Jewelry work lives or dies on the bit. A desktop CNC or a rotary tool can cut fine detail in metal or PCB blanks, but only with micro bits made for the job, and the best cnc bits for jewelry under 15 are all small carbide drill sets. This guide compares four bit sets on diameter range, material, flute count and pack size, so you can drill clean holes and engrave fine lines without snapping bits.

What the bit listings tell you
We read four micro bit listings for this guide. Diameter ranges run from single 0.7mm and 0.8mm sizes to 0.3mm to 1.2mm ten-size sets. All four state carbide in the title or bullets, though one spec table says high speed steel instead. Pack sizes are 10 or 50 pieces, and flute counts are 2 or 3. No listing states a warranty term, so all four score zero on warranty.
Buying guide: the best cnc bits for jewelry under 15
Diameter range
Single-size sets suit one repeated hole: the uxcell sets come in 0.7mm and 0.8mm. The 50-piece sets span 0.3mm to 1.2mm across ten sizes, five pieces each, which covers drilling, engraving and fitting checks in one box. Buy the range if you work many designs, the single size if you drill one hole size all day.
Carbide material
All four listings state carbide in the title or bullets: tungsten carbide on the uxcell sets, cemented carbide on the ApplianPar, tungsten steel carbide on the Sunxeke. One spec table, on the uxcell 0.8mm, says high speed steel instead; per the site rules the title and bullets win, so we score it as carbide.
Flutes and cutting angle
Three sets state 2 spiral flutes; the ApplianPar states 3 flutes with a 118 degree cutting angle. The uxcell listings state the spiral flute gives a sharper cutting edge that reduces cutting force, which matters because micro bits snap under side load.
Shank and tool fit
Both uxcell sets state a 3mm shank, about 1/8 in, which fits common rotary tools and CNC spindles with a 1/8 in collet. The ApplianPar names Dremel in its title. Check your collet size before ordering; a bit that does not fit the collet is a paperweight. Also see our best cnc bit set for engraving for larger engraving bits.
Pack size and value
The 50-piece sets give the most range per box, while the 10-piece uxcell sets give one size with fully stated dimensions. For jewelry work, where a snapped 0.5mm bit ends the session, spares in the box are part of the value.
Project Match
- PCB and circuit work: the uxcell 0.7mm or 0.8mm, with fully stated edge, shank and overall dimensions.
- Jewelry drilling across sizes: the ApplianPar or Sunxeke 0.3mm to 1.2mm sets, ten sizes in one box.
- Stone and glass carving: the Sunxeke, which states stone grinding among its uses.
- 3D printer nozzle cleaning: the Sunxeke, which the listing names for the job.
How the scores add up
Each bit set is scored on performance, build, value, safety and warranty. How we pick explains the weights. For micro bits, safety points come from named certifications or safety features stated on the listing, and none of these listings names any, so all four score zero on safety.
| Product | HQ Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| ApplianPar 50-Pack | 9.6 | 30 | 20 | 22 | n/a | 0 |
| Sunxeke 50-Pc Set | 9.6 | 29 | 20 | 22 | n/a | 0 |
| uxcell 0.7mm 10-Pc | 9.5 | 27 | 20 | 19 | n/a | 0 |
| uxcell 0.8mm 10-Pc | 9.5 | 27 | 19 | 19 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
FAQ: lasers and CNC
What bit sizes do I need for jewelry?
A 0.3mm to 1.2mm set covers most jewelry drilling and engraving, with ten sizes to choose from. Buy a single-size 10 pack, like the 0.7mm or 0.8mm uxcell sets, when one hole size repeats across a production run.
Will these fit a Dremel or rotary tool?
The uxcell sets state a 3mm shank, about 1/8 in, which fits common rotary tool collets. The ApplianPar names Dremel in its title. Confirm your collet size against the stated shank before ordering.
Carbide or high speed steel?
Carbide, per these listings. All four state carbide in the title or bullets. The uxcell 0.8mm spec table says high speed steel, but the title and bullets say tungsten carbide, and per the site rules the title and bullets win.
Why do micro bits snap?
Side load and too much pressure. The uxcell listings state the spiral flute gives a sharper cutting edge that reduces cutting force. Let the bit cut at its own pace, keep the workpiece clamped, and keep spares from the 50-piece sets on hand.
Two flutes or three?
Three sets here state 2 spiral flutes; the ApplianPar states 3 flutes with a 118 degree cutting angle. Either cuts jewelry-scale work; the stated difference is in the listing, not a verdict from us.
