Wood router bit types fall into a handful of families, and each one is designed for a specific cut: straight grooves, edge profiles, joinery, or trimming. This guide explains the main types, what each does best, and how to pick the right one before you clamp a board into the router table. By the end, you will know which bit matches your project and how to set it up safely.

Know the Main Families of Router Bits

Most router bits for wood sort into a few core families. Straight bits cut flat-bottomed grooves and dadoes. Round-over bits soften edges with a convex curve. Chamfer bits cut a flat 45-degree (or other angle) bevel. Rabbeting bits cut a stepped recess along an edge, often for a back panel or a lid. Each family does one job well, so start by identifying the cut you need.

Match Profile Bits to Edge and Joinery Work

Profile bits shape the edge of a board. A cove bit cuts a concave curve, a beading bit adds a decorative bead, and an ogee bit creates an S-shaped profile common on tabletops and picture frames. Joinery bits include dovetail bits, which cut the interlocking pins and tails used in drawer boxes, and lock miter bits for tight corner joints. Joinery bits usually require a fixed template or precise depth setting, so make test cuts on scrap first.

Choose Trim and Flush Bits for Panels and Templates

Flush trim bits have a guide bearing at the tip or shank, so the bit follows a template or the edge of a previous cut. They are the go-to choice for trimming laminate or veneer flush to a substrate, and for copying a shape using a template. Pattern bits work on the same principle and are typically used with a template for repeat parts. Keep the bearing clean and check that it rolls freely before every job.

Quick Reference for Common Bit Types

Bit type Typical cut Common use
Straight Flat-bottomed groove Dadoes, shelf slots
Round-over Convex edge curve Softening table edges
Chamfer Flat angled bevel Decorative edges, layout marks
Rabbeting Stepped recess Back panels, lids
Cove and ogee Concave or S-curve profile Trim, moldings
Dovetail Angled interlocking cut Drawer joinery
Flush trim Trims to a guide edge Template work, laminate trimming

Checklist Before You Buy or Use a Bit

  1. Identify the cut: groove, edge profile, joint, or trim.
  2. Confirm the shank size matches your router collet (commonly 1/4 inch or 1/2 inch).
  3. Check the cutting depth against the thickness of your stock.
  4. Decide whether you need a guide bearing for template or edge work.
  5. Make a test cut on scrap wood of the same species and thickness.

Common Mistakes

  • Taking too deep a pass in one go. Remove material in two or three shallow passes.
  • Routing against the rotation of the bit, which causes kickback. Feed from the correct direction.
  • Ignoring a dull or chipped bit, which burns the wood and strains the motor.
  • Mixing shank sizes or using a worn collet, which lets the bit wobble.
  • Skipping test cuts when setting depth or bearing alignment.
  • A bit set with a case keeps common profiles organized and easy to reach. View on Amazon
  • A router table with a fence makes edge profiling safer and more consistent. View on Amazon
  • A collet wrench and a clean collet help the bit stay centered at speed. View on Amazon

FAQ

What is the most useful router bit for a beginner?

A straight bit is the most versatile starting point, since it cuts dadoes, grooves and slots. A round-over bit is a close second for softening edges.

Do I need a 1/4 inch or 1/2 inch shank?

Match the shank to your router’s collet size, which is printed in the router manual. Larger 1/2 inch shanks generally vibrate less at high depths.

How do I know if a bit is worn out?

Signs include burn marks, rough or fuzzy cuts, and more effort needed to feed the wood. Replace or resharpen the bit when you see these signs.

Conclusion

Wood router bit types are easiest to choose when you start with the cut you need: grooves, edge profiles, joinery or trimming. Match the shank and cutting depth to your router, then test on scrap before committing to a project piece. Work through the basics first, and you will build confidence for more complex profiles.
