Milling deep into 6062 T6

Thanks. As regards to a 10mm endmill, having a reduced dia shank, would 9.2mm be about right ? or would it not be reduced enough ?

The YG-1 "extended neck" AluPower cutters have 9.2mm neck for a 10mm cutter. It doesn't need much reduction, as it's simply trying to avoid contact with the previous stepdown.

Here's the ones I got. These are usually £60 here in the UK but I wouldn't ever pay that much. Cutwel do some nice reductions from time to time but I don't recall what I paid. Page 13 of this flier, if the link works:

Nice, I have contacted Rickie Fang for endmills. Any recommendation for boring heads ?. I need something accurate for holes up to 80mm in dia
