6 Practical Uses for a Router Jig

A router jig is commonly confused with a machine called a “fixture”, which holds a workpiece securely in place while it undergoes a work process. Router jigs do the same thing, but they are also designed to guide the tool that performs the work: a manual router.  

Router jigs are useful for applications that require a workpiece to be secured in place, as a router travels the channels of the jig, shaping the workpiece. The work a router jig can produce depends on the size of the jig and the capabilities of the router. If you have a commercial grade or industrial grade router jig, you can likely use it in the following practical ways, among others.    

1. Cutting Joints

When we hear the word “router”, we often think of woodwork. Routers are used for many types of woodworking procedures, one of the most practical of which is creating joints (a.k.a. joinery). Examples of wood joints router jigs produce include: dovetail, tongue and groove, finger, and mortise and tenon.

If you’re interested in creating woodwork that requires joinery, you can use a router jig to cut the type of joints that provide the best appearance and strength for the type of product you create.  

2. Boring Firearms

Mounting and boring gun components is another practical use for router jigs. For example, there’s a router jig out there for building your own assault rifle (AR) that lets you mount and finish boring the gun’s 80% lower receiver, which houses the gun trigger and the bullet clip.

In addition to being exciting for gun enthusiasts, performing a do-it-yourself gun boring operation costs much less than having a gunsmith do the work. With the right router jig, you can bore lower receivers with the same accuracy and speed as a professional gunshop.   

3. Creating Engravings

Regardless of why you need an engraving, the right router jig can help you apply clear characters and symbols to a variety of materials, including: stone, wood, plastic, and metal.

The materials a router can engrave depends on the power of the equipment and the type of router bit used. Serializing self-built firearms is a good example of how a router jig can perform engraving for a highly practical application. If you build your own firearms, you can use a router jig to apply the serial number.    

4. Finishing Cabinets

Realtors often say bathrooms and kitchens are the two types of rooms in a house that make it appealing to prospective homebuyers. The rooms are quite different, but they often share a similarity: They both have wood cabinets.

In addition to creating precise joints for connecting panels of cabinetry, a router jig can create holes for placing knobs, plant holders, and other types of hardware commonly applied to cabinetry as finishing measures. With the right router bit in place, you can also use a router to apply beveling to cabinetry.          

5. Producing Millwork

Before the invention of routers and milling machines, millwork was done by hand a tedious, painstaking process that could take months or even years to complete, depending on the size of size of the job and the intricacy of the design.

Today, routers make millwork much more efficient, without sacrificing quality. Depending on the capabilities of your router, you can produce highly detailed millwork that looks as if a master woodworker carved it by hand.     

6. Performing Sanding

Some router bits are designed to sand narrow areas, such as the side section of a table top and sides of narrow furniture legs. The length of the router bit contains a coarse surface finish that depending on its material and consistency could be used to sand anything from wood, to stone, to glass.

When using a router jig in this way, it’s highly important to run the router bit at the correct speed (i.e. RPM). Sanding machines commonly have only one speed, but many routers contain variable-frequency drives (VFDs) that let them operate at various speeds. If a router’s RPM is too fast for a sanding bit, the bit could fly apart, the router and the workpiece could be damaged, and the user could be injured.           


Router jigs are often thought of as woodworking machines, and they are. But there’s a lot you can do with a router jig besides woodwork. In addition to using the machine for cutting joints in wood, finishing cabinetry, and producing wooden millwork, you can also use it to bore firearms, create engravings in various materials, and performing sanding.

  1. I feel sad for you for not asking what was that “bullet clip” and “assault rifle” thing that the author wrote about.

  2. your quote ” jig out there for building your own assault rifle (AR) that lets”

    Why are you perpetuating the misnomer that (AR) means Assault Rifle? Shame!
    Just in case you DON’T know…….AR stands for the company that originally created the rifle- Armalite Rifle.

    One of a younger age, might associate a router as a piece of computer network equipment.

  3. a router jig can create holes for placing knobs
    yes it can, but a drill usually works better

  4. @cj
    Sir, I am aware that AR is associated with Armalite, the California based company that has produced the the original M16 rifle. As to associating AR to “assault rifle”, that was totally unintended. Just as I did not want to associate Armando Malite the original inventor of the rifle to the company Armalite. My apologies sir, I I have offended you in any way bu associating AR to assault rifle.

  5. Don’t know who Armondo could be.

    In a very very small nutshell,
    ArmaLite was created in 1954 as a Division of Fairchild Engine and Airplane Corp. as a way of diversification. . Eugene Stoner is considered the creator of the AR (ArmaLite Rifle) . There are (other peoples) thoughts and principles that were derived and combined to create the early iteration of what later became the AR 15/ M16.. An aeronautical engineer and patent attorney George Sullivan had a strong part too.

    As for being “offended”, I find it more Irritating in this generally heated and volatile
    environment, that someone sharing their interest in firearms would perpetuate the
    false association of “AR” as an abbreviation for what is otherwise actually a military-
    fully automatic weapon.

    It’s bad enough linking to the two terms in private conversation, it’s unconscionable in a medium such as this.

    all the best, c
