Category Description

2 Flute 30° Helix Square End Mills for CNC Milling

2 flute 30° helix square end mills are designed for slotting, profiling, pocketing, and general-purpose CNC milling applications. The two-flute geometry provides increased flute capacity for chip evacuation, while the 30° helix angle offers a balance of cutting efficiency, edge strength, and machining stability.

 

These solid carbide end mills are commonly used for machining aluminum, steel, stainless steel, cast iron, plastics, and other machinable materials. The square end geometry produces flat-bottom features and sharp internal corners, making these tools suitable for a wide range of milling operations.

 

Use the filters below to select the desired diameter, length of cut, reach, shank size, coating, or overall length for your machining application.
