Sandvik Coromant CoroDrill 860
CoroDrill 860 is a Sandvik Coromant solid-carbide drill platform split into application-specific GM, PM, SM, and NM variants. The suffix, geometry, grade, diameter, usable length, tolerance, and order code are essential because the variants target different material groups and are not one universal drill.
Product system overview
CoroDrill 860 is a Sandvik Coromant solid-carbide drill platform split into application-specific GM, PM, SM, and NM variants. The suffix, geometry, grade, diameter, usable length, tolerance, and order code are essential because the variants target different material groups and are not one universal drill.
Industries and applications
- CoroDrill 860-GM for broad multi-material drilling where the exact GM item supports the work material.
- CoroDrill 860-PM, SM, and NM variants for steel, heat-resistant-superalloy, and nonferrous-focused applications respectively.
- Production drilling that benefits from downloadable tool models, drawings, GTC packages, and item-specific cutting data.
Technical and quote details
- Official product records use complete ISO/ANSI ordering codes and separate Sandvik material IDs.
- Cited variants publish H8 or H9 achievable hole tolerance depending on the application-specific family and item.
- PM, GM, SM, and NM items carry different point geometry, coating, grade, material coverage, and usable-length ratios.
- Machine-side connections in the cited examples are metric cylindrical DIN 6535-style shanks with h6 connection-diameter tolerance.
- Item pages provide basic and detailed STP, DXF, GTC, and basic tool-data downloads.

Selection notes
Store the complete ordering code and material ID, including application suffix and grade, rather than shortening the record to CoroDrill 860.
When an official page declares an item obsolete, preserve the original code and the named replacement relationship.
Variables to validate
- The 860 family suffix is an application distinction, not optional naming; GM, PM, SM, and NM data should not be blended.
- Sandvik explicitly marks some earlier 4234-grade PM items obsolete and names replacement P1BM items, so grade lifecycle must be retained.
- Coolant, runout, holder, depth ratio, entry and exit, and machine stability must be checked against the exact item.
