The 20mm Roughing Endmill is a high-performance solid carbide cutting tool designed for aggressive material removal in CNC milling operations. It is engineered for roughing applications, efficiently machining tough materials like steel, stainless steel, cast iron, and other metals (compatible with P20 die steel as per ISO classification).

• Material: Solid carbide for superior hardness, heat resistance, and durability
• Diameter: 20mm - Ideal for medium to heavy roughing operations
• Coating: Often features TiAlN, AlCrN, or uncoated (depending on model), enhancing wear resistance and thermal stability
• Flute Design: Coarse pitch (4 flutes) for better chip evacuation and reduced vibration
• Helix Angle: Optimized for high feed rates and reduced cutting forces
• Roughing-Specific Geometry: Serrated/knurled cutting edges break chips into smaller pieces, reducing load and heat buildup

• Primary Use: Heavy stock removal (roughing) before finishing passes
• Materials: Carbon steel, alloy steel (SC45, P20), stainless steel (304, 316), cast iron, tool steels
• Machines: Compatible with CNC milling machines, machining centers

• High Efficiency: Removes material faster than finishing endmills
• Vibration Damping: Serrated edges reduce chatter
• Long Tool Life: Carbide substrate resists wear and high temperatures
• Chip Control: Prevents chip re-cutting and clogging
