Genmitsu TB04A tapered ball nose end mill set, 1/8 inch shank, 4 pieces
Genmitsu TB04A tapered ball nose end mill set, 1/8 inch shank, 4 pieces
- Tapered ball nose bits carve smooth 3D shapes and fine detail in wood.
- The 1/8 inch shank fits the bit clamp on small hobby machines like the 3018.
- The set has 4 tip sizes, from very fine to medium, so 1 box covers most carving jobs.
Also fine: CMT 3D tapered ball nose CNC bit, 1/4 inch shank if your machine takes 1/4 inch bits and you want 1 top-grade carving bit.
The unpaid alternative
Use the bits that came with your machine first. Many hobby CNC kits include a few. Do a test carve in scrap pine to learn what you really need.
No commission on this line. It stays on every verdict.
How we decided
We matched bit shapes to wood carving and bit sizes to the clamps on hobby CNC machines. We chose a small carving set over big packs of tiny bits. On 13 November 2026 we checked the Genmitsu TB04A set on the maker's own page and found it on sale at Umart for $31. We checked the CMT tapered ball nose CNC bit at Carbatec. No sale date changes this advice, because bits are low-cost parts you replace as they wear.
In Australian shops: $30 to $40 when we checked. This is not Amazon's price. Prices move, so check before you buy.
