Carbide tipped bits fit in a heavy duty metal bit board designed for heavy duty use and long wear life.  They are commonly used on Balderson mounted front groomers for motor graders and can also be put on the moldboard of motor graders.

There are different styles and shapes of the carbide bits.  The Cat style triangle bits are very long lasting and larger than the conical or rotating style.  They are held in place with a snap ring.  This cat style does not rotate and they tend to require zero maintenance compared to the rotating conical bits.  The Cat style carbide bits also are more aggressive and can dig deeper.

The other common style of conical bits or rotating bits are Kenemetal style or Sandvic style.  These are mounted with a internal ring that keeps them secure and help with allowing the rotation of the bit.
