Sandvik Coromant’s CoroDrill 880 represents a breakthrough in the U-drill evolution that allows substantially improved productivity in holemaking. The CoroDrill 880 offers cost savings potential to wind manufacturers due to the large number of short-hole drilling required in components like connector rings, hubs and rotor blades.
The CoroDrill 880 integrates step technology that provides outstanding cutting force balance, significantly improving both productivity and hole quality. The drill’s uniquely shaped center insert uses step technology to facilitate smooth entrance into the workpiece and perfectly balances cutting forces. This enables up to 100 percent increases in feed rates, cutting the cost per drilled hole in half.
The CoroDrill 880’s inserts present four cutting edges and wiper geometry, allowing for good insert economy and achieving a superior surface finish. A comprehensive selection of insert geometries and grades provides flexibility to optimize performance across a wide variety of applications and materials. The drill’s versatility allows it to excel in an array of applications, including helical interpolation, plunge drilling and boring.
The CoroDrill 880 family covers diameters from 0.473” to 2.5”, with lengths ranging from 2 to 5 times the diameter.
