Based on my observations with this industrial drill bit, I must say it's remarkable. Its cutting ability is very aggressive with great precision.The design of the drill bit allows it to penetrate any material with ease, especially hard metal. i love how durable it is, AND it has significantly saved time and efforts on my project. As for cons, the only downside is that its not beginner-friendly and requires an experienced hand. Overall I highly recommend this drill bit for any industrial and scientific project..
