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 results of experimental research on the influence of the helix angle on high performance milling of AlZn5.5MgCu alloy are presented. End mills with a wavy shape of a cutting edge, dedicated to rough high performance machining, were used. The helix angle was changed in the range of 20° to 50° with a step of 5°. During the milling tests, three cutting force components were measured. After ...

Features of end mill helix angle. The larger the helix angle of the end mill, the longer the contact length between the workpiece and the cutting edge. This can reduce the load on the cutting edge per unit length, so it can prolong the tool life. However, at the same time, the cutting resistance will become larger, so the tool holder with high ...

Helix angle. The helix angle is the angle that an end mill's helical cutting edge makes with the plane of its centreline. On the periphery, the helix angle is the axial rake angle of the peripheral cutting edges. A higher helix angle means a larger rake angle, thereby increasing sharpness to the tool. - Click below to read more!
