Most of the slots are between 6.5 and 8mm wide. The thinking behind drilling the holes is that I get about half of the material cleared before the main slot cut op. It definitely helps, I saw a vid by NYCNC on youtube. Like I say, cycle time isn't really a big issue for me as I'm not making that many parts. I'm really looking for opinions as to how thin a profile cut can be when its made by an end mill. For example, if you were going to cut a 2d profile out of say 15mm thick Al, what's the best cutter to use? I quite often but a square of stock material and have to cut the shape out of it before I even start. Buying laser cut profiles is expensive and normally on a long lead.
