The tooth profile is carefully manufactured using a synchronised CNC process giving a super sharp clean cut tooth profile. The tooth profile has really good grip, and doesn't build up plastic debris.
These hobbed pulleys are well suited for 1.75mm filament with a 5mm shaft They have been tested, and performed well, on flexible filaments and abrasive filaments.
These can be used in a similar way to a hobbed bolt, but these are much more precise, and are threaded on the both ends, so they can be easily adjusted.
