Make shallow incisions in fabric, leather, and rubber. Unlike other router bits, these bits do not spin or rotate; instead, the blade follows the motion of the CNC machine, behaving like a rudder as it cuts through material. These bits are plunge cutting, letting you cut directly into the workpiece from above.

Carbide bits have a small, sharp point for cutting precise, thin lines. They’re spring loaded to apply constant pressure to the tip, making them good for cutting thinner materials than steel bits.

Steel bits use a utility-knife blade; the larger blade cuts through thicker materials than carbide bits.
