What Customers Are Saying

Customers overwhelmingly praise this masonry bit for cutting through concrete, brick, and block with remarkable ease, often describing it as cutting "like butter." Most report drilling 20+ holes up to 10 inches deep without degradation, with many noting the bit maintains sharpness even after 24 to 36 holes. Reviewers highlight the centering tip for accurate hole starting and the four-cutter head design for efficient debris removal. A few users reported isolated issues like premature dulling or chuck fit problems, but these represent minimal feedback vastly outweighed by strong satisfaction and recommendations across the board.

5/8 inch masonry bit

This masonry bit just eased through the concrete like I was cutting wood. I pre drilled the holes with a 3/32 masonry bit then used the 5/8. I usually have to put a lot of pressure on masonry bits but this one went right in. Best bit I have

Great drill bit

Would Recommend

Bought this drill bit to drill 14 anchor holes in a concrete pad. This was by far the best concrete bit I have ever used. Each hole was 8” deep and the average time to drill each hole was less than 1 minute.

Thank you for sharing your experience. We’re sorry to hear that the bit did not hold its edge as expected. This is not the level of performance Bosch...
