Based on my experience, this bit cuts through metal like butter reducing the time spent on drilling .Its unique design is highly effective making it durable enough to withstand heavy-duty projects. However, the price is a little bit high for those who are on a budget. Overall, a great investment for professionals and DIY enthusiasts..
Pros
Efficiently and quickly drills through concrete, brick, and other hard materials
Cons
Requires a powerful drill motor to operate effectively
Seems to be faster than most other step exercises I've used. So far it's holding up well after drilling about 10 holes in a 1/2" steel plate.
Pros
