What Customers Are Saying
Most customers praise these drill bits for sharp performance and clean drilling through metal, wood, and aluminum when they function properly. However, many report significant durability issues, with bits breaking or shattering unexpectedly during light-duty tasks like drilling soft wood or pre-drilling deck screws. Some describe the material as brittle and prone to snapping within seconds or after only a few holes. Despite these concerns, satisfied users highlight long-lasting performance under repeated use and appreciate the hex shank design. Overall, performance appears inconsistent—some bits excel while others fail prematurely.

Wrong drill bits.
Would Not RecommendWasted money. They were chosen by an employee for me to use with electric screwdriver I also bought and they did not fit. Could not return them because I had already thrown away my receipt and the package they came in.
