Bits / Workshop reference

Flush-trim & bearing-guided bits

Copy a template or bring an edge flush while keeping the bearing on a reliable reference.

How it works

The bearing follows an existing edge or template while the cutting edge trims adjacent material. Bearing location determines where the template must sit.

When to consider it

Use a compatible bearing-guided tool for template work with sufficient stock support and the correct top- or bottom-bearing arrangement.

Where it does not apply

A bearing is a guide, not a clamp. Do not let it run off the template or use a damaged, loose or seized bearing.

Side-view concept: the bearing follows the template above the workpiece. Top- and bottom-bearing setups differ. Concept diagram, not to scale; guards and fixtures are omitted.

Before the first cut

  1. With power isolated, verify the bearing and retaining hardware per the tool instructions.
  2. Secure the template and workpiece; check bearing contact and cutter clearance along the entire edge.
  3. Use the router manual's feed-direction guidance. Do not transfer CNC climb-cut strategies to handheld routing.

If the result looks wrong

Stop the machine and make it safe to inspect before checking the tool or workpiece.

Template shape is copied poorly

Check template quality, bearing contact, workpiece movement and the bearing/cutter diameter relationship.

Chatter or grabbing

Stop and review support, excess stock and feed direction with the equipment guidance.

Use the matching calculator

Calculator outputs describe geometry, time or cost—not permission to operate at those values.

Make the setup repeatable

In Machine & Bit Settings, keep these details in the standard fields, additional fields and setup notes. Record a test date only after testing that exact setup.

  • Bearing position and diameter
  • Template thickness
  • Routing arrangement and stock allowance

No cutting settings are automatically supplied or saved by this guide.
