On Small chamfering... Try a SK1S carbide burr...
#0183;#32;I do a lot of small chamfers, and often it is the slowest operation as I am limited to 4 flutes on these 1/4quot; chamfer mills. So, I tried a SK1S carbide burr. It has 16 teeth, and the 45 degree chamfers I am layng down are usually .005 to .010 depth. I was programming .0015 IPT and just a bit rough, but ok.
