Review on 🔩 Cobalt Hymnorq: Highly Resistant Stainless Steel by Kirt Phillips

These drill bits work great and are as advertised. If you are looking for larger diameter bits then I would recommend reading the product description before purchasing. I can only imagine the same people buying shoes. lol. I use these bits in my countersinks. flat surface on the shank of one of the interchangeable bits and insert it into the countersink. Clamp the hex head screw onto the flat of the shaft for a secure fit. I drill almost everything with these nozzles. They are fragile and will break if you are impatient and push too hard or drill too fast. you can do that to some extent with wood. but not metal. With proper use, these bits will pass and stay fairly sharp. On the plus side e, you get quite a few of these for a fairly low price, so it doesn't matter if you break a few. Imo all the cheaper m42 and m35 bits work just as well as the familiar overpriced brands. I don't spend any more money on it. They don't last longer than the cheaper ones and are made of the same material. 8% cobalt means the same no matter how much you charge per bit. Definitely buy these bits if they are the size you need. The really small 1mm will probably never see much use, but keep it with you just in case. Tip: Wrap 1mm tape around the shank to allow your chuck to hold them if they are too small to be gripped by the chuck or other tape. Duct tape also makes them easier to find when they're in a drill stack in a drill drawer (we all know that's where most bits are kept). !
