Decent end mills for soft materials NOT for aluminum.
Lane Waddell✓ Verified Purchase•September 28, 2023
I really thought I could use these little guys with aluminum. I broke almost all of them on the first night. Some of the larger ones do a good just cutting through aluminum. It CAN work. But if you want to do any detail work below maybe 5 mm they all seem to break. I think for softer materials or larger coarse work on aluminum these would do fine. Not good for fine details on aluminum.
Ok
