I drilled a hole in my workbench to find a grip. The drill bit cuts slowly and heats up quickly. I passed, but it took longer than I thought. The bank does not go into the hole. When I measured the "3/4" jack it was 20mm, but that's not the fault of the 3/4" bit.
I was just trying to drill a hole in a wooden floor without using a floor joist but the tip of the drill bit broke and it barely went through. Not a strong product for me. I mean I didn't expect him to run a marathon but the first and only hole was such a big fight. I think no. I would honestly like to return this product, it's useless to me, sorry.
My original shovel but it could go through one side of my wall but not the other side in a clean drill bit. With this I could make a hole right through a wall on the other side, so I didn't have to measure and guess the other side. This made drilling holes for cable routing much easier. The purchase was worth it!
