What to know before buying

Listing details to confirm

The listing describes the bit as 39.3 inches or 1000 mm long, while its dimensions field gives 39.37 inches. The supplied dimensions and listed total length are therefore inconsistent, so verify the intended overall length before purchase. The material description also contains the unclear phrase “一 type Carbide Tip,” leaving the specific carbide type unconfirmed.

Aggregate ratings lean favorable, but the available rating evidence is a small sample and includes some middle-star ratings. It does not explain customers’ reasons or establish how the bit performs. Buyers should use the clearly stated diameter and SDS-Plus fit for selection, and treat the long-length and material wording discrepancies as points to confirm.
