AUTOTOOLHOME 2 inch (50mm) Metal Steel Hole Saw Tooth Carbide Tip TCT Drill Bits Kit for Thick Metal Wood

The "AUTOTOOLHOME 2 inch (50mm)" is a very good hole saw. I paid about $10 in April 2025 for this tool. I used it to cut 2" holes in 50 year old automotive sheet metal, and it performed very well. My old cordless drill could not keep up, so I switched to a reliable, powerful corded drill to do the work. The hole saw quickly started cutting through the steel, throwing off fine metal chips. I did not get the feeling that the cutter overheated or lost its cutting ability during the cuts. However I took the time to get even, consistent cuts, trying to hold the drill at a consistent position to ensure that the metal would cut through evenly. I let the tool do the work, and did not rush the job, however I don't feel like it took the saw an unreasonable amount of time to to make the cuts. For this project I only made 2 holes, so there was not a great amount of time to wear out the saw. During use I did *not* notice any broken or lost teeth on the saw after use. For the price, this cost me $5 per hole which is fair. I believe this will serve me well in the future next time I need it.

Worked better than expected for the price

Cut 6 2” holes in 3/8” hot rolled steel and still able to cut more. Expected/planned on getting 2-3 holes. No lost teeth. Cut slow using hand drill, about 100 rpm, and used oil frequently.

Hole saw worked great. Cut easily thru sheet metal. The bit broke after a couple of uses. Had to order another bit.

Amazing cut through metal and wood easy for me to install an water proof outlet

Needed to cut eight 2" holes in cold rolled mild 1/8" (11 gauge) steel. Very pleased that I was able to cut all the holes w/o too much difficulty using a $10 hole saw. After the eight holes, saw teeth were still intact and seemed sharp with no noted distress. Obviously not for commercial use but great if only need to cut a few holes. Caveats: - The provided drill bit was totally worthless being extremely dull, not sure it would drill thru soft wood. Not a big deal, I used my own bit to drill thru the 1/8" steel and used the saw bit as a pilot. - Worked best with a corded drill, moderate pressure at moderate speeds using oil. - Did not work in a drill press, assuming the drill attachment was not aligned with the saw; so hand held drill worked best. - Teeth are fairly thick so you do remove a lot of material.

Description claimed it cuts wood as well as metal. No it doesn't. cuts about 1/16" then the teeth clog and it stops cutting. Don't waste your money if you're trying to cut a hole in wood, use a standard hole saw. Maybe it would work better on metal.

Well built core drill. Very slight wobble (run out) noticeable at slow speeds. Wide teeth make it very time consuming to cut aluminum plate (3/8" thick), but makes a very clean hole. Teeth clog up easily and need to be cleaned all the time. Take your time and it will work.
