Aluminium cutting

[EddyCurrent]

Hi Bush flyer,

I recently cut some elongated slots with a 3mm carbide bit without any problems.

What's the cutter details ? e.g. single flute, up spiral

Edit: This might seem a daft question but to me the thread is going round in a circle until Bush Flyer uses a cutter of the same type and most importantly, brand, that others are using when they suggest cutting parameters. The difference between a good cutter and a bad one is chalk and cheese.
