CNC Router Aluminium surfacing

Thank you. Thats the issue i am having. Very limited collet size. Ive used a standard endmill before but i seem to get tooling marks that have a slight texture to them. not sure if this is machine related or if its normal.

Close your eyes and feel the surface with the tip of your finger or the nail of your index finger. If you can feel the pattern then it is machine related and not good. Otherwise it is normal. There is always a visible pattern unless you polish the surface. Of course, you must use sharp tools.
