Ratings & Reviews for DEWALT 14 -Piece Assorted Assorted Cobalt alloy steel Jobber length Twist Drill Bit Set

What Customers Are Saying

The cobalt drill bits demonstrate mixed performance. Many users report the bits effectively drill through hardened steel, stainless steel, and other tough materials, with some describing them as highly capable. However, a significant number have experienced issues, including bits breaking, dulling, or failing to meet expectations, especially with smaller sizes. While the bits appear well-suited for challenging drilling tasks, the quality and durability seem inconsistent. Users recommend caution, slow speeds, and cutting oil when drilling, especially with smaller bit sizes.
