Thanks Br,
I've done a bit of NPT thread milling in aluminum with an insert cutter, and liked it a lot. I just don't have big enough arms to turn a 2" pipe tap
I am much more nervous about milling smaller holes in steel, though. This means I have to buy the solid carbide thread mills, and I am worried about recutting chips and spoiling the tool. There is not a lot of room around the tool in these situations.
When I look at paying $300 Cdn for one to experiment with, I just know the first one is going to last about 2 seconds
Do you use an air blast to remove the chips?
I assume these are best used dry?
I also assume climb cutting is best?
