Thickness Planers Explained
Transform your lumber with precision and ease.

Thickness planers are essential tools for any woodworking enthusiast looking to achieve smooth, uniform wood surfaces. These machines help you reduce the thickness of boards while ensuring a flat finish. Whether you're working on a DIY project or fine furniture, understanding how to use and choose a thickness planer will elevate your craftsmanship and save you time.
Key highlights
- Achieve uniform thickness
- Reduce rough lumber
- Improve surface finish
- Enhance joinery quality
How to choose (and common mistakes)
This section focuses on milling thickness planers.
Selecting the right thickness planer involves considering several factors. First, think about the type of wood you’ll be working with. A planer with adjustable speed settings can handle different wood species effectively. Next, check the cutter head quality; a helical cutter head provides a smoother finish and reduces tear-out. Many enthusiasts overlook the importance of bed size; a wider bed can support larger boards better. Avoid choosing a model based solely on price; investing in quality pays off in the long run. Lastly, consider portability if you have limited workspace. Take your time to compare features before making a decision.

FAQ
What types of wood can I use with thickness planers?
Thickness planers work well with hardwoods, softwoods, and engineered woods. However, avoid using very dense woods like ebony without ensuring your machine can handle them. Always check the manufacturer's guidelines for specific wood types. Start with softer woods to get a feel for your planer’s capabilities.
How do I maintain my thickness planer?
Regular maintenance includes cleaning the bed and removing dust from the cutter head. Inspect blades for dullness and replace them when necessary. Lubricate moving parts as per the manufacturer's instructions. This will prolong the life of your tool and ensure consistent performance. Set a routine for maintenance to keep your planer in top shape.
What is the difference between a planer and a jointer?
A thickness planer reduces the thickness of wood, while a jointer flattens one face and one edge. Use a jointer first to ensure a flat surface, then run the wood through a thickness planer for uniform thickness. Understanding this difference will help you achieve better results in your woodworking projects.
How can I prevent tear-out when using a thickness planer?
To minimize tear-out, ensure your wood is properly supported and that you are using sharp blades. You can also adjust the feed rate to allow for smoother cutting. Consider using a planer with a helical cutter head, as it reduces tear-out significantly. Always test on scrap wood to find the best settings.
What thickness can I achieve with a thickness planer?
The thickness you can achieve depends on your planer’s specifications. Most planers can reduce wood thickness by up to 1/8 inch per pass. For thicker boards, multiple passes may be necessary. Always refer to the manufacturer's guidelines for maximum thickness capabilities and adjust your approach accordingly.
Is a portable thickness planer worth it?
A portable thickness planer is great for hobbyists or those with limited workspace. They are lightweight and easy to store, yet still deliver excellent results. Just ensure it has the power and features you need for your projects. Test it out with various wood types to see if it meets your expectations.
