What Customers Are Saying

Customers overwhelmingly praise this masonry bit for exceptional performance drilling through concrete, brick, and block with ease, often describing it as cutting "like butter." Most report drilling dozens of holes—some 10 inches deep—without slowdown or overheating, completing jobs in record time. The bit maintains its edge through extended projects with 20 or more holes, and users appreciate the centering tip for accurate starts and reduced slippage. A few experienced dulling on extremely thick concrete or rebar, but the vast majority consider it durable, reliable, and highly recommended for demanding applications.

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.
