Sandvik Coromant has expanded its CoroDrill Dura 462 family with solid carbide deep-hole drills for applications from 12×D to 30×D.
Sandvik Coromant has expanded its CoroDrill Dura 462 family with solid carbide deep-hole drills for applications from 12×D to 30×D.
The drills combine grade X2BM, Zertivo 2.0 PVD coating and a micro-grained carbide substrate for multi-material drilling. The geometry incorporates a refined flute design, offset double margins, double gashes, blended root radii and a 135-degree point angle.
The company says these features address stability, cutting forces, hole quality and chip evacuation in deep-hole applications. For holes deeper than 15×D, it recommends a corresponding CoroDrill Dura 462 short-hole drill at 3×D or 5×D to create the pilot hole.
According to Sandvik Coromant, customer field trials against competing tools produced an average 45% increase in tool life and a 25% productivity increase. These are company-reported trial results.
The drills are designed for multiple reconditioning cycles and extend a family that also covers micro and short-hole applications.
