As a hesitant buyer, I was pleasantly surprised with the Uxcell 1.5mm Shank TiN Coated Carbide drill bit .This cutting tool is definitely an essential item in the industrial and scientific fields! As a result of my tests I determined that it's durable and provides accurate results. However, the only downfall I experienced was that it tended to overheat after extended use. Overall, this product is worth investing in for any industrial professional seeking TO obtain quality results..
