Factors to Consider When Choosing a Router Bit
-
Material compatibility: Wood-only or epoxy too?
-
Durability: How long before it needs sharpening or replacing?
-
Cutting Diameter: Larger bits cover more area but require stronger routers.
-
Shank Size: Match the bit shank (1/2" recommended) with your router collet.
-
Ease of Maintenance: Are inserts replaceable or must the whole bit be replaced?
How Router Bits Perform on Different Materials
-
Softwoods (Pine, Cedar): Most bits perform well. Speed and finish are priorities.
-
Hardwoods (Oak, Maple): Stronger bits like SpeTool or Amana recommended.
-
Epoxy/Resin Slabs: Insert-style carbide bits are best to resist wear and chipping.
