A favourite of CNC enthusiasts is to 3D carve and a ball nose router bit allows you to do just that. These are a great entry level bits as the are value for money compared to tapered ball nose. The radius = 1/2 of the diameter with no flat bottom. These bits can also be used to engrave lettering.
Suitable for
- Plastics (ABS, acrylic, HPDE etc.)
- Wood (MDF, hardwood)
- Wood (Ply & softwoods)
Adam’s Tips
Cutting against the grain reduces fuzzy material forming in your carve. This can be set in your 3D carving software under the term "raster".
Best for
- Budget 3D relief carving in hardwood, softwood, ply, MDF, acrylic, ABS and HDPE
- Finishing passes after roughing with a flat end mill
- Engraving lettering with a rounded groove
Not for
- Very fine detail: use the tapered ball nose
- Aluminium and steel: use the DLC, HRC45 or TiSiN ball nose
Adam's Tip
Choose the largest radius that still fits the finest detail in your model, since smaller radii need a smaller stepover and take longer. Cut across the grain in timber to reduce fuzz.

Great with ply!
Clean and accurate! Using this end mill will probably reduce my finishing time by about 90% and that's a conservative estimate!
