You can use collets or end mill holders to hold end mills. The world is split about 50/50 on which is better. We will give you the arguments for both sides and let you decide.

| Collets | End Mill Holders |
|
Collets are shorter than end mill holders and so give you more vertical work area. |
End mill holders are longer than collets and so let you reach nearer the mini mill's table. |
|
Collets grip the end mill all the way around and so provide a better grip. |
End mill holders have a set screw that bears on the flat on the shank of the end mill and so ensure that the end mill cannot slip. |
|
Collets are more concentric than end mill holders because they grip all the way around the end mill's shank. |
Because they fit the end mill closely end mill holders ensure concentricity. |
|
Collets are less expensive than end mill holders and so can be replaced when they wear out. |
End mill holders are more robust than collets and are less prone to wear out. |
|
It's fun juggling an end mill, a collet and a drawbar all at the same time. |
It is easier to replace an end mill in an end mill holder because the end mill holder can remain in the spindle. |
