Sandvik CoroDrill 860 vs Walter DC170 Supreme
CoroDrill 860 and DC170 Supreme are high-performance solid-carbide drill families. CoroDrill 860 is segmented by material-focused geometries, while DC170 Supreme emphasizes continuous land guidance, coolant coverage and process security in steel and cast iron.
Side-by-side comparison
| Category | Sandvik CoroDrill 860 | Walter DC170 Supreme |
|---|---|---|
| Portfolio strategy | GM, SM and SD geometries separate multi-material, titanium and nickel-alloy applications. | A focused Supreme platform for ISO P and K with multiple depth ratios. |
| Guidance and stability | Optimized cutting edges and flute designs vary by geometry to balance penetration, accuracy and chip control. | A distinctive land design continuously guides the drill and adds carbide mass behind the cutting edge. |
| Selection priority | Start with workpiece material and select the matching 860 geometry. | Start with steel or cast-iron application, depth ratio and difficult entry or exit conditions. |
Best fit by application
Sandvik CoroDrill 860
- Choose CoroDrill 860 when a material-specific GM, SM or SD geometry directly matches the application.
