Those 4 flute bits are probably for metalworking. Typically, the most flutes you'll find on woodworking tooling are 3, and those tools are designed for extremely high feed rates, up to 2000 ipm for 1/2" tools. With small tools, 2 flutes are probably the best bet. Good 3 flute woodworking bits may be an option, if you want to run at very high feedrates.
