According to my experience with this hole saw, it cuts through metal effortlessly and delivers precise cuts. The carbide tip is durable and long-lasting, making it ideal for industrial and scientific applications. The saw also features a convenient arbor system that makes it easy to install and remove .However, it can be a bit expensive compared to other hole saws on the market..
According to my experience this drill bit is not worth the money. The teeth were dull and barely made it through one use.The only positive aspect was that it fit my drill perfectly. However, that was not enough to make it WORTH the cost. save your money and invest in a better quality tool..
Pros
Efficiently drills holes in a variety of materials, including stainless steel and other metals, as well as wood and composite materials.
Cons
Requires a power drill to use, limiting its portability and accessibility for those without the necessary tools.
I had to cut through an extruded metal mesh in a plastered ceiling. He did his job very well. It's quite expensive for what it is. There is only 1 carbide tooth for each of its 7 sections and that's it. with a pilot drill and a mandrel, which increases the cost.
