Greater than one weekPilot bit broke on first hole, replaced pilot with a Milwaukee bit and kept going. Before the first hole was finished all the cutting teeth broke off on 1/8 steel sheet. Do not recommend if I could go zero stars I would.

> 3 dayAs the title states, the feeder bit broke on the very 1st hole. It was only a typical metal stud and nothing thick at all. It broke immediately as it penetrated. Im a plumber and tend to use a hole saw for my holes but after trying out a similar kit to what this bit is, figured it would work great. It didnt work at all. Returning for refund and I will not bother to try again. Time is money and this feeder bit (also called the guide bit) is far to cheap to work as such a bit would require.

Greater than one weekBought the 180mm (7.x) hole saw to drill a hole in a 250 gal propane tank, my smoker project. It cut it, still has its teeth and I presume would be able to cut more. I figured it was a 1 and done use but if I ever need to use it again it might have some life left in it. Worked out perfectly for the 7 pipe Im using for the stack.

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.
