Technical notes
- The AEX corner radius end mill for aluminum machining is designed for shoulder milling, side-wall finishing, pocket machining, step machining, dynamic milling, and profile machining of aluminum and other non-ferrous materials.
- AEX is KERNVEX's dedicated aluminum end mill series. This corner radius tool is suitable for aluminum parts that require stronger edge protection, smooth chip evacuation, lower cutting resistance, and stable wall quality.
- Unlike a sharp-corner square end mill, the corner radius design helps reduce stress concentration at the cutting edge. This can lower the risk of corner chipping during shoulder milling, side-wall machining, and high-speed aluminum cutting.
- Compared with a ball nose end mill, the AEX corner radius end mill provides better efficiency and dimensional control when machining straight walls, shoulders, steps, and pocket features.
- Made from imported fine-grain carbide with 0.8 μm grain size and 10% cobalt content , the tool provides stable edge strength, sharp cutting performance, and reliable wear resistance for continuous aluminum machining.
- Its positive rake geometry, 55% small-core design, and 45° helix angle help reduce cutting resistance, improve chip evacuation, and support smoother cutting in high-speed aluminum milling.
- Fine-Grain Carbide Material The AEX corner radius end mill is produced from imported carbide rods with 0.8 μm grain size and 10% cobalt content . This carbide substrate provides a good balance of hardness, toughness, and wear resistance for aluminum and non-ferrous material machining.
- Uncoated or DLC Rainbow Coating The tool is available in uncoated and DLC Rainbow coated versions. The uncoated version provides a sharp cutting edge for smooth aluminum cutting, while the DLC Rainbow coated version helps reduce friction, improve anti-adhesion performance, and lower the risk of built-up edge.
- Aluminum adhesion is a common machining issue, especially in high-speed cutting or deep slotting. More details are explained in our guide: Why Does Aluminum Stick to an End Mill
- Corner Radius Design for Edge Protection The corner radius design helps strengthen the cutting edge and reduce stress concentration during shoulder milling, side-wall finishing, and pocket machining.
- This makes the tool more stable than a sharp-corner square end mill when machining aluminum parts that require better tool life, cleaner wall edges, and reduced corner wear.
- Positive Rake Geometry The tool adopts a 6° end rake angle and 12° side rake angle . This sharp cutting geometry helps reduce cutting resistance, improve cutting smoothness, and minimize burr formation during aluminum shoulder milling and side-wall finishing.
- Precision-Ground Cutting Edge The cutting edge is precision-ground with a 1200-grit grinding wheel to maintain edge sharpness. This helps reduce burrs, avoid uneven surface marks, and improve the final surface quality of aluminum parts.
- 55% Core Diameter and 45° Helix Angle The tool uses a 55% small-core diameter and 45° helix angle . The smaller core provides larger chip space, while the high helix angle supports smoother chip evacuation and lower cutting resistance during dynamic milling, pocket machining, and high-speed aluminum cutting.
- AEX corner radius end mills are especially suitable for aluminum machining tasks where stronger edge protection, stable wall quality, and smooth chip evacuation are required.
- Suitable materials include:
- •6000 series aluminum alloys
- •7000 series aluminum alloys
- •Aluminum-silicon alloys
- •Magnesium alloys
- •Engineering plastics
- For 6061 aluminum machining, sharp cutting edges and smooth chip evacuation are important for reducing burrs and improving surface finish. More selection details can be found in: Best End Mill for 6061 Aluminum
- For harder aluminum alloys such as 7075, coating selection, tool rigidity, and cutting parameters become more important. Related guide: Best End Mill for 7075 Aluminum
