I need to cut a very thin slot in acetal: .079" and I need to cut at least 1" deep. (I actually need a 2" deep slot, but I can do it from both sides.) A 1/16" cutting diameter end mill will generally use a very small shank. Fortunately Sherline makes endmill holders for 1/8" shanks. I just need an unusually long small endmill. I could use a 1/8" cutter also. It just would not be as elegant for this application.
Found a 1/8" shank, 1/8" diameter 1" cutting length endmill. Even better 1/8" shank and diameter. While the cutting length is is only 0.275", the overall length is almost 2", so I should be able to plunge from both sides and do an adequate job.
UPATE: .079"
1/8 (or even 1/16) is a whole lot bigger than the needed 0.0079. Try a wire saw?
ReplyDeleteNot sure how to get a wire saw in some a confined space. I am cutting a T hole.
DeleteYes. Too many 0. 0.079"
