What Customers Are Saying
Customers overwhelmingly praise this drill bit for exceptional performance in concrete and masonry, with most highlighting how effortlessly it cuts through tough materials like old concrete and cinder block. Many report drilling 20 or more holes without degradation, and reviewers consistently note the bit remains sharp and effective under heavy use. The 4-cutter design is recognized for enhanced durability and cutting efficiency. Most customers consider it a top-tier performer that delivers reliable, long-lasting results. A few users reported premature dulling after just a couple of holes, and some note it won't cut through rebar, though these represent isolated cases significantly outweighed by positive feedback.

Awesome product

No Mandrel
Beware: Most everything shown on the website indicates the mandrel is included with this bit and it is not. This is a bit only. My local store did not have the mandrel I needed. Once I can use the bit I will add that info.

Great drill bit
Would RecommendGreat for drilling into concrete. You need a hammer drill for this drill bit to work best. I used this to drill holes into concrete to secure a rail. These drill bits did the job.

Not great for drilling on a brick wall
Would Not RecommendI bought this for drilling a hole on my brick wall based on recommendation from Lowes customer service people. This didn't work for me. It barely put a hole in the wall. The load is applying off centered even though i am using appropriate power tool.
