## Before you buy

- 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.

## In the box

- 1 × 1-3/4 in. x 22 in. SDS-Max rotary hammer core bit (Included): The explicit contents list names this size, which conflicts with other listed dimensions. Confirm the selected listing.

## A good fit for

- Rotary-hammer users whose tool accepts an SDS-Max shank and who need a core bit in the listed size range.
- Buyers drilling concrete who prioritize a carbide-tipped centering bit and an integral core design.

## Less suited to

- Users whose rotary hammer does not accept an SDS-Max shank.
- Buyers who need a confirmed cutting diameter or overall length without first resolving the listing's size inconsistencies.

## Customer feedback

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.
- Positive themes: Feedback mentions fast drilling and positive perceived value.
- Negative themes: Some customers report teeth breaking off.
- Negative themes: 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.
