7 Best Router Bits for Sign Making Reviews

After considerable research, analysis, and discussion, we have selected the seven following router bits for you based on performance, durability, and compatibility with different types of routers and projects.

1. Amana Tool AMS-177-K 8-Pc CNC Router Bit – Best Pick

Today’s first pick is a wildly popular offering from Amana Tools, a brand that has rightly earned its high reputation in nearly a century of successful operation. This 8-piece CNC router bit set is well suited to the needs of the beginner, novice, or expert.

Furnished with a beautiful multi-colored Spektra coating, this collection is one of the most durable we’ve found, thanks to high-quality carbide tips. Spektra is an ultra-light ceramic coating that facilitates the bits in maintaining their sharpness and smoothness.

What’s more, the Spektra coating also works against oxidization and high heat production, which, as you may already know, affects the bits’ cutting quality.

This set comes with every kind of bit you might need for your sign making purposes, with each bit having a quarter-inch diameter.

You can use these bits on a wide variety of work materials, from plastic, fiberglass, graphite, and wood to even Plexiglas and PVC, among others. So, no matter the style and intensity of your project, these bits won’t let you down.

Although the beautiful Spektra coating will lose its vivid coloring over time, it will still retain its protective quality, so don’t worry. With such high-quality construction and unique geometric design, these are easily some of the absolute best bits you can find to use with your CNC router.

Pros

  • Extra strong construction with highly durable Carbide tips

No matter the quality and efficiency of your particular CNC machine, these bits promise to provide a long cutting life and smooth finishes every time.

Part of this owes itself to the V-groove design of these bits, manifested in a steep taper that will help you produce deep, sharp grooves. For deep grooves with softly rounded bottoms, the ball-nose bits are ideal, while the up-and-down spiral bits are ideal for making clean, swift cuts.

What truly makes a router bit set great is its compatibility with different materials. Well, on that front, Freud surely does not disappoint. Designed for smooth and reliable usage, these bits can be used on wood composite, wood, aluminum, and plastic, among other materials.

What to Look for Before Buying A Router Bit for Sign Making?

Lettering and routing is one of the most intricate types of woodworking to exist. So before you choose the right bit, remember to keep the following factors in mind.

Bit Construction

The performance of a router bit depends greatly on its construction and strength. We would recommend selecting a bit that comes with a carbide tip because this construction material allows the user to make smooth and precise cuts.

What’s more, carbide-tipped bits are more durable than those that aren’t. The more longevity a bit’s tip boasts, the less frequently you will have to re-grind or replace it.

Compatibility

Although this goes without saying, it’s good to have a reminder: your chosen router bits must obviously be compatible with your particular router. How can you ensure that? Check the shank of the bit – the solid cylindrical part of it. This shank must be compatible with your router’s collet for good performance.

Do you have a router with interchangeable collets? Even better! A half- or quarter-inch shank works best in this case, especially if you’ll be doing freehand lettering. That’s because shanks of this diameter offer lower vibration and, consequently, higher stability. You can expect a smoother cut from such bits.

Work Material

Not all projects are the same; each one requires a different sort of router bit. You know your project best, but remember to keep in mind what material you’ll be working with. Not every bit is compatible with every kind of woodworking need, so look carefully into the manufacturer’s instructions before buying.

Router Bit Set

Are you a beginner in routing? Or don’t have a particular project in mind? Then you might be better off buying a set of bits rather than an individual type. This will allow you to experiment and find the right bit for your needs.

That being said, watch out for sets that are cheap; the bits in these tend to be more fragile to keep the price low. However, if you’re only experimenting at this stage, that shouldn’t be too much of an issue if you can afford to replace them frequently.

Anti-Kickback Design

Kickback is one of the worst nightmares of any DIYer, especially when it comes to lettering and sign-making. Keeping that in mind, it’s always a good idea to buy bits that are advertised as having an anti-kickback design, as these have higher girth and don’t bite too deeply into your workpiece.

Methods to Make Sign

Manual Method

Although today we’re discussing bits for machine-based sign-making, you can also opt to make signs and lettering with your bare hands.: called freehand routing. It might seem unnecessary, especially if you’re a beginner.

However, many experienced woodworkers prefer the manual method if they want to feel closer to the process of sign- or letter-making.

Particularly if you’ll be creating intricate shapes and designs, or small letters, the manual method will suit your needs well. That’s because you’ll be allowed to enjoy a certain level of precision not found in machine-assisted methods.

CNC-Assisted Method

If you’re used to doing CNC (Computer Numeric Control) routing, you’ll be glad to hear that you can use it to make signs and lettering. Not only is it faster thanks to being automated, but it also offers higher precision. However, the quality of the work also depends on your level of expertise.

One great advantage of CNC routing is that it allows you to work with a number of different materials, be it plastic, aluminum, steel, composite, or even glass. That being said, if you’re interested in CNC routing, be prepared to shell out a good amount of money!

Frequently Asked Questions

What router bit do I need for sign making?

The answer to this question depends on your needs and what kind of project you’re undertaking. That being said, the majority of professionals like to use V-groove and carving bits or those with round noses.

What is the point of a V-groove on a router bit?

What makes V-groove bits special is their ability to produce square corners. That makes them ideal for creating signs and lettering.

Can CNC bits be used in a router?

Yes. CNC bits are best used in high-load routing situations thanks to their ability to remove material at a high rate. However, it does require some practice, so we would not recommend it for beginners.

Should I buy a straight bit or a spiral bit?

We would suggest going for a spiral bit if you’re working with hardwoods or smooth surfaces. Straight bits are better suited to working with stock.

Final Words

When it comes to choosing the best router bits for sign making, much depends upon your intended use, the quality of your router, and the work material you will be working with.

That being said, although we don’t like to pick favorites, this 8-piece set from Amana is a clear winner for all kinds of lettering and sign-making applications. It’s built for long life, smooth performance, and versatility.

On a budget? Not to worry! This 4-piece offering from FOOS offers impressive performance and durability at a nearly unbelievable price, and it’s even compatible with various work materials.

Good luck, and happy routing!
