What to know before buying
Listing details to confirm
The listing is internally contradictory: its title specifies 1 piece and a 16.5 mm tool, while the description calls this a six-piece set and lists diameters 6.3, 8.3, 10.4, 12.4, 16.5 and 20.5 mm. The exact supplied package and selected configuration are unconfirmed, so check the listing before purchase. The technical details also identify the brand as Ruko while the manufacturer field says Drittland.
Who is it for?
A good fit for
- Buyers needing a listed 16.5 mm countersink for metal deburring or countersinking.
- Workshop users considering a tool for steel, non-ferrous metals, stainless sheet or plastic, subject to the listing's package ambiguity.
Less suited to
- Buyers who need confirmed delivery of a six-diameter set without first checking the selected listing.
- Buyers needing a specification sheet with unambiguous manufacturer or package details.

Aggregate ratings lean positive, with most falling in the five-star category, but lower ratings are also present. Without written feedback, the ratings do not explain what buyers liked or disliked. They cannot resolve the listing's uncertainty about whether this is one tool or a six-piece set.
