Bondtech CHT BiMetal MK8 0.4 mm
The most consistent tip for abrasive filaments
$41
Bondtech’s CHT geometry melts filament faster than a standard tip, so you can keep stock speeds with filled materials while the hardened inserts shrug off carbon fiber. It costs more than generics, but flow consistency showed up in every dimensional check.
