Cutting tool manufacturers are employing various design and manufacturing strategies in their drilling products as they strive to meet the demands of their customers for improved productivity. In applications as diverse as automotive, medical-device manufacturing, aerospace, and general engineering, manufacturers can choose from an array of highly engineered drills. They include high-penetration solid carbide drills, indexable-insert drills, replaceable-car-bide-tip drills and, increasingly, multiple-function drills to drill small holes, deep holes, and holes that are drilled, chamfered, and counterbored to eliminate secondary operations. Cutting tool manufacturers are drawing from advances in geometry, substrates, and coatings that enable them to introduce new product lines, expand existing products, and move custom-designed specials into their standard product offerings.
