> 3 dayI bought this for sheet metal. It worked pretty well. I did have to go in reverse to get a groove going and go slow so I didnt rip the metal. Lowest priced one I could find.

> 3 dayUsed on my drill press to cut 3/16 steel plate . My experience with normal hole saws has not been good , but this hole saw cut thru the material with no damage to the tool. Starting another cut soon - but pretty sure it will handle it . Next hole saw I buy for metal will definitely be Mollom !

Greater than one weekCut through a 8n tractor dash with ease for a two inch voltage gauge. Go slow with slight pressure, or you might break your wrist. The cutting took about fifteen minutes with cutting oil. I would recommend this product.

Greater than one weekOwned this 1” (25 mm) hole saw for all of 14 hours, the carbide teeth lasted about 2 minutes while drilling low carbon mild steel. I bought this bit hoping to drill 6 super smooth holes in 1/4” mild steel as I had purchased a smaller 3/4” bit from another source that worked great in the same material and much harder material. All the teeth on this bit broke off with only 60 percent of the first hole cut. Bit is Completely unusable now check the photo. For reference, I finished cutting the first hole with a regular bi-metal hole saw that was countless years old and literally missing 3 teeth. I then cut the remaining 5 holes with the bi metal blade so it wasn’t because the steel was too hard.
