The chip out of some CNC router bits was annoying, so i ordered some different types and made this test.
The candidates:
1.) straight cut router bit
2.) up cut router bit
3.) down cut router bit
4.) up/down cut router bit
Like standard router bits for handheld machines, the straight cut type seems to work great on my CNC.
All four router bits are from aliexpress-Seller “CNC Cheap Store”:
