Cat-5 Carbide Roughing End Mill

1/4" Roughing End Mill
Tungsten Carbide • Nano Blue Coated

Overview
Built for fast material removal with lower cutting forces than a standard end mill. The serrated cutting profile breaks chips into smaller pieces to reduce spindle load, chatter, and vibration, making it a strong choice for roughing passes on spindle-driven CNC machines.

Best For

• Rapid stock removal
• Roughing passes
• Pocket clearing
• Bulk material removal

Why Choose It

• Removes material quickly with reduced spindle load
• Serrated flutes help reduce chatter and vibration
• Nano Blue coating improves heat resistance and tool life
• Ideal before finishing passes

Starting Parameters
Start conservatively, then increase as machine rigidity allows.

• Spindle: 14,000–18,000 RPM
• Feed: 180–280 IPM
• Plunge: 50–80 IPM
• Cut Strategy: Use deeper passes and higher feed than a standard end mill, then follow with a finishing tool

Compatible Materials

• Hardwood
• Softwood
• Plywood
• MDF
• Plastics
