Do I Really Need to Hone My Router Bit Face after Sharpening for Best Results?

Many woodworkers wonder if it’s necessary to hone their router bit face after sharpening. The answer is a resounding yes! Honing your router bit face is a crucial step that ensures a precise and burr-free cut.

Why Hone Your Router Bit Face?

  • A sharp router bit is meaningless without a honed edge. Sharpening alone won’t remove the microscopic ridges and burs that can cause uneven cuts, tear out, and poor finishes.
  • Honing helps to:
    • Remove metal smearing, which can lead to poor contact and vibration during routing
    • Reduce friction, making it easier to push the bit through the material
    • Prevent chip-out, a common issue when cutting abrasive materials

How to Hone Your Router Bit Face

  1. Choose the right honing stone : Opt for a fine-grit diamond stone (120-150 grit) or a ceramic stone (180-220 grit) specifically designed for honing router bit edges.
  2. Position the stone : Place the honing stone flat on a stable surface, with the fine grit surface facing up. Hold the router bit at a 23-degree angle, similar to sharpening.
  3. Make light passes : Slowly move the router bit over the honing stone, applying light pressure. Repeat this process 5-7 times, or until the bit starts to “sing” as it glides across the stone.
  4. Check the edge : Inspect the edge of the router bit. It should be free of metal smearing and have a clean, even finish.

Tips and Tricks

  • Always hone in one direction only, following the edge of the router bit.
  • Use a light touch, as excessive pressure can damage the bit or stone.
  • Regular honing helps maintain the edge’s performance and prevents the buildup of metal residue.
