Best Straight Router Bits AI pick
Chosen by an AI model from its trained knowledge, with its reasoning.
AI pick (line): Freud Double Flute Straight Bits
Freud's double-flute carbide straight bits are consistently sized, sharp and widely available in the dado and rabbet diameters woodworkers actually use.
Not for: Anyone mortising deeply or cutting veneered plywood cleanly, who will get better results from a spiral.
AI picks by need
For undersized dadoes for plywood
Whiteside Plywood Dado (line)
Undersized plywood straight bits match real sheet thickness for snug dadoes.
Not for: Solid-wood or nominal-size joinery where a standard fraction diameter is wanted.
What the AI looks for in Straight Router Bits
- Plunge capability
- Choose a bit with a bottom-cutting edge if you plunge-cut. Bits without bottom cutters burn and stall when plunged.
- Diameter accuracy
- Match diameter to the material: undersized plywood bits for sheet goods, true fractional sizes for solid stock. Plywood is thinner than its nominal size, so standard bits leave loose dadoes.
- Flute count
- Double flute for a smooth finish; single flute for faster feed in soft material and small routers. Fewer flutes clear chips better, while more flutes leave a cleaner wall.
Brands that matter
- Freud: Reliable carbide-tipped straights in wide sizing.
- Whiteside: Premium straights and plywood-specific diameters.
- CMT: Good carbide quality, strong straight-bit range.
- Amana Tool: Industrial-grade straights for heavy use.
What to avoid
- Taking full-depth passes with a wide straight bit in hardwood.
- Buying a nominal 3/4 in bit for 3/4 in plywood dadoes without checking the actual sheet thickness.
