Across thousands of reviews on major retailers, buyers praise the bits’ durability in stainless and thicker steels, noting cleaner, faster holes and reduced walking. Common positives include the secure 3‑flat shank, accurate laser size marks, and a sturdy, well-organized case. Some users report slower cutting if high speed is used—recommendation is to drill at lower RPM with cutting fluid for best life. A few mention breakage on the smallest sizes, which is typical for thin bits under heavy pressure.
