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.

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!

Tapered Ball Nose Mill review
Excellent, sharp and strong bits. These bits are great for carving out details (used in hardwood) and produce a reliable and clean finish.

Tapered bit
Bought to do 3D carve, bought a 6mm shank to push the machine a bit faster and reduce flex at the point of carve especially at end grain points. Wasn't disappointed and an excellent finish.

0.25mm Tapered Bit
I have done some very fine detail 3D/STL carves with this bit, the carves were in very old and dry, easy to splinter Douglas Fir and this bit handled it flawlessly without a single splintering. The detail was epic! Highly recommended!

Excellent value
These bits work long and hard yet hold a sharp edge month after month

Ball nose Bits
I have only recently tried Ball nose bits, I wanted a really small tip that wasn't as fragile as a 1/16 or 1/32 so I got the R0.25 & R0.75 and they work a treat, and didn't break :)
