That's odd we are milling all the time at 18K RPM with 200-400ipm with half and 3/4" collets without any problems. (We are cutting wood and MDF.) I have had a lot more problem with 1/4" collets and tools pulling out than with the bigger ones. I have never had a 3/4" tool pull out, half inch in worn collets yes. We are using mostly ER-40 and SYOZ-25 colletted HSK63-F tool holders. You do have to remember that a collet has to be in good condition to work propperly.
----- Original Message ----- ok some valid points yes an end mill holder is a hole with a set screw in it. my night job is supervising 25 people and writing programs. I use very high speed machining techniques . I promise that if you spin an endmill in a collet half inch or larger at 10 k rpm and feed it 2-300 in a min you will find the weakness of the collet and that is it will pull out. I never said a collet was not for milling i advised caution when doing so and to use them for smaller items. I have enough experience in this matter to be certain this is good advice fellas :) -- jeremy youngs ------------------------------------------------------------------------------ Everyone hates slow websites.
