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 dental laboratory protocols, though service life depends on application and material hardness.

The flame head tapers from a full body to a fine point, for interdental areas, embrasures and blending contours on acrylic and frameworks. At 6.0 mm the head is one of the largest in the range, for bulk reduction of denture bases and large acrylic blocks. Its XA-cut (left-twisted crosscut) clears chips and runs without snagging.
