45° for general work
The 45° blade is the general purpose angle. The V-B3 box holds three cemented carbide 45° blades, and V-B5S holds five easy-turn 45° blades.
30° for thin film and fine detail
V-B5/30 carries five 30° shaper-tip blades for standard vinyl and thin film with fine curves. V-B3S/30 is an extra-sharp coated tungsten carbide 30° blade with a 2mm cutting depth for tough material and film.
60° for thicker material
V-B5/60 holds five 60° blades with a flattened tip, for demanding vinyl work. Sign makers usually reach for a 60° blade when the material is thicker than normal sign vinyl, so test it on an offcut first.
A mixed box
V-B5 mixes three 45°, one 30° and one 60° blade, which is the easiest way to try each angle on your own material. V-Auto cutters ship with five blades in that mix.
