Narrow nose bars are good for reducing the chance of kickback while wide nose bars have a much better boring performance. Both of these bars are variations of the solid nose, sprocket nose, and replaceable sprocket nose bar.
Pulling a chain around a larger radius curve reduces friction/resistance, and therefore, heat, wear on the bar, strain on the motor, etc. The larger radius also provides a larger area that you can bore cut with. The downside, is that it also provides a larger area subject to kickback.
A narrow kerf bar and chain is used on the smallest saws. If you use your saw slow and careful, the bar will be fine, but I swing mine like a machete, and the force is sufficient to split and jam the sprocket tip or bend a laminated bar, then they won’t stop throwing chains. “To maintain powerhead rpms, I also use Chisel Skip chains on any bar 24” or larger, kept sharp, and swap them out when they begin to lose their edge.
