It cannot be confirmed. The verifier found no reference frame from the Stumpy Nubs video to match the AliExpress listing against. The candidate is a generic multi-size drill guide block covering 4–10mm holes, which is a common OEM form factor, but the original product's specs were not publicly documented in the source material.

Standard shipping from China typically takes 15–45 days. If the listing is fulfilled from a US or EU warehouse — check the shipping tab — delivery can drop to 10–15 days. AliExpress Choice items sometimes qualify for faster processing, but this specific listing's status was not confirmed at time of writing.

AliExpress Buyer Protection covers items that arrive damaged or significantly not as described — open a dispute within 15 days of delivery confirmation. At $1.54, the financial risk is minimal, but document the issue with photos immediately on arrival. Note that the listing currently has zero ratings, so there is no community history to gauge how the seller handles disputes.

This is a passive drill guide block — it requires no battery or power source. It is used in conjunction with a handheld drill or drill press; the user supplies the drill and bit. It is compatible with any drill accepting standard round-shank bits in the 4–10mm range.

The listed hole sizes are 4, 5, 6, 7, 8, 9, and 10mm — all metric. Common imperial sizes such as 5/16" (7.94mm) or 3/8" (9.53mm) are close but not exact matches. If your project requires precise imperial-size guidance, metric bushings may introduce enough play to affect accuracy.

The AliExpress listing does not specify the material explicitly. At a $1.54 price point, the body is almost certainly an injection-molded plastic rather than aluminum or hardened steel. Plastic guides are adequate for occasional light-duty use in wood but will wear faster than metal guides when used repeatedly with larger bits or on harder materials.

Drill guide blocks of this form factor typically assist with keeping a bit perpendicular to the workpiece surface, which is their primary function. Depth-stop capability depends on the specific design — the listing does not confirm a built-in depth collar. If precise depth control is critical to your application, verify this feature in the listing photos before purchasing.

The listing shows a two-tone brown/black body in one apparent configuration covering the 4–10mm range as a set. Separate single-size bushings or larger-diameter variants (above 10mm) do not appear to be offered within this specific listing. If you need guidance for bits larger than 10mm, a different listing would be required.
