The NA 3 Flute Aluminum Roughing End Mill is designed for high-efficiency stock removal in aluminum machining. Its 45° helix, large rake angle, coarse-tooth serrated edge, and large chip space help break and evacuate chips quickly during heavy cutting.
The NA 3 Flute Aluminum Roughing End Mill is designed for aggressive roughing operations where fast stock removal and efficient chip evacuation are critical.
Its coarse-tooth serrated cutting edge breaks continuous aluminum chips into smaller segments, reducing chip buildup in the cutting zone.
The tool also features a large rake angle and 45° helix angle to create a sharper cutting action and reduce cutting resistance.
Combined with generous chip space, this geometry allows the NA to handle large cutting loads while maintaining efficient chip evacuation.
Long, continuous chips can become a major problem during aluminum roughing.
The NA uses a serrated cutting edge to break continuous chips into shorter segments before they pass through the flutes.
This helps reduce chip entanglement and supports faster chip removal during heavy stock-removal operations.
A 45° helix angle promotes a smoother cutting action and helps direct chips away from the cutting zone.
The large rake angle creates a sharper cutting edge, reducing cutting resistance and allowing the tool to enter the aluminum more freely.
This geometry is particularly suited to high-efficiency aluminum roughing.
The NA uses a 0.6 μm carbide substrate designed to balance hardness and toughness.
This provides the cutting edge with the strength required for heavy aluminum roughing.
The 3-flute configuration provides a balance between cutting-edge engagement and available chip space.
It is designed for efficient material removal while maintaining enough flute capacity for chip evacuation.
The coarse-tooth cutting profile breaks continuous chips into shorter pieces.
This helps reduce chip packing and allows chips to move through the flutes more efficiently.
The large chip space provides room for the higher chip volume generated during roughing.
This supports smoother chip evacuation and helps reduce chip recutting during heavy milling.
The large rake angle sharpens the cutting action and reduces cutting resistance.
This allows the tool to remove aluminum more efficiently while reducing cutting load on the machine.
The 45° helix angle supports smooth engagement and directs chips upward through the flutes.
Combined with the serrated edge, it helps maintain efficient chip evacuation during aggressive cutting.
Aluminum can produce long, continuous chips during roughing.
The serrated cutting edge breaks these chips into shorter segments, making them easier to evacuate.
Large chip volumes can overload conventional flute spaces.
The NA combines a coarse-tooth design with large chip space to provide greater chip capacity during heavy stock removal.
Heavy aluminum milling can place a substantial load on the cutting tool and spindle.
The large rake angle creates a sharper cutting action and helps reduce cutting resistance.
Finishing-oriented tools are not designed for aggressive stock removal.
The NA is specifically configured for high material removal rates, making it suitable for the roughing stage before semi-finishing and finishing.
The NA is primarily designed for:
The appropriate tool configuration and cutting parameters should be selected according to the specific aluminum alloy, machine capability, tool diameter, workpiece geometry, and machining strategy.
The NA 3 Flute Aluminum Roughing End Mill is suitable for:
It is particularly suitable for operations where large amounts of aluminum stock need to be removed quickly and efficiently.

The NA is designed specifically for high-volume aluminum stock removal, rather than finishing operations.
Its serrated cutting edge breaks continuous chips, while the large chip spaces provide sufficient capacity for heavy cutting.
The combination of a large rake angle and 45° helix further reduces cutting resistance and supports efficient material removal.
Different aluminum components may require specific tool diameters, cutting lengths, flute configurations, or roughing geometries.
