The 2 flute have a larger gullet so more chip clearance. For smaller mills (below 1/2 inch) a 2 flute is a better roughing mill. For finish work or in hard materials, you need more cutting edges so use a 4 flute. If you're going to be working in aluminum, you'll want to get some "high Helix" end mills. The same principle applies between 2 and 4 ...

6063. This is really similar in function to 6061, but this is more common to see in extrusions. However, it isn't quite as stiff. This makes 6063 a little harder to machine; it's softer and gummier. When you're cutting aluminum extrusions, use really sharp tools, good lubrication, and watch your chip clearance.

Considering the helix angle is essential since it influences chip evacuation efficiency, component polish, tool life, and cycle times. End mills typically have straight or helical edges. Segments of 30°, 45°, and 50° make up the helix angle. Helix edge end milling cutters have been extensively used in milling because they offer light cutting ...

Hihelix end mills have several advantages inherited with their design. Simple math says that a an endmill with 45 degree helix angle directs 50% of the cutting force downward versus 25% for a 30 degree end mill. Main advantages are: Higher rake angle directs more of a cutting force downward.

Imagine the angle between the edge of the helix (the spiral flute) and the flat bottom of a standard endmill. A low helix endmill has an angle of 35 degrees or less whereas a high helix endmill has more than 35 degrees. A good roughing + finishing in one cutter compromise is a 38 degree helix angle.

Generally, a helix angle between 15 and 25 is ideal for machining aluminum. If the helix angle is too shallow, it will create higher cutting forces, and if it is too steep, it will produce lower cutting forces. Each helix angle has potential benefits and pitfalls, making the judicious choice of this factor essential for machining aluminum.

The helix angle is the angle between the mill's centerline and the tangent of its cutting edge. End mills with shallower angles have cutting edges that coil around them more slowly than those with higher angles. Helix angles matter a great deal for aluminum machining. For aluminum cutting, machinists typically use 45°, 50°, and 55° helix ...
