Tungsten carbide tip is durable when drilling in concrete and brick. The deep single flute removes drilling dust fast. Bit has a zinc finish. Country of Origin:China.
Based on our own experience, these industrial drill bits are outstanding for their durability and versatility. The tungsten carbide material ensures a longer lifespan and consistent performance on various materials from wood to concrete. However, these bits can be a bit pricier than other options on the market. Overall the investment is worth it for the quality and reliability of these cutting tools..
Pros
Long-lasting durability due to the tungsten carbide material.
Cons
May require a higher initial investment compared to less durable tools.
Like most other cheap tools. There's no quality there. The hammer drill drilled 11 3.5 inch deep holes in the concrete and the shank broke away from the rest of the bit. About halfway to the drilled holes I noticed a definite wobble that started to develop as if the heat was too much and the metal was softening, Irvine isn't the same as before.
