AUTOTOOLHOME 5.1cm 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.

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.

Worked better than expected for the price

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

Cut the 2 inch hole like butter. Several short bursts with the drill not to over heat the stainless steel and harden it. Cut hole in about 2 minutes. Would buy again!
