COST-EFFECTIVE INSERT BIT
The surfacing router bit utilizes 4-sided solid carbide inserts. All 4 edges of carbide inserts can be used, use a screwdriver to make other blade edge outside. Replace the carbide inserts when needed, instead of replacing the whole bit. Cost effective solution compared to brazed router bits and solid carbide spiral bits.
