Review on Tungsten Carbide Engraving Drilling 0 25Mm 5 5Mm by Doug Hook

I really thought I could use these little things with aluminum. I broke almost all of them on the first night. Some of the larger ones cut through aluminum well. That CAN work. But if you want to work on the details below, maybe 5mm, they all break. I think for softer materials or large roughing of aluminum they are fine. Not suitable for small parts on aluminium.
