Review on 🔧 Enhanced Woodworking Efficiency: Adjustable Countersink Collars for Precise Counterboring by John Rocha

I bought these bits for a small woodworking project. They arrived very matt and burned/smoked the wood when I first used them. The sink works well but the base part is terrible. I haven't tried the setting because I don't need it for my project, but thought it would be a nice feature.
