The minimal difference in pricing compared to uncoated drills therefore earns itself back very quickly. Drills with a TiN-coated tip have the same advantages as fully TiN-coated drills. Because the flutes have been coated, you can expect the same results without paying the price for a fully TiN-coated drill.
