2 Flute 45° Helix Square End Mills for CNC Milling

2 flute 45° helix square end mills are designed for CNC milling applications that benefit from improved chip evacuation and smoother cutting action. The higher helix angle helps direct chips away from the cutting zone while reducing cutting forces, making these tools well suited for aluminum, non-ferrous materials, plastics, and other free-machining materials.

 

The two-flute geometry provides large flute valleys for efficient chip removal during slotting, profiling, pocketing, and contouring operations. Combined with the 45° helix design, these end mills help promote cleaner cuts, improved surface finishes, and stable machining performance.

 

The square end geometry produces flat-bottom features and sharp internal corners, making these tools a versatile choice for a wide range of CNC milling applications. Use the filters below to select the desired diameter, length of cut, reach, coating, shank size, or overall length for your machining requirements.
