What to know before buying
Listing details to confirm
Listing details have inconsistent format and scope: the title and size name specify a 1/4-inch shank and 1/4-inch cutting diameter, while a dimensions field lists overall dimensions as 0.64 x 0.64 x 5 cm and the model text includes a separate 6.22 suffix. Confirm the desired bit dimensions and model before ordering. The listing also describes a five-piece set but names only a model number in the included-components field. The stated ±0.02 mm precision, 25°~28° helix angle and 50 mm overall length are manufacturer claims, not independently verified.

Customer feedback highlights perceived sharpness, cutting performance and general quality, with reported use on anodized aluminum and cast acrylic. That feedback is relevant to buyers considering the listed materials, but it does not establish results for every material or setup. Reports on long-term durability are mixed, so buyers planning sustained use should weigh that uncertainty. Aggregate ratings are mostly five-star, alongside a smaller spread of lower ratings.
