Most jointers feature a cutter head equipped with two or three blades, though some newer models offer four. The specific number depends on the make and model. Three-blade cutter heads are typically the standard in modern machines. However, many woodworkers now prefer cutter heads with carbide inserts, which deliver superior cuts and a cleaner finish. If a traditional jointer blade gets nicked, you must replace or rotate the entire blade, whereas with carbide insert jointers, you can simply rotate the damaged insert to a fresh edge, extending the tool's life and minimizing downtime.
