What Customers Are Saying

Customers overwhelmingly praise the drill bit for exceptional concrete drilling performance, durability, and value. Most highlight its ability to cut through concrete efficiently with speed and minimal effort, with many noting it outperforms competing options and handles multiple projects without degradation. Reviewers consistently report the bit lasts significantly longer than alternatives, remaining effective across varied applications from fence posts to ceramic work. Many affirm strong value for the price and reliability. A small number report isolated issues like breakage or warping, though these represent less than 10% of feedback and often relate to improper use.

Not so Great

Would Not Recommend

While the packaging makes this sound like the best masonry drill bit ever, it didn't perform as well as some I already had that are worn. Not worth the price.

Try it out for yourself

Would Recommend

Bit performed well but effectiveness reduced after 10 drills, which trends against packaging promotion.

Fit regular drill

Would Recommend

I didn’t know what a SDS drill was but it fit a std 1/2 drill. Thought it took a bit long to drill through the substrate but it worked.

Not the best fit in your drill

Would Recommend

Got this to drill through a 4” concrete wall. While it worked just fine, it didn’t fit perfectly in the drill which led to some wobble.

Best Xtreme8 8-cutter carbide bit

The Xtreme8 8-cutter carbide bit performs significantly better than the 2-cutter carbide version. The 2-cutter bit is more prone to tip breakage and struggles when drilling through hard concrete or stone. In contrast, the 8-cutter carbide bit drills faster and more efficiently through tough materials like concrete and stone.
