AI Review Summary:

Across major retailers, buyers praise the set’s durability in stainless and cast iron, noting fast starts and reduced walking due to the split-point tips. Many highlight clean holes and long life compared with black oxide bits, with the case organization appreciated for size visibility. Neutral feedback mentions that aggressive feed rates can still overheat bits and recommends cutting fluid. A recurring complaint is that the largest sizes dull sooner under heavy continuous drilling or if used in impact drivers. Representative quotes: “Chews through 1/4" stainless where my old set failed,” “Size markings are easy to read and stay visible,” and “Use lube and moderate speed—otherwise they’ll get hot.”
