Key Features & Benefits
- Ball Bearing Guide (TB11) — follows the workpiece edge or template for accurate freehand edge routing, including arched panel door shapes.
- Medium-Scale Classical Profile — the R4.76mm radius gives a well-proportioned traditional moulding suited to standard cabinet rails and stiles up to about 70mm wide.
- Bearing Swappable — fit a TB9 bearing to expose the bottom corner and add a lower bead; TB11 gives the clean single-bead classical profile.
- 2-Flute Carbide-Tipped — long service life across hardwood, softwood, and MDF.
When to Use This Bit
The TTC 12 B suits standard panel door and cabinet moulding work where the workpiece is too curved or irregular for a fence. At 1-1/4″ diameter it handles the medium-scale profile found on most domestic cabinetry. For larger profiles on heavier stock, step up to the TTC 16 B (1/4″ shank) or TTC 12 B 1/2 (1/2″ shank). For fence-only straight-line work, the TTC 12 (no bearing) is a cost-effective alternative.
Pro Tip: When routing panel door arches, clamp a hardboard template to your workpiece and let the bearing ride the template edge — this gives perfectly consistent profiles on every door regardless of the arch shape.
