FAQ

What makes a coarse double cut suitable for plastics? The coarse double cut geometry removes material quickly and clears chips efficiently, reducing heat build-up and preventing material from loading the flutes — both critical factors when working with plastics.

What does left-twisted mean on this flame carbide cutter coarse double cut? Left-twisted flutes direct cutting forces and chip evacuation in a specific direction, improving control and surface finish depending on the rotation direction of the handpiece.

Is this a single-use or reusable instrument? Carbide cutters of this type are generally reusable and can be cleaned and sterilized according to standard workshop or laboratory protocols, though service life depends on application and material hardness.
