End Mill Flutes - What Are They, and How Many Do I need?
The Spiral-shaped cutting edges on the side of the end mill are called flutes.
Flutes provide an empty path for the cutting chips to escape from when the end mill is rotating in a workpiece.
End Mills have either 2, 3 or 4 flutes per bit. 2 and 4 flutes are the most popular.
2 Flute End Mills (Slot drills):
For use on wood and aluminium
Fewer flutes are best for chip evacuation, keeping the bit cooler, but leaving a rougher surface cut.
2 flutes are best for use on Wood and aluminium as these produce very large chips in comparison to other materials.
2 flute end mills are also referred to as slot drills.
2 flute end mills for cutting slots, profiling, routing, plunge cutting on aluminium and wood
4 Flute End Mills:
For use on most other materials
4 flutes are used on most other materials, can cut harder materials than 2 flutes and will create an overall smoother surface finish.



HSS550TC end mill cutters are made of M42 HSS,which is with low vanadium content (around 1%) and high cobalt content (≤8%). This series of cutters are normally used for hard-cut materials, such as ordinary medium and low carbon steel, alloy steel and other materials processing.
