Does anyone know where I could find a 5/32 end mill holder for an R8 taper machine? I would like to use one for predrilling 10-32 tapped) holes in some aluminum. Due to the tool changes I will be doing, I would like to try the endmill holders to help preset the length of the tools.
Thanks

ER11 collet holders is probably the best your going to do. Unless you get a 1/8" EM holder and bore it open.

An R-8 collet in 5/32" size is not at all uncommon. You should be able to buy one from just about any industrial supply house. Fair warning though, if you're using a carbide end mill, you'd better get a high-quality collet, such as a Hardinge, to assure minimal runout.
