4-1/4" Carbide Tipped Hole Saw for 4 Inch Recessed Lights and Dryer Vent, 4.25 Inch Hole Saws Cutting Hardwood, Drywall, Plaster, Ceiling Sheetrock, Fiberglass, 5X Faster, Green

This is a great carbide hole saw at a very low price. I purchased the 4-1/4" size hole saw to cut a hole in a stucco covered garage wall in order to install a dryer vent for my laser engraver's exhaust system. This hole saw cut through 3/4" of concrete stucco, steel wire lathing, felt paper, 1" of Styrofoam, 1/2" of OSB, 3-1/2" of fiberglass insulation, and 3/4" of sheetrock like a hot knife through butter (using an 18v Bauer cordless 1/2" drill). There was no damage to the hole saw at all, except for some of the bright green paint being scuffed. The carbide tips are still in like-new condition.This carbide hole saw actually works very well, and it is a bargain compared to the same size name brand hole saws sold in the big box stores for two or three times the price of this hole saw. I highly recommend this hole saw to anyone that needs to cut through some tough materials, although it cuts through regular wood very well also.

durable, ease of cutting use works perfect for the old mixed ceiling material

I previously purchased one of these hole saws (slightly smaller diameter). I liked it so much that I didn't even shop around before purchasing this brand... I just selected the proper size and clicked "buy now". The saw is very heavy-duty/durable, and the cutting teeth have been making short work of wood and composite siding. I highly recommend!

Old plaster wore the teeth of A normal hole saw after one hole. This one is on 10 with no signs of slowing.

I wanted to drill a hole through the side of my garage for a dryer vent but did not want to spend $60 on the bit, so here I am. Went through stucco pretty easily and left a clean home. Did the job.

I used it to cut three holes for recessed lighting so far. Two through plaster/lathe and another through some kind of hard stucco like ceiling. Did a nice job on all three. Highly recommend a dust bowl such as the one from Disston to keep the dust under control.

These drill bits make my job easy.

Worked like a charm. Nice, clean cut. Properly sized hole for my 4" recessed lighting.Side note: The included mandrel will work for other hole saw sizes from other brands.Bottom line: Good hole saw at a good price.
