Review on 🔧 Efficient Performance: SpeTool 3 Flute Carbide Cutting Machine by Paul Wilson

I've just started using my SainSmart desktop CNC but needed an upcut end mill for an aluminum project. These end mills did a great job on my project. The desktop CNC design is a bit lacking, so I can only cut 0.005 deep per pass. I ran one of these end mills for about 100 hours and there was no real change in cut quality. I broke an end mill when a part came loose while cutting, but that was my own fault for not setting my material properly.
