When looking for cutters there are an awful ot of combinations not just of HSS, Carbide or coated but also a lot of choce in Helix angle, Grain size of material , number of flutes and HRC (hardness) Anyone out there techie enough to give the pros and cons of these latter options. Especially regarding wooden and composite wood materials.
