I have a a tool and Die grinder that is supposed to be able to do it. Trouble is, I need another year to recondition it. (I've had it 18 months - I need a round tuit right away!) Second, it does take some skill to use it well.
If anyone has donor broken or really dull HSS end mills that I can buy cheap, then let me know!
Hi Tom O that’s a nice piece of kit you have there. It looks like an air spindle that could be used on a Clarkson Tool & Cutter grinder. It for sure is used to sharpen the flutes of cutters.I was thinking about sharpening endmills a few years ago and bought these.

There is.. Darex makes them.. I have one, but I've never used it.Sooooo….. I take it... there is no such thing as a magical electric pencil sharpener (expensive) out there for end mills. Something some one would invest in and recover the cost for over time eventually turning a profit.
Still, I would like to have my 1", 3/4", 1/2" and 3/8" end mills tuned up. I don't consider the larger ones to be disposable.
Dabbler,
I have some small stuff to donate to your cause. Pretty messed up though. Got a drop box setup somewhere?
I have a book titled MetalWorking from village press. It's a collection of articles from Home Shop Machinist I think. One of the articles is a DIY Tool and Cutter grinder. Major components of the project are the air spindle and the grinder. Since you already have those it might be a very do-able project. I'd loan the book if your interested?I was thinking about sharpening endmills a few years ago and bought these.View attachment 4482View attachment 4483
The shaft is suppose to float on a air cushion and needs the pin that rides in the flute for positioning ( sticking out the front ) then it rocks forward for one of the cuts. I still need to find some collets for it though.View attachment 4484
This is the backside of the grinder with one tray and table off looking at the height-adaptability for a possible marriage of the two. The rotation is reversible.

This is the one I have, but they make other models
Thanks for the package from Falchurch! the 3/8 shank is a handy size to practice with!
