The drill bit is usually a rotary cutting tool, often multi point. The bit is pressed against the workpiece and rotated at rates from hundreds to thousands of revolutions per minute<br \/><br \/>\r\n\r\n\r\n<strong>Small to medium diameter holes<\/strong><br \/>\r\nThere are three different drilling solutions to choose from: Solid carbide drills, exchangeable-tip drills and index able insert drills. Hole tolerance, length and diameter are three important parameters to consider when selecting drill type. Each solution has its advantages in different applications.<br \/><br \/>\r\n\r\n<strong>Indexable insert drills<\/strong><br \/>\r\nCoroDrill 880 is designed for productive drilling and is optimized for mid-range tolerance applications in all workpiece materials. CoroDrill 880 is a versatile tool that can do more than a conventional drill, e.g. boring.\r\n\r\n<ul>\r\n    <li>Step-by-step entrance with perfectly balanced cutting forces enables high penetration rates, reducing the hole costs and providing a stable hole quality\r\nFour true cutting edges for improved production economy on diameters above 14 mm (0.551 inch)<\/li>\r\n    <li>By pre-setting the CoroDrill 880, a closer hole tolerance can be achieved<\/li>\r\n    <li>Typical hole diameter area: 16-63.5 mm (0.630-2.500 inch)<\/li>\r\n<\/ul>\r\n\r\n<strong>Exchangeable-tip drills<\/strong><br \/>\r\nCoroDrill 870 offers high process security with safe chip evacuation for medium tolerance holes.\r\n<ul>\r\n    <li>Easy tip changing while tool is in the machine maximizing actual machining time<\/li>\r\n    <li>Optimized grades and geometries for various materials increase tool life and penetration rates<\/li>\r\n    <li>Typical hole diameter area: 12-26 mm (0.472-1.024 inch)<\/li>\r\n<\/ul>\r\n\r\n<strong>Solid carbide drills<\/strong><br \/>\r\nWe have a complete range of solid carbide drills for high-precision holes and deep bores.
