to vent a few bath fans and a dryer. I also used it in lathe/plaster for a few kitchen can lights. Highly recommend for dilling through stucco facades and lathe/plaster.

It cut through 1 1/2" stucco wall nice and easy and is still in Great conditionI then cut through some drywallnails and all no problem my dryer vent is now installed!

works great

This bit was a waste of money. I made it about ¼" through the stucco and it was shot. ZERO STARS is the actual rating. Do not waste your money on this, I honestly knew before I bought it but I thought I would get the 1 hole I needed but I didn't even get half way through ⅞ stucco.

The cutting edge works, but the chuck has weak pins that deformed after one job. Don’t buy if you want a heavy duty coupler.

Did what I needed to do, had to cut a few chores in hardie board and trim, went thru cementious fiber siding with ease

I was concerned about quality at this price point but figured I'd give it a try. We're using it for hardie board siding and so far have gotten around 15 or so holes out of it and still in good shape. (Compared to a Milwaukee bi-metal getting one hole in Fibre cement without burning up if your lucky) I would highly recommend for Fibre cement does not cut wood that well but will if you really need it to.

It works for about 20 holes in the toughest material. Buy them by the dozen. Worth it, amazing while still sharp. If just drywall probably last till you loose it.
