Amazon Milling Bit Holders—A Total Letdown! (And Why I’m Making My Own)

I ordered a pair of milling bit holders from Amazon, hoping for a quick fix for my tool setup—but what arrived was a complete mismatch. Every hole was oversized, the build feels like cheap 3D-printed PLA, and honestly, returning them isn’t worth the trouble. So instead, I’m making my own custom milling bit holder. Sometimes, DIY really is the better way.

If you’ve ever bought tools online and ended up disappointed, you’ll relate to this one.
