A glass ornament with a name etched into it sells at every holiday market, and a personalized wine glass never sits long on a craft table. Diamond burrs are the bits that cut glass: tiny grinding heads that abrade the surface instead of slicing it. The best engraving bit for glass under $15 is a diamond burr set in a fine grit on a shank that fits the rotary tool, with enough head shapes for the work. This guide compares five diamond burr sets sold for glass engraving, scored on grit, build, value, safety statements and warranty, using only what each listing publishes.

Buying guide: choosing the best engraving bit for glass under $15
Grit: 60, 120 or 150 mesh
Three sets here are 120 grit, which the listings aim at fine detail work on glass, ceramic and stone. The Sworker 60-grit set is the coarse one, described as coarse in its spec table, for aggressive material removal. The Wolfride set uses 150 mesh with 1 to 3mm heads for tiny detail. For fine lines on glass, the finer grits fit; for shaping, the coarse set cuts faster.
Shank size and the collet it fits
Four of the five sets state a 1/8 in shank, the standard collet size on Dremel-style rotary tools, and the listings name that compatibility directly. The Wolfride set states a 2.35mm shank instead, so it needs a collet that size. Check the shank against the collet before buying: a burr that does not fit never cuts.
Cooling and the warranty in writing
The shengbenhao and both Sworker listings say to use water to cool the diamond bits, which matters on glass because heat cracks it. Only the two Sworker sets state a warranty term, the 5-year returnless replacement. The other three state no warranty term, so the purchase rests on the listing alone.
Project Match
- Fine glass engraving detail: Sworker 120-Grit 20-Pc, 120 grit in 6 head shapes.
- Aggressive shaping and removal: Sworker 60-Grit 20-Pc, coarse 60 grit in 10 shapes.
- Most head shapes: DRILAX 120-Grit 20-Pc, 20 shapes for glass and stone.
- Tiny detail bits: Wolfride 30-Pc Set, 1 to 3mm heads in 150 mesh.
- Starter set with a box: shengbenhao 20-Pc Set, 120 grit with a plastic box.
How the scores add up
Each set is scored on performance, build, value, safety and warranty, with the weights published on our How We Pick page. A spec the listing does not publish scores nothing. Only the two Sworker sets state a warranty term, the 5-year returnless replacement, and no listing states a safety certification.
| Product | HQ Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Sworker 120-Grit 20-Pc | 9.6 | 29 | 20 | 20 | n/a | 3 |
| Sworker 60-Grit 20-Pc | 9.6 | 28 | 20 | 20 | n/a | 3 |

| shengbenhao 20-Pc Set | 9.5 | 28 | 19 | 20 | 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
Do I need water when engraving glass with diamond burrs?
Yes, per the listings: the shengbenhao and both Sworker listings say to use water to cool the diamond bits. Heat is the enemy of glass.
What grit is best for glass engraving?
Three sets here are 120 grit, which the listings aim at fine detail work. The Sworker 60-grit set is the coarse option for aggressive removal, and the Wolfride 150-mesh set covers tiny detail.
Will these bits fit my rotary tool?
Four sets state a 1/8 in shank, which the listings tie to Dremel-style collets. The Wolfride set states a 2.35mm shank, so it needs a matching collet.
Which sets state a warranty?
The two Sworker sets state a 5-year returnless replacement. The DRILAX, Wolfride and shengbenhao listings state no warranty term.
Can these burrs work metal too?
The Sworker listings name steel and metal among their many uses, and the Wolfride names metal. All five name glass and ceramic, which is what this guide scores them on.
