The Rannb Cutting Toothed Bi Metal Drilling was perfect for the DIY project i was working on... My analysis of this product showed that it was durable and easy to use. It made clean cuts on both wood and metal surfaces. The saw was also versatile and worked well with both corded and cordless drills. The only downside was that it may not work as well for heavy-duty jobs but for a regular DIY user, it is a great and affordable product..
Pros
Efficiently drills through tough materials like metal and wood.
Cons
May break easily when used on very hard or dense surfaces.
Sharp and rather heavy drill. But! - The shank is not the standard 1/4 hex that professional impact drills work with. A drill with a fixed chuck must be used, which is inconvenient for professionals and wastes time.
