The basic edge shapes of end mills (helix groove shapes) are straight and helix. The helix angle can be divided into 30 degrees, 45 degrees, 50 degrees, and so on. Compared with a straight edge, helix edge end milling cutter has the advantages of light cutting, smooth cutting, high efficiency and wide application range, so it has been widely ...
Specialized helix angles for Aluminum are typically either 35°, 40°, or 45°. Variable helix tools are also available and make a great choice for reducing chatter and harmonics while also increasing material removal rates. A helix angle of 35° or 40° is a good choice for traditional roughing and slotting applications.
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.
With a wearresistant coating and high helix angle, these end mills provide excellent shearing and chip removal in stainless steel and titanium. Often used for slotting and pocketing cuts in mold and die making, these end mills have a 90° profile and rounded corners, which reduce flute breakage and chipping.
"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 ...

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.
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.
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.

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.
4. Kodiak Cutting Tools KCT129732 USA Made Carbide End Mill. This one is made in the USA. Kodiak Cutting Tools KCT129732 is a great carbide endmill to use for aluminum. It will lift up the chip to prevent from clogging up. There are 2 flutes and the space is wide.
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 ...
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.
A high helix angle, generally around 45 degrees is also desirable. The helix helps move chips up and out of the cutting zone and also generates an excellent surface finish. ... 7075, 6061, etc.), try the following: climb mill with a ½" diameter threeflute coated carbide end mill for aluminum. Take a widthofcut (WOC) of 30% of cutter ...
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 ...
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.
Set it with a full 1/2″ width of cut and let's be a little conservative on depth of cutwe'll use 1/4″. Now press the "Interpolate" button to bring up the Interpolation MiniCalculator. Let's say we're going to make a 2″ hole. GWizard tells us the ramp angle is degrees and our adjusted feedrate should be 31 inches per ...
P: About Contact Search Learn the pros and cons of low helix, high helix and variable helix angles and how they impact your machining and workpiece finish.
On an end mill with a 30 degree helix angle, 25 % of the force is axial and 75 % radial. On a 45 deg. helix angle, the forces are divided equally, 50 % radial and 50 % axial. High helix cutters have an helix angle of 60 deg. At a higher helix angle the radial forces are lower and cutting is smoother, vibrations lower.
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.
The choice of helix angle: for difficulttocut materials with low thermal conductivity of stainless steel and greater heat impact on the cutting edge, a large helix angle end mill is used for cutting, which helps to extend the life of the tool. In addition, the characteristics of the finished surface change due to the helix angle.
