Reply To: End Mill Sharpening

[Stewart HartParticipant @stewarthart90345]

Hi

Don't get mixed up with slot drills and end mills:- slot drills you can plunge cut and usually have two or three flutes, end mills are for cutting horizontally, the four flute jobs that cut across centre are a bit of a mix between the two personally I wouldn't use them as a slot drill

I've reground all these cutters the two on the left are slot drills the four flute on the right is milling cutter, the two slot drill I re-cut the gash with a hand held dremell I gashed the end mill on my home brew cutter grinder you can see I've reground it quite a few times and the original centre hole has gone.

This is how I gashed it

And sharpended the face

And proof of the pudding EN8 milled on my X3
