> 3 dayI read most of the reviews on this 2-1-2” hole saw and tried it anyways but bought two just in case. The first one went through no problem I was drilling through 1/2” steel plate kept the lube to it was patient and no issues. The only thing was the spring to push out the piece came off pretty much right away. Didn’t chip any teeth and worked fine. And some reviews said over sized but as you can see it wasn’t.

> 3 dayPilot 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 dayI used my 21mm hole saw to drill 16 holes through 3/4” thick steel plate. Eight were set up and drilled on a Bridgeport mill. Eight were drilled by a cordless drill in the field. I did not notice wear or loss of performance at 16 holes. The pilot bit overheated since it drills faster than the hole saw. For thicker material, I recommend through drilling a pilot hole the same diameter, so the pilot bit can act as a guide and not have to work so hard.

> 3 dayBroke the first pilot bit and order 5 more… didn’t break a second.. It did the job of cutting into my well casing…seems to be undamaged. It not a very easy hole to drill drilling into a non flat surface do yourself a favor and start on your lowest clutch setting or you will break the pilot.. It did have alittle wobble to it. But not to bad.

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.
