What to know before buying

Listing details to confirm

The listing is inconsistent on size: its title gives 1-3/4 inches, the details list a 2.63-inch cutting diameter, and the included-component name gives 1-3/4 inches. It also names 17- and 22-inch lengths in different title/detail text. Confirm the required diameter and overall length against the selected item before purchase. The stated 2-5/8-inch maximum core depth is a separate depth limit.

Who is it for?

A good fit for

Customer feedback describes strong cutting performance and speed, including reports of drilling through thick concrete. Durability feedback is mixed, with some customers saying the bit lasts well and others reporting broken teeth or difficulty removing pieces from the chuck. These reports are relevant to demanding concrete work, but they do not establish a guaranteed drilling time or service life. The listing's carbide teeth and wave design are product claims, not proof of customer-reported outcomes.

Positive themes

  • Customers report effective cutting through hard and thick concrete.
  • Feedback mentions fast drilling and positive perceived value.

Negative themes

  • Some customers report teeth breaking off.
  • Some report pieces jamming in the chuck or difficulty removing the bit.

Mixed feedback

  • Durability is described positively by some customers and negatively by others.
