Dormer S904 Carbide MC-X Plain Shank Multi Flute End Mill

The 20mm diameter Dormer S904 Carbide MC-X Plain Shank Multi Flute End Mill represents the largest size in this range, designed for maximum material removal in heavy-duty machining operations. This substantial diameter provides outstanding rigidity for aggressive shoulder milling across free-machining steels, alloy steels, cast iron variants and copper alloys in demanding industrial applications.

Solid carbide construction ensures this end mill maintains its cutting performance through extended production runs, whilst the bright finish facilitates efficient chip evacuation during high-volume material removal. The 4-flute design combined with optimised geometry delivers smooth, controlled cutting action suitable for professional machinists requiring reliable performance from large-diameter cutters in workshop and production environments.

Features and Benefits:
• Solid carbide material for exceptional longevity
• Bright uncoated finish for optimal chip flow
• 4 flutes deliver stable cutting performance
• 30° helix angle ensures smooth operation
• 12° rake angle optimises cutting efficiency
• Medium cut length for general purpose use
• DIN 6535 HA plain shank design
• h12 tolerance ensures precision
• Chamfered corner edges prevent chipping
• Suitable for radial, diagonal and axial operations
