Review on Tungsten Carbide Titanium 💎 Plated Plastic - ASNOMY Enhanced by John Floyd

I managed to drill 6 holes in the aluminum body then I drilled a few holes in the stainless steel of my cab panels and both pilot drill bits broke and wore out. Carbide eyelets before I could drill 2 holes in them. I had to order another one to finish the job. It worked but there is no durability. These are single hole drills and that's it. Update: The seller quickly contacted me and sent me two more. I must have a bad batch. Can't say anything but great customer service and they really stand behind their product!
