A higher helix angle means these end mills clear more chips than other roughing cobalt steel end mills, making them better for milling aluminum, brass, and bronze. Serrations along the cutting edge act as chip breakers, so they can remove large amounts of material at high speeds.
Since most 3 flute end mills only have one edge that is center cutting, both cut to the center on a 2 flute end mill, making them the better choice when using the bottom of the end mill. Helix Angle: A lesser helix angle will run cooler—since it's spending less time in the aluminum. A higher helix is smoother cutting, gives a great surface ...

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.
In this paper, end milling experiments on aluminum alloy 2024T351 were carried out to study the influence of end mill geometry on milling force and surface integrity of the machined parts. Machining using a 16mmdiameter tool having a helix angle of 35° produced high force value and also generated chatter marks on the machined work surface.
"End mills with a 60o helix angle are used on nonferrous materials like aluminum and even highnickelcontent alloys in finishing applications. In general, a variable pitch end mill with a 35 to 38o helix angle is the most common we see in the industry because it has a good balance of edge strength and core diameter, and it's a little bit ...

Aluminum end mills come in several helix angles the most common being 30, 45, and 60 degrees. 30 degrees is the most popular option, offering a pleasant blend of robustness, speed, and finish. 45 degrees can cut somewhat faster than its counterpart, but it will generate a rougher surface.

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.
Material: solid carbide. Shank diameter: 6mm. Cutter diameter: 6mm. Overall length: 50mm. Flute length: 22mm. Helix angle: 45°. Each of these features has a direct influence on how the end mill will behave during a machining operation and on the cutting possibilities in terms of performance and shapes.
End Mill Helix Angle. The helix angle of a tool is measured by the angle formed between the centerline of the tool and a straight line tangent along the cutting edge. A higher helix angle used for finishing (45°, for example) wraps around the tool faster and makes for a more aggressive cut.
The end mills for aluminum are a versatile and highquality set of cutting tools that are designed to provide superior performance and precision in aluminum processing.

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 ...

Helix angles generally come as low as 12° to as high as 60°. Most general purpose end mills use between a 25° and 30° angle where basic sharpness and cutting edge strength is maintained. Increasing the helix angle improves stock removal and is useful in machining at increased speeds and feeds.
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 ...
A higher helix angle means these end mills clear more chips than other roughing cobalt steel end mills, making them better for milling aluminum, brass, and bronze. Serrations along the cutting edge act as chip breakers, so they can remove large amounts of material at high speeds.
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.
