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 aluminium or brass and much more.
Suitable for
- Plastics (ABS, acrylic, HPDE etc.)
- Wood
- Steel
- Soft Metals (use an appropriate coolant)
- Ferrous metals (use an appropriate lubricant)
Adam’s Tips
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.

2 flute tapered ball mill for 3D carving
Really impressed with this bit, I was doing a 3D carve with this bit after doing a roughing pass. Even in areas where the roughing pass was imperfect and left too much stock this bit had no problem chewing through some rather hard african mahogany offcut I was using, even down to the 0.5mm nose. Good surface finish too. Would buy again.

2 FLUTE TAPERED BALL NOSE
Works very well for me. It has the stiffness and reach to be able to cut the really deep detail.

2F Tapered Ballnose
Recently purchased a few TBN cutters from .5 to 2mm tip. Tonight I used one with a 1.5mm tip to do a 3d carve, it worked quite nicely. I have purchased these from Adam's Bits and like all his other cutters I find it hard to find any difference in quality than more expensive brands. I use the TBN mainly because I can often go straight to a finish pass without roughing, which is possible if one uses a raster toolpath. But it depends on the design.

0.25mm tapered ball mill
I carve some insane detailed STL files with this, it works absolutely awesome! If you carve 3D reliefs then I honesty can’t recommend a better bit!
