ASNOMY12PCS TCT Hole Saw Kit for Hard Metal, 5/8"-2-1/8" Inch Tungsten Carbide Tipped Hole Cutter Set with Titanium-Plated Pilot Drill bit for Metal, Stainless Steel, Iron, Wood, Plastic

We have used several sizes of these bits and they cut through steel nicely. I'm satisfied with this purchase.

These bits are very sharp and good qualityI bought a mag base drill to use for these bits. I had a few small bits, and it is not good to try to use bits on metal with a regular drill. I tried that months back and you cannot hold it steady and straight. Or at least I could not hold it straight after just a little bit into the metal. It twisted and grab a good bite and broke the bit. Thank goodness I have learned a valuable lesson. I usually have to pay for my lessons leaned. I really wish they would put there rpm list of different materials to drill. It really makes things a lot safer and major difference when cutting carbon verses stainless . That’s all I got to say about that

I have used these bits a few times now and they BITE! I have had no issues so far with them cutting. They are sharp and accurate. I used these to cut out slam locks in aluminum. I have not noticed any teeth breaking off during my use so far. It cuts through metal like butter. I recommend this product for those looking for a good metal hole saw.Update: Upon using the 1-1/8 hole saw for the first time, the shaft shattered within a few seconds of drilling into 1/8 aluminum sheet metal. Luckily, this set comes with two extra shafts so I was able to replace the shaft and finish drilling the hole. This was a little disappointing as I had no issues when using the 2" hole saw. Time will tell on how long these will last.

I’ve used the 1/2 & 7/8 several times now and they really performed well on 1/4” thick steel
