As my tests showed this industrial drill bit didn't hold up to its advertised 10mm size, and the 1mm diameter straight shaft made it difficult to control for precision drilling. The only positive was the affordable price point, but its not worth sacrificing functionality for cost savings .overall, I would not recommend this product for anyone in need of reliable cutting tools..
Pros
Durable and long-lasting abrasive.
Cons
Potentially too abrasive and may cause damage to certain surfaces if not used properly.
After I put it to the test, this industrial and scientific drill bit is top-notch! It cuts through sturdy materials with ease and is incredibly durable .Its titanium construction is impressive and enhances its precision. The only con is that it may require sharpening frequently especially with heavy use. Overall, I highly recommend this cutting tool for professionals in need of a reliable drill bit..
