CoroDrill Grades Offer Predictable Wear Patterns
Sandvik Coromant adds three grades for its CoroDrill 870 exchangeable-tip drill.
The GC4344, GC3334 and GC2334 grades for the CoroDrill 870 are produced with Zertivo, a PVD production technology developed by Sandvik Coromant. This technology maintains the the properties of the previous technology and is said to improve edge line security, chipping resistance and overall wear resistance properties.
Available in various geometries, the latest grades are said to be versatile and cover applications in varied ISO materials, although they are designed for steel, stainless steel and cast iron. According to the company, all grades are designed to deliver specific enhancements related to common wear issues in drilling.
Designed for the intermediate hole-tolerance range of H9 to H10, the exchangeable-tip drill saves time and reduces cost per hole, the company says. The drills can be tailored to applications through a selection of diameter, length, step or chamfer possibilities. The drill is available in a diameter range from 10 to 33 mm (0.394" to 1.299") and a depth capacity from 3 × D to 12 × D.
