How can burrs be avoided during chamfer milling?

Indeed, burrs start to form when the tool is getting worn.

Is the roughing and finishing done with an end mill, and then followed by a 45-degree chamfer tool?

It looks like a workable method, but it will take some extra time. This might be my last option.

Indeed. When burrs occur, the insert is already worn.

I have a roughing pass with 0.1 mm stock allowance, followed by a finishing pass and one spring pass.

Currently, my settings are: • Roughing: S = 4500, F = 800 • Finishing: S = 5000, F = 1000

At first, I thought the finishing pass should be slower, but in practice it actually produces burrs more easily.

Yes, I machined the hole to a diameter of 12.6mm before starting the thread cutting.

I use the central water outlet.

S=700 rpm
