Review on Efficient Woodworking Drilling Countersink L Wrench with Automatic Cutting Tools by Bryan Hill

I ordered a set for the authenticity of the bits, realizing they probably won't last the longest, but I only need them occasionally. My fault for not reading more reviews. My biggest problem with them is that the collars keep coming loose. I mixed up two projects because the collars came apart. it doesn't seem to matter how tight you tighten them. I plan on grinding a flat spot on the bit. This should solve this problem, but I don't need to change the tools to get them working out of the box. They come in a grease-covered pouch. When you work with sharp-edged tools, you usually want to protect them. I was very surprised by the packaging. Not a fan of thick sticky fat either. It took quite a while to clear all the bits to make them usable.
