I've been using the BRUFER auger drill for a few weeks now, and I must say that it has exceeded my expectations. When I tried this product, I was surprised at how effortless it was to drill through thick pieces of wood and metal. Its sharp cutting edges made clean, precise holes every time. It definitely lives up to its name as a heavy-duty driller. The only cons I experienced was that it was a bit heavy and bulky. Overall, I highly recommend this product for any industrial and scientific drilling needs.
