Review on Lenox Tools 30862638RL Recessed Lighting by John Rivera

Easily cuts through 1 1/2 inch thick plaster. Used this to cut tall hats in a thick plaster ceiling after going through many other hole saws. Super smooth. The edges of the plaster are not chipped or anything like that. I've cut 10 holes so far and it still cuts smoothly. Hope it lasts a lot longer.
