Doesanyone know of somewhere I can send my end mills to to get sharpened or am I just better off buying new?

Probably not worth it for smaller sizes 6mm and below. Might break even 8-10mm . Larger sizes you may save money over buying new.

JB, Is that just for HSS or are you including solid carbide in your response?

As Jason has said small ones , not worth the effort. Bigger ones, possibly. Someone with a Clarkson T&C grinder may be able to help you for a few beer tokens ? Noel.

Beer tokens sounds good to me

I can get carbide for the same sort of money FC-3 disposable HSS sells for so to me not worth it for either. Have not bought HSS milling cutters for several years now I just get carbide and use that on the manual mill as well as the CNC.

Former work only used to have large diameter, long series end mills sharpened.

Large diameter here being 25mm or larger – anything smaller was more cost effective to buy new (Cutwel usually, occasionally MSC)

When Cromwell had local reps. (before they were taken over) we used to collect up half a dozen or so cutters & the rep took them away to get reground. Turnaround was about a fortnight.

Can’t recall how we got them done after the reps went, but do recall packing them up to be couriered somewhere.They didn’t need doing often, as roughing out was done with inserted cutters & the long HSS end mills were only used for full depth finishing passes where a good finish was required.
