As a woodworker, you may want to consider investing in a router if you are looking to flatten slabs or make intricate pieces of furniture. They come in a variety of sizes and shapes, and each type has its own strengths and weaknesses.

In this section, we’ll discuss the different types of routers and how they can help you when flattening slabs.

Handheld Routers

They are the most common type of router. As the name implies, these are handheld and capable of moving in any direction. They are best suited for lightweight materials, such as soft woods and plastics but small enough to fit into tight spaces such as cupboard corners or furniture details. They typically feature adjustable cages that can be adjusted for depth stops, allowing for repetitive cuts at specific depths. They require woodworking skills and complete safety is paramount when working with one of these tools.

Table-mounted Routers

They are affixed to the surface of specialized tables or to the underside of standard workshop table saws. This type has variously shaped bases that allow for use with a variety of bits, attachments, and accessories. Many users opt for them because they provide more control and are more readily accessible than their handheld counterparts. Table-mounted models may offer several advantages depending on the needs of the user.

Table-mounted routers offer an amazing amount of control when routing any product allowing users a multitude of possibilities when conducting jobs like flatting slabs that require extreme accuracy when dealing with surface cutting irregular surfaces instead of manually shaping materials one piece at a time over slopes as a most ideal tool this job can handle multiple shaped cuts through wood, plastic or foam shape cuts much needed shaping wooden pieces making repetitive cutting tasks done quickly and properly, flattening slabs and handle large projects individually instead of manually.

Plunge Routers

They are a type that allows you to work on materials such as wood, laminate, and aluminum in situ, or at the location where they will be installed. Rather than carrying the heavy material over to a stationary workshop and cutting it on a large table saw or miter saw, you can use a plunge router to cut joints and rabbets quickly and accurately without having to move the material.

They allow for very precise depth adjustment which makes them ideal for flattening wood and other materials flush with the top surface of an object, tabletop, or work surface quickly and accurately.

Most of them have an adjustable depth stop so you can make repeated cuts at exactly the same depth. This feature is especially useful when performing delicate work such as rabbet joints or shallow mortises where precision is important. The range of router bits available for plunging operations is vast and these accessories can help produce professional results with ease.

Features to Consider

How to Flatten a Live Edge

When choosing the best router for flattening slabs there are several features that should be taken into consideration. Not all of them are created equal so it is important to look for features such as rigidity, durability, power, and accuracy to ensure you get the most out of your router.

Let’s take a look at some of the features you should be considering when choosing a router for flattening slabs.

Motor Power

Motor power is a key feature to consider when shopping for the best router for flattening slabs, as stronger motors will provide more effective cutting performance. This is usually quantified in horsepower (HP). The higher the HP rating of a motor, the more difficult materials, such as hardwoods, can be expected to cut through with ease.

The type of motor also matters and can influence your purchase decision – some routers are equipped with brushless motors while others may have brush-type capabilities. Brushless motors are generally favored because they are larger, faster, and offer higher torque than their brush-type counterparts.

This can translate into less downtime between cuts and a longer overall lifespan for the router making them more energy efficient and cost-effective in the long run. Depending on your budget and how often you plan on using your machine, it’s best to consider both types of motors when choosing your router.

Speed and Torque

It’s important to think about speed and torque. The speed is measured in rotations per minute (RPM). Higher RPM speeds are good for cutting through heavier, harder materials while lower speeds are better suited for softer, lighter materials.

The torque is important because it affects the depth at which you can route. Routers with higher levels of torque will be able to route deeper than routers with lower levels of torque. It’s important to remember that route depth will also be affected by the speed so it’s important to consider both factors in order to find the right results.

In terms of safety, it’s a good idea to look for features such as an electronic brake system, which stops spinning blades quickly in case the operation is stopped suddenly or an electrical overload happens. Some of them also feature an adjustable soft start mechanism, which helps reduce vibration and sound levels when using these machines at higher RPMs. This can provide users with additional flexibility and control when routing or flattening a slab.

Base Plate and Shaft

When choosing the best router for flattening slabs, it’s important to consider the base plate and shaft. The base plate provides stability and accuracy for the router bit operation, while the shape of the shaft influences weight distribution.

The first feature to look for is a solid aluminum baseplate made from cast iron or thick steel. This allows your router to meet even surfaces and ensures accurate cuts over large areas. It should also come with adjustable feet that allow you to easily level your machine at various angles depending on your workpiece. Additionally, an attached lip around the plate helps contain cuttings produced by routing operations.

The shaft is a long rod that connects the handle to the motor housing and bit spindle with ball-bearing guides allowing them to pivot freely in a circular motion around the router’s center of rotation creating a smooth transition when cutting different shapes. Ideally, it has above-average flexibility so you can adjust its angle simply when routing slabs while maintaining balance and weight distribution across both sides of the router during its operation. In short, it should have precision-engineered components such as rubber-fitted bearing plates, an adjustable offset for changing working depths mid-cut, and an ergonomically designed handle for increased comfort and safety during use.

Dust Collection

When it comes to dust collection, there are a few key points to consider that can save you both time and money. The first is the power of the router. With modern routers diverting large volumes of air, you need to ensure your dust collector is powerful enough to match the output. This means considering the watts and amps being used by the router as well as checking for extra features such as anti-clog filters.

The size of your shop floor should also be taken into account when selecting a dust collector. Larger shops may require more than one dust collector in order to optimize efficiency and cost savings. Your preferred method of collecting dust should also be taken into consideration, either via bags or centralized vacuums, which can make all the difference when it comes down to post-processing cleanup.

Think about whether you need additional attachments or add-ons that could come in handy when flattening slabs with a router—vacuum kits, additional hoses, and connectors all make jobs easier and quicker. Last but not least, some of them have their own built-in dust collection systems making them ideal for smaller workshops or those with limited home budgeting options.


When it comes to deciding on the best router for flattening slabs, there are several important accessories that you should take into consideration. Depending on which model you choose, each piece of equipment can help make your job easier and the results more accurate. These accessories include a dust extraction hood, a leg or fence set-up, a circle cutting jig, and other sorts of dedicated jigs for carrying out particular operations on the slab surface or edges.

A dust extraction hood will attach to your table, allowing you to collect any sawdust created as a result of routing operations. This ensures that sawdust does not blow around fire hazards — making your job environment safer — whilst reducing clean-up time when completing projects.

Depending on how often and what type of flat stock you intend to route, investing in a leg or fence set-up might prove useful in creating larger surface area options within the workspace. A circle cutting jig is useful when cutting cutouts or raised circular designs as part of the routed finish — this can also be adapted using other template patterns for creating specialty shapes. Other dedicated jigs could include tenon cutting template sets allowing route faces that require consistently sized recesses with uniform depth across multiple pieces being routed together simultaneously.
