Greater than one weekI was skeptical about these by how cheap they are, but it works great. I even decided to buy the 5 pack afterwards.

> 3 dayOwned 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.

> 3 dayI used this hole saw to drill 2 in dia holes in 10 ga cold roll sheet. Having read the reviews, I understood that the pilot bit was crap, so I drilled a 1/4 inch pilot (much easier to do this prior to using a hole saw anyway). I used the bit in my radial arm drill press with cutting fluid and it cut much better than the typical bandsaw type hole saws. The saw cut evenly and consistently, resulting in holes that measured 2.030 dia. Im happy, so I ordered another one, just in case, as I make quite a few of these pieces. Shipping was quick.

Greater than one weekI used this 13/16” hole saw to drill (22) holes through 1/2” steel plates and structural beams. It worked flawlessly, and so much faster than conventional hole saws. I used one bit for these (22) holes and it still looks good. I kept it cool by continually spraying WD-40 on it and not forcing the bit through the metal. Take your time, run the bit at a low speed, keep cleaning the chips out of the hole, keep the bit cool, and let the bit do the work; you will be very satisfied.

> 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 dayEDIT: After using a better drill bit and Blue Loctite on set screw,, the hole saw worked fine. Bumped it up to 3 stars and overall, disappointed but made it work. Drill bit did not center properly and even broke on a test piece. Will update after I use a different bit and am able to complete an actual cut. This is currently being used on aluminum, 1/2 thick.
