What Customers Are Saying

Customers report mixed results with these drill bits. Many praise sharpness, clean drilling, and excellent value, particularly for metal work and controlled applications like drill presses. However, a substantial number experience sudden breakage during first use or with minimal pressure in wood, aluminum, and composite materials, describing the bits as brittle or poor quality. Some note inconsistent performance depending on usage context and material type. Despite durability concerns, most customers who experience successful use find them worthwhile for the price.

Eh drill bit I would pass

Would Not Recommend

Maybe I was using it too hard or it didn't quite fit the different drills I used; but I was getting the same issue where the part in the drill (silver/grey portion) would spin with the drill but the actual bit would not spin/drill.

Drill bit

Kobalt brand drill bits are great for drilling into metal.

Was this Review Helpful ?

After trying other brands of drill bits, and finding out that don't drill into metal very well, I discovered that the Kobalt brand works best for metal drilling.
