After trying this product, i am impressed with how easily it cuts through metal. The bi-metal material is durable and long-lasting, making it a great investment for industrial and scientific use. The hole saws and accessories are easy to use and the black color makes them stand out in my tool kit. The only con is that they are a bit pricey but the quality makes it worth it in the long run. Overall, I highly recommend these cutting tools..
Pros
Durable and long-lasting due to the bi-metal composition.
Cons
May require a specific drill size for optimal use.
The slanted slots on the side of this saw make it easier to eject the core and better remove sawdust while drilling, preventing the drill from overheating. Good upgrade for me.
