Dear all,

When I do circular milling operations with small end mills, chips tend to weld to the endmill until it breaks. It happens even if a drill a pre-hole before using the end mill to make it bigger.
I solved this issue using coolant fluid, but I would prefer to avoid the coolant.
Do you have any advice?
For your information I use uncoated 2 fluts 4 mm end mill at 24000 rpm with 2mm WOC and 0.4 mm DOC
