This industrial drill bit is a must-have for any serious DIYer or professional .As a result of my tests, i determined THAT the drill bit cuts through metal with ease and precision. The arbor pilot feature is an added bonus that ensures accuracy in drilling with no slipping or wobbling. The bit is also durable and can withstand heavy use. However, the price may be a bit steep for occasional users. Overall, I highly recommend this product for anyone in the industrial and scientific field..
