Key Features & Benefits
- 25mm cutting diameter — matches standard dado housing, shelf pin strip, and furniture fitting dimensions common in Australian cabinet making.
- Carbide-tipped construction — significantly longer edge life than HSS in abrasive materials such as MDF and particle board.
- 2-flute design — balanced cut for smooth groove walls and accurate shoulders on rebates and housings.
- 1/2″ shank — maximises rigidity and reduces vibration, especially important at the wider cutting diameter of 25mm.
When to Use This Bit
Choose the T 1425 M for general grooving, rebating, and dado housing in timber panels and sheet goods. This is a standard-geometry straight bit without end-cutting capability — it requires ramp entry or edge access rather than direct plunging into the face of a panel. For plunge applications, see the R510 end-cutting series. The R509 series spans 9mm to 28.58mm diameter; select the size to match your housing or fitting dimension.
Pro Tip: For clean, tear-out-free walls in melamine or veneered particleboard, take a light scoring pass (0.5mm deep) at full speed before routing to full depth. Feed from left to right when routing grooves in the centre of a panel face.
