Buying Guide: Tongue And Groove Router Bits For Plywood
- Shank size: Most plywood projects benefit from a 1/2″ shank for stability and rigidity, especially on thicker stock.
- Cutting diameter and stock thickness: Match the joint depth to your stock in the 1/2″ to 1-1/2″ range; deeper joints need longer cutting length and sturdy hardware.
- Carbide quality: Premium carbide blades (C3 or YG-type carbides) offer longer life and cleaner edges, especially on plywood and laminated panels.
- Anti-kickback design: Vital for safety on plywood surfaces that can pinch or snipe during cutting.
- RPM guidelines: Most sets recommend keeping RPM at or below 18,000 for best results and to minimize burning or tear-out.
- Stock compatibility: Avoid non-wood materials like metal, steel, or sand; these bits are designed for wood, MDF, plywood, and particleboard.
FAQ
- Q: What stock thickness should I use with tongue and groove bits?
- A: Choose bits that fit your stock thickness, typically under 1-1/2″ for most cabinet and panel work; thicker stock may require larger bits or specialized profiles.
- Q: Are larger diameter bits better for plywood?
- A: Larger diameter bits provide stronger joints and faster cutting for large panels but require more robust equipment and proper clearance.
- Q: Can I use non-wood materials with these bits?
- A: No. These bits are designed for wood, plywood, MDF, and similar composites; avoid metal, stone, or non-wood materials.
- Q: What safety practices are recommended?
- A: Clamp stock firmly, follow RPM guidelines, push slowly, and wear eye and hearing protection during use.
- Q: How do I choose between 1/4″ and 1/2″ shanks?
- A: Use 1/4″ shank for light-duty work or smaller machines; 1/2″ shank provides better rigidity for thicker stock and heavier cuts.
- Q: Do these sets include spacers or alignment aids?
- A: Some sets include adjustable spacers; refer to the product features to confirm included components.
