Review on Jobber Carbide Tipped Standard 50368 by Kevin Seaton

Industrial and Scientific buyers beware! As a result of my tests i determined that this industrial drill bit does not live up to its carbide tip reputation .While the bit had good initial penetration, it quickly dulled and failed to maintain its edge after minimal use. The only pro was its initial cutting speed. The major con is that it ultimately fails in quality and durability. I do not recommend this product for cutting tools..
