The most versatile bit you need to have in your set is the tapered ball nose. Capable of engraving wood, plastics, soft metals and even steel, these are a high quality bit and withstand a beating even with a R0.25mm tip. Some uses of this bit include cutting PCB tracks, engraving lettering in ABS or even steel plates, 3D carving of aluminum or brass and much more.
- Plastics (ABS, acrylic, HPDE etc.)
- Soft Metals (use an appropriate coolant)
- Ferrous metals (use an appropriate lubricant)
Avoid a deep depth of cut to improve the finish of your material and increase the feed rate to make up for lost time. Also, use a coolant when cutting soft metals and lubricant when cutting ferrous metals to ensure the cleanest finish.
