Everyone is welcome to bring some but going to have to put a 5-6 ? limit on them so everyone gets a chance.
Will be able to do 3mm to 12mm in 2,3 or 4 flute in HSS or Carbide.
If you have any with chipped ends then just flat them off on a grinder before you come to save having to repeated grind them back. It doesn't need any end cutting edges left, it can start from a solid if needed. 4 flutes can be the type with a pip in or if they are ground back to get rid of the pip then it will grind them centre cutting.
You lads won't be the only ones as there is an article in MEW on the grinder where it's stated that we will be doing cutters at the show.
Article here for those that don't take MEW.
