What the bit listings tell you
We compared 5 bit listings for this guide. Only the Dremel 9924 listing states a warranty term, and the BIGOU and Asieg sets are the only listings that name a storage case. Several listings leave out basics: the 9924 listing states no shank or cutting size, the XFQUIJ listing states no hardness figure, and the Asieg spec table lists tool figures of 200 watts and an ac power source beside bit figures. Read the parts list, not just the title.
Buying guide: best engraving bit for metal under 20
Shank size
Shank size decides fit. The BIGOU, 9903HP and Asieg listings state a 1/8 inch shank, with the BIGOU listing giving 3mm beside the 1/8 inch figure and the 9903HP listing giving 3.2mm beside it. The XFQUIJ listing states a 2.35mm shank, stated as 0.1 inch. The 9924 listing states no shank figure, so fit there rests on the engraver model it names.
Cutting size and shape
Cutting size and shape decide the mark. The BIGOU heads are 6mm across 10 profiles, the Asieg set spans 1/4 inch and 1/8 inch cutting diameters, and the 9903HP ball nose works at 3.2mm. The XFQUIJ heads are 1mm for precise work, and the 9924 is a carbide point for fine lines to deep grooves. Match the head to the line width the project needs, and check the shape list before ordering a set.
Set size and storage
Set size decides how many shapes arrive in the box. The Asieg set holds 20 burrs plus 2 three jaw chucks, the BIGOU set holds 10 burrs, and the XFQUIJ set holds 6 bits in 6 shapes. The Dremel listings hold 1 bit each. The BIGOU and Asieg sets name a case, and the other listings name no case.
Coating and hardness
Coating and hardness figures separate the carbide claims. The 9903HP listing adds a titanium nitride coating over tungsten carbide, the BIGOU listing gives machining hardness reaching HRC70, and the Asieg listing gives hardness up to HRC80, higher than the HRC70 of steel as the maker lists. The XFQUIJ listing claims high hardness with no figure, and the 9924 listing states no hardness figure. Treat unfigured hardness claims as maker words, not measurements.
Warranty and safety naming
Warranty and safety naming are thin across these listings. Only the 9924 listing states a warranty term, Product Defects Only – 1 Year, while the 9903HP listing states Product Defects Only with no term. Safety naming rests on the cases: the BIGOU listing describes a durable plastic case for safety storage, and the Asieg listing describes a small case for safety storage and protection. The other listings name no safety feature.
Wear eye protection, clamp the workpiece down, and keep hands clear of a spinning bit. Stay with the tool while it cuts, and let a bit stop before setting it down.

How the scores add up
Each bit is scored on performance, build, value, safety and warranty. For engraving bits, safety points come from named storage and handling features, such as a case for storage. Only the Dremel 9924 listing states a warranty term, and the other listings state no warranty term.

| Dremel 9924 Point Bit | 9.3 | 24 | 19 | 16 | 0 | 2 |
