What is flute length on an end mill?
22mm
Flute length: 22mm. Helix angle: 45°
How do you choose an end mill size?
The length of cut needed for any end mill should be dictated by the longest contact length during an operation. This should be only as long as needed, and no longer. Selecting the shortest tool possible will result in minimized overhang, a more rigid setup, and reduced chatter.
Can you use a drill bit as an end mill?
A drill bit is designed to bore straight down into the material – metal, plastic, or wood – whereas an end mill is designed for sideways cutting. The two cannot be interchanged.
What gives a better surface finish 2 flute or 4 flute end mills?

What is flute count?
Simply put, flutes are the part of the anatomy that allows the end mill to cut on its edge. One consideration that must be made during tool selection is flute count, something we have previously covered in depth. Generally, the lower the flute count, the larger the flute valley – the empty space between cutting edges.

What type of end mill is recommended for cutting aluminum?

Flutes don’t come in different ‘sizes’ as such, but you can get curved headjoints for a small beginner. This brings the keys of the flute closer to the body, reducing the stretch.
How are flute holes measured?
Finger Hole Location
Measure the total physical length of the bore of the flute: the distance from the bottom end of the plug to the open foot end of the flute. Then divide this in half and mark a “midway” point on the body of the flute.
Are more flutes better?
In a more traditional sense, higher flute counts are great for finishing operations where very small amounts of material are being removed, and greater finish can be achieved with more flutes, not worrying as much about chip evacuation. Flute count plays a big role in speeds and feeds calculation as well.
