> 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.

Multi-tooth Alloy Cutter HeadThe cutter head adopts a multi-tooth combination design, which is composed of three groups of cutting edges, inner, middle and outer, so that each tooth can be easily stressed during the cutting process, making the cutting smoother and faster. |
Carbide TechnologyTough Tungsten Carbide teeth extend past inside and outside walls for reduced friction and much faster cutting.
|
Stepped Pilot Drill Bit DesignProtect carbide teeth from impacting when the pilot drill bit through the cutting material，Eject the slugs easily, reduce the chip-blocking problem because of the spring design |
Warm Tips:
- Please insert the flat end of the pilot drill bit into the hole of the hole saw and lock it with a screw to effectively prevent the pilot drill bit from shifting, breaking and other problems and prolong the lifetime.
- This Hole Saw cannot be used for Concrete,tiles and stone.
- Do not forget to ues a lubricant so that the bit does not overheat.
