Frequently Asked Questions

Introduction: Planning to cut plywood with a router? Here are some commonly asked questions and their answers to help you choose the right router bit.

1. What kind of router bit should I use to cut plywood?

When cutting plywood with a router, it’s best to use a straight bit or a spiral upcut bit. These bits are designed to efficiently remove material while minimizing tear-out and achieving clean, smooth cuts. Straight bits are great for general cutting tasks, while spiral upcut bits are specifically designed for excellent chip evacuation, reducing the chance of clogging.

Both types of router bits come in various sizes, so choosing the right diameter will depend on the thickness of your plywood. If you’re cutting through-thickness, consider using a longer bit to accommodate the material’s depth. Ultimately, the key is to select a router bit that is sharp, suitable for plywood, and compatible with your router.

2. Can I use a router bit meant for other materials to cut plywood?

While it might be tempting to use a router bit meant for other materials, it’s generally not recommended. Plywood has unique properties, including layers of thin veneer and an adhesive core. Using a router bit specifically designed for plywood ensures cleaner cuts and reduces the risk of tear-out or splintering.

Bits for plywood are typically designed with a higher number of flutes, allowing for better chip evacuation and improved cutting efficiency. These bits also tend to have a sharper cutting edge, perfect for accurately cutting through the layers of plywood. So, it’s best to invest in a router bit that is specifically designed for cutting plywood.

3. What is the difference between a straight bit and a spiral upcut bit for cutting plywood?

The primary difference between a straight bit and a spiral upcut bit lies in their cutting actions. A straight bit has a flat bottom and cuts straight down, making it ideal for cutting dados or creating straight edges in plywood. On the other hand, a spiral upcut bit has flutes that spiral upward, helping to clear away debris and prevent clogging.

Straight bits are more versatile and can be used for various cutting tasks. However, when precision and chip evacuation are important, a spiral upcut bit is your best bet. Spiral upcut bits create cleaner cuts, reduce tear-out, and are particularly effective when cutting plywood with delicate surfaces or veneers.

4. What is the best router speed to cut plywood?

The optimal router speed for cutting plywood depends on various factors, including the type of router bit and the thickness of the plywood. As a general guideline, it’s recommended to start at a lower speed and increase it gradually until you find the right balance of cutting efficiency and control.

If you’re using a large diameter router bit, a slower speed is typically advised to prevent overheating and ensure smoother cuts. Smaller diameter bits can handle higher speeds. Additionally, lower router speeds are advantageous when working with thinner plywood, as they minimize the risk of tear-out or chipping.

5. How can I minimize tear-out when cutting plywood with a router?

Tear-out can be a frustrating issue when cutting plywood with a router, but there are strategies to reduce it. First, ensure that you’re using a sharp router bit specifically designed for plywood. Dull bits can lead to ragged edges and tear-out.

Another technique is to score the cut line with a utility knife before using the router. This pre-cuts the top veneer, preventing it from splintering. Additionally, using a sacrificial backing board underneath the plywood can help support the wood fibers and reduce tear-out. Finally, adjusting the router speed and making multiple shallow passes can also minimize tear-out by gradually removing material and reducing the strain on the wood fibers.
