Fixed-Base Router

A fixed-base router has a set cutting depth, which must be determined before you start routing. This makes it more stable and easier to control for edge work or cutting grooves and slots. Fixed-base routers are preferred for tasks that require precise, shallow cuts like edge profiling or dado cutting.

Best for: Precise, shallow cuts such as grooves and edge work.
Advantages: Stable, easier to control for beginners.
Drawbacks: Lacks the flexibility of plunge routers for adjusting depth mid-cut.

Trim (Palm) Router

A trim router (or palm router) is smaller and lighter than full-size routers. These compact tools are perfect for light-duty tasks, such as trimming laminate, rounding edges, or fine detail work. While they aren’t powerful enough for heavy-duty projects, their portability and ease of use make them ideal for small, precise jobs.

Best for: Trimming, edge rounding, and detailed work.
Advantages: Lightweight, easy to handle, good for small projects.
Drawbacks: Not suitable for large or deep cuts.

Combo Router Kit

A combo router kit includes both a fixed base and a plunge base in a single package, allowing users to switch between the two based on the project’s requirements. This makes combo kits versatile and cost-effective for those who need both functionalities without purchasing separate routers.

Best for: Those who need both fixed and plunge capabilities.
Advantages: Versatile, cost-effective.
Drawbacks: Bulkier and may be more complex for beginners.

CNC Router

A CNC (Computer Numerical Control) router is a computer-controlled cutting machine. CNC routers are highly precise and can automate intricate and repetitive tasks like engraving, 3D carving, and cutting custom parts. While primarily used in professional or commercial settings, CNC routers are becoming more accessible to hobbyists as well.

Best for: Precision cutting, 3D carving, and mass production.
Advantages: Extremely accurate and precise.
Drawbacks: Expensive, requires programming knowledge.

Router Applications

Routers can perform a wide variety of tasks in woodworking, making them essential for different projects. Here are some of the key applications:

Edge Profiling

Edge profiling refers to shaping the edges of a workpiece to add decorative or functional features. With various router bits, you can create rounded edges, chamfers, ogee patterns, and more. This is especially useful in furniture making, where finely shaped edges add aesthetic appeal.

Joint Cutting

Woodworking routers are frequently used to cut strong, precise joints. Routers can create dovetail, mortise and tenon, box joints, and dadoes, which are essential for constructing sturdy furniture and cabinetry.

Decorative Inlays and Engraving

Routers are also used for creating inlays—small, intricate pieces of wood or other materials set into a larger surface to form decorative designs. Additionally, with the right bit, routers can be used for engraving patterns, letters, or other details on wood surfaces.

Hollowing and Trimming

Routers are excellent for hollowing out sections of wood, whether for creating recesses for hardware or for thinning down a piece. They can also be used for trimming excess material, providing a smooth and even finish to projects like cabinets, tabletops, or veneer work.

Understanding Router Bits

The router’s versatility is largely due to the wide range of bits available, each designed for specific tasks. Common types of router bits include:

Straight bits: Used for cutting straight grooves, dadoes, and hollowing.
Rabbeting bits: Designed to cut a shoulder or rabbet on the edge of a workpiece.
Flush-trim bits: These bits are ideal for trimming laminate or veneer to match the underlying surface.
Roundover bits: Used to create smooth, rounded edges on wood pieces.
Chamfer bits: Perfect for cutting bevels along the edges of a workpiece.
Molding bits: These bits are used for more elaborate designs and edge detailing.
Specialty bits: Designed for specific, intricate tasks like dovetail joints or letter engraving.

Router Bit Speed and Feed Rate

For optimal performance, you need to match the bit speed and feed rate to the size of the bit and the type of material you're working with. The speed at which your router spins (RPM) and the speed at which you feed the router into the wood play a critical role in the quality of the cut. Too fast, and you risk burning the wood; too slow, and the cut can become rough and imprecise.

Small bits (1” or less): Higher speeds (20,000-25,000 RPM) are optimal for smaller bits to prevent stalling.
Larger bits (1” or more): Lower speeds (10,000-15,000 RPM) are best to avoid overheating and burning.

As for feed rate, this refers to how fast you move the router along the material. The ideal feed rate will depend on the bit size, material density, and desired finish. Moving too fast can cause rough, uneven cuts, while moving too slowly can overheat the bit.

Router Safety Tips and Best Practices

Working with a router requires care and attention to detail. Follow these safety tips to ensure a safe woodworking experience:

Wear protective gear: Always wear safety glasses, hearing protection, and a dust mask when working with a router. Routers can be noisy, and wood chips and dust can be harmful.
Secure the workpiece: Ensure your wood is properly clamped to your workbench or table before routing.
Check the bit: Always ensure that the router bit is securely fastened in the collet and that the collet itself is tightened.
Set the depth carefully: Make small, shallow passes rather than trying to cut too deep in one go. This reduces strain on the router and produces a cleaner result.
Use a guide: If you're making long, straight cuts, use a guide or a straight edge to ensure accuracy.
Move against the bit rotation: When routing along the edge, always move the router against the direction of bit rotation to prevent kickback.
