Key Features & Benefits
- Double Reed Profile — two matched beads produced in a single pass; ideal for furniture legs, architraves, and cabinet edges that call for a richer decorative profile than a single reed.
- Ball Bearing Guide (TB8) — rides the face of the timber for automatic depth setting; no fence required for edge work.
- Combination Bit Versatility — adjust height to expose just one reed or use at full depth for both; gives multiple profile options from one bit.
- 1/2″ Shank — provides stability and reduced vibration with this wider profile cutter.
When to Use This Bit
Use the TRD 3 B 1/2 when a double-bead decorative edge is required on furniture components, cabinet mouldings, and architraves. Produces a richer profile than the TRS 3 B 1/2 single reed in a single pass. For a four-bead pattern, use TRM 3 B 1/2 (multiple reed).
Pro Tip: The double reed profile creates twice the cutting resistance of a single reed. Use a steady, moderate feed rate and ensure the workpiece is firmly supported to avoid any wobble that would disturb the profile consistency.
