Review on 🔪 Precision Carbide Engraving Milling Machine by Uxcell: Uncompromising Quality for Impeccable Results by John Larsen

I like these bits but don't use them on CNC machines. I use them to drill very small holes in seashells for crafts and jewelry making. They drill and cut very well and will not split shells like a normal twist drill. It also cuts sideways, which is very useful when cutting small parts. After the first order I ordered 3 more packs. The bits don't last long and dull quickly, which is their only downside. I am very satisfied and will order more in the future.
