> 3 dayMade one hole through 5/4” decking spring came off and blade became extremely dull! If not for wood my mistake but it’s definitely a fight for the second hole!

> 3 dayThe pilot screw breaks easily. Was just trying to go into 4 PVC Schedule 40 and the bit breaks like nothing. Seems to be a good product, but the pilot drill bit is very flimsy. This is paperweight now until I can buy another pilot screw. Not strong at all.

08-06-2025Bought 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.

> 3 dayNeeded a hole saw to drill through 150 year old very thick plaster to install new can lights in the house were remodeling. Hole saw is heavy and very well put together. Cut right through the plaster and lath under it. Didnt dull at all. Would buy again if I need another one.

> 3 dayBought two, and both drill oversized. One drills 0.20 oversized and the second drills 0.30 oversized. If you are drilling say a bolt hole, it’s a really sloppy fit. The quality of build was fine, but the accuracy wasn’t.

> 3 dayI needed to cut a 3 inch hole into 10 gauge steel and this worked very well. I do wish the guide drill was attached a bit differently more firmly but it worked very well.

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 |
