My rockwell horizontal mill has a #30 taper spindle. I recently bought some carbide endmills that do not have a flat on them so they cannot be held with an endmill holder.
I have two ways to hold them. Bison ER32 collet chuck or Erickson 180DA collet chuck. Both suffer from the same limitations. The end of the collet chuck is much larger than the endmill holder so it might hit the vise. Also the nut sticks out farther than the collet so about 1/4 inch of endmill length is lost.
I'm looking for better options. Suggestions please?
BTW, good quality carbide endmills are awesome. I was cutting Stainless steel like it was aluminum! chuck
