Recommended Series: CoroDrill® 860-PM

For production drilling where tool selection depends on the workpiece material, Sandvik Coromant’s CoroDrill® 860 family offers material-specific options for steel, stainless steel, non-ferrous materials, titanium, nickel-based HRSA, and multi-material applications.

CoroDrill® 860-PM is designed for high-productivity short-hole drilling in ISO P materials such as carbon steel and alloy steel. It supports stable tool life in continuous production and is suitable for automotive components such as valve bodies and manifolds.

The drill can achieve H8–H9 hole tolerances, helping reduce cycle time and rework. Its flute geometry, substrate, and multilayer PVD coating support chip evacuation, surface quality, and lower cutting resistance under thermal load.

Best Fit Applications

• High-productivity drilling of short holes
• Steel-focused production drilling with ISO P materials
• Automotive components such as valve bodies and manifolds
• Applications requiring H8–H9 hole tolerances
• Production lines where drill selection is based on workpiece material group
