One bit. Three grit zones. The 5 in 1 Coarse eliminates bit changes during service — straight-cut carbide with Coarse at the base, Medium at the belly, and Fine at the tip for BIAB & hard gel infills and debulking.
Suitable for both left-handed and right-handed use.

The Purple coating features Titanium Aluminium Nitride (TiAlN) properties — a specialist coating engineered for durability and hygiene-conscious techs:
The 5 in 1 Coarse is not designed for heavy bulk removal of harder products like acrylic. Its role is controlled debulking and infill work. Need maximum removal power in the same shape? Step up to the 5 in 1 Extra Coarse. Need less bite? Step down to the 5 in 1 Medium.
