Square End Mill for Aluminum Machining | AEX Series

The AEX square end mill for aluminum machining is designed for high-speed slotting, side milling, pocket machining, shoulder machining, and flat surface milling of aluminum and other non-ferrous materials.

AEX is Dohre's dedicated aluminum end mill series. This square end mill is suitable for aluminum parts that require sharp cutting, smooth chip evacuation, low cutting resistance, and clean machined edges.

Compared with ball nose tools, square end mills are more suitable for straight walls, slots, pockets, flat bottoms, and shoulder features. The square end geometry helps improve machining efficiency and maintain clear part edges during aluminum milling.

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 reduce burr formation during slotting and side milling.

Fine-Grain Carbide Material
The AEX square 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

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 slotting, side milling, and pocket machining.

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 roughing, slotting, and high-speed aluminum cutting.

AEX square end mills are especially suitable for aluminum machining tasks where chip evacuation, edge sharpness, and cutting efficiency are important.

Suitable materials include:

•6000 series aluminum alloys

•6061 aluminum

•7000 series aluminum alloys

•7075 aluminum

•Aluminum-silicon alloys

•Magnesium alloys

•Copper 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

Dohre CNC focuses on precision grinding, edge consistency, dimensional stability, and strict inspection for aluminum machining tools. AEX series end mills are produced under controlled manufacturing processes to support stable cutting performance and reliable batch quality.

German Walter 5-Axis Grinding Machines

AEX series end mills are produced using German Walter 5-axis high-precision grinding machines. This helps maintain accurate flute geometry, stable dimensions, and consistent cutting edge quality.

Walter HELICHECK PLUS Inspection

Tool profile accuracy is inspected using German Walter HELICHECK PLUS measuring equipment. Profile accuracy can be controlled within 5 μm, helping ensure stable tool geometry and consistent machining accuracy.

50× Microscope Inspection

All tools are visually inspected under a 50× microscope to check cutting edge appearance. This helps ensure there is no edge chipping, serration, or visible cutting edge defect before shipment.

Stable Batch Quality

From carbide material selection to grinding, coating, edge inspection, and final quality control, Dohre follows strict production procedures to support consistent performance for standard products and OEM orders.

Q1: What is the AEX square end mill used for?
The AEX square end mill is designed for aluminum machining, especially for slotting, side milling, pocket machining, shoulder machining, and flat surface milling.

Q2: Can this square end mill machine 6061 aluminum?
Yes. It is suitable for 6000 series aluminum alloys, including 6061 aluminum. Sharp cutting geometry and smooth chip evacuation are important for reducing burrs and improving surface finish.

Q3: Can it be used for 7075 aluminum?
Yes. The AEX square end mill can be used for 7000 series aluminum alloys, including 7075 aluminum. For harder aluminum alloys, proper coating selection, rigid tool holding, and suitable cutting parameters help improve tool life and cutting stability.

Q4: Should I choose uncoated or DLC Rainbow coating?
For general aluminum machining, the uncoated version provides a sharp cutting edge and low cutting resistance. For aluminum alloys that are easy to stick to the tool, DLC Rainbow coating can help reduce built-up edge, improve chip flow, and support better surface finish.

Q5: Is this tool suitable for slotting aluminum?
Yes. The 55% small-core design and 45° helix angle provide larger chip space and smoother chip evacuation, making it suitable for aluminum slotting and pocket machining.

Q6: What is the difference between a square end mill and a ball nose end mill for aluminum?
A square end mill is better for flat surfaces, slots, pockets, shoulders, and side walls. A ball nose end mill is better for curved surfaces, 3D contours, complex profiles, and smooth surface finishing.

Q7: Can Dohre provide customized AEX square end mills?
Yes. Dohre supports OEM customization for AEX aluminum end mills, including diameter, flute length, overall length, shank size, coating, and special geometry requirements.
