4 flute end mills are a stable, strong general purpose tool used for slotting, profiling, and contouring in stronger materials where chip loads are less and your end result needs a great finish.
We designed a fabulous 4 flute solid carbide end mill and then took care to make sure our customers have it in the combinations of styles, sizes and lengths they need and then offered it at a price they could afford in our Design-Rite line. However, that didn't seem enough. So, we took it one step further and created it in a variable helix version. But we didn't stop there. We added a version with chip breakers so you move faster and remove more metal without jamming up the flutes. The Design-Rite 4 flute carbide end mill, it's everything you expect in a 4 flute end mill and more.
