So, the secret to making perfect cut furniture heavily relies on the blades. You see, it is the blades that do the actual cutting. If they are faulty, you’ll certainly not get the best results. So, it’s crucial to have the best biscuit joiner blade to make your woodwork convenient and efficient.

These blades are not for everyone, though- it’s for people who have a workshop already. Oh, if you don’t have the machine yet, then you might want to buy one right away. We’ve compiled a detailed, comprehensive review for the best biscuit joiners to guide you through- check it out.

Biscuit joiner blades come in different sizes and depths. Each blade is made for a specific cut. Thus, you need to consider the work you’re putting the blade into before you buy it.

Indeed, deep cuts will require large blades and the shallow cuts will need you to use small blades. The rule of the thumb is to look for blades that can cut the size of the biscuit.

Fortunately, you do not have to change your biscuit joiner machine every time you get a new blade. The majority of brands offer adjustable sizes for the blades. So, you can change the blade without having to get a new joiner.

Top 5 Best Biscuit Joiner Blade Reviews

So which are the top slate joiner blades that you can buy? Well, I know it is usually a tiresome task to scour the internet or the shelves for a good set of joiner blades. Fortunately, we’ve done the work and compiled a list for you. We’ve picked nothing but the best and included it in our exclusive list of the finest blades for biscuit joiners!

CMT 240.006.04 Biscuit Joiner Blade, 4-Inch Diameter x 6 Teeth, PTFE-Coated

Always look for blades that make your work easy. They need to be sharp and strong. That’s why you should look for one that will fit well in your machine. Your cutter needs to be of high quality in the first place. This is the only way you will make precise cuts. I hope you’ve already had a look at our review.

Then, when you have done that, it’s time to check if your cutting angle makes enough sense. Ideally, you should look for aspects that make your cuts sensible. Remember, this depends on the slate joiner you are using. Also, the kind of furniture you are making will heavily influence the cutting angle that you choose.

CMT 240.006.04 has a 10° ATB teeth and the angle is 18°. The ATB angle means the angle at which the teeth slant. Remember, the blades are simply pieces of metal that that point out of a disk, and they cut into the wood. The angle at which the cogs or teeth slant influences the edge’s effectiveness in slicing through wood or PVC.

But, what if the wood or material being cut is too tough? Let’s talk the truth here- not all materials can be cut by this blade. You certainly don’t want to try ceramics or other hard stuff. However, when you are handling PVC or wood, then you can feel comfortable using high-grade German steel. The teeth have six micro-grain carbide tips that will withstand hardwoods. What this means is that the teeth will not wear out quickly. 

CMT 240.006.04 is metallic- does it mean it will rust and corrode easily? Yes- it will get damaged easily if you allow it to take too long in water or corrosive workshop fluids. But, let’s face it. Do we have a carpenter who can pour water or sulfuric acid on his tools? I don’t think so! Luckily, the blade comes with an orange PFTE industrial coating to ensure that it cannot get corroded. 

Freud FI102 Replacement 4-Inch 8 Tooth Blade For Freud And Other Biscuit Joiners

One of the most fabulous buys you can get is finding strong and sharp blades with a non-corrosive coating. Freud FI102 gives you a taste of the three at an amazingly low price. This is not a tool for every machine though- we need to disclaim this. Instead, it is best used as a replacement for JS100 and JS102 jointer blades. If yours has malfunctioned or has other issues, it is time for you to get a replica.

Of course, I know that nothing makes a wood enthusiast feel betrayed than failing to find a replacement for spoilt parts. It can be depressing. It gets to the point that you even find it necessary to buy another tool altogether. But this shouldn’t always happen. This blade will save you that stress. And, the good thing is that you get to buy an exact match. Of course, they might not be from the same company, but they have been custom made for those two machines.

Then, each piece has eight teeth. The blade can move up to 16000 rpm without getting damaged. Right from its look, you can tell it’s a beast in performance. That’s why you might want to use it quite often. And don’t worry- your warranty is covered by the Freud’s Limited lifetime and Amazon return policies.

Freud FI102 measures four inches and weighs 4.8 ounces. It is lightweight, but that doesn’t mean that it’s any weak. The teeth are tipped with micro-grain carbide which makes it strong enough to cut through wood and PVC without any abrasion.

Yonico 14182q #20 Biscuit Joint Slot Cutter Router Bit 1/4-Inch Shank

For less than twenty bucks, you can get a durable, sharp, and robust joiner blade. Yonico 14182q #20 can cut a slot of 5/32” thick and 1/2 inches deep. It is ideal for size twenty biscuits while the shank is about ¼”.

In our best joiner biscuits review, you might have found out that the cookies you need depend on the size of the hole you make. And, likewise, it all gets down to the blades that your machine have. If they are large, then you’ll need larger biscuits.

I know you could be asking- will my blades’ teeth wear out if I am cutting hard materials? And the answer is simple- yes, if you’re dealing with mahogany!

Most joiner machines are not created for hardwoods. It’s essential to use the tool on softwoods, PVC, or any other similar material. Wood glue will only work if the wood can make seamless pulp with the biscuits. Only the materials that can soak in the adhesive will work well.

Fortunately, though, the Yonico 14182q #20 has a premium C3 micro-grain blade that is made of tungsten carbide to increase sharpness and longevity.

PORTER-CABLE 5558 4-Inch, 6 Tooth Plate Joiner Blade

We’ve already seen why it is essential to buy a blade that can drill accurate holes without getting damaged. Also, we now understand why it is crucial to have one that is tough and supports performance. That’s why PORTER-CABLE 5558 is our editorial favorite!

First, it accommodates an RPM of up to 10,000. Let’s be honest- most of the machines will run towards that RPM. You need a blade that will not get loose or detach from the cutter even at such high speeds.

Second, it has six teeth. Most joiner blades in our list have eight sharp edges. But that doesn’t mean that six is too less. The six work pretty well.

Third, if you want to cut fast, then you need sharp blades. But, sharpness is not enough- you need strength too! That’s why PORTER-CABLE 5558 teeth are fortified with carbide. Sharp and sturdy teeth will help you cut easily into wood, PVC, or other materials without wearing out.

Also, you should choose blades that are easy to sharpen. Let’s face it- no one wants to be shopping for new blades every single day. You need to be able to sharpen your tools easily. That’s why I vouch for PORTER-CABLE 5558- it can be sharpened. It will save you time and money.

CMT 241.008.04 Biscuit Joiner Blade, 4-Inch Diameter x 8 Teeth, PTFE-Coated

As we’ve already seen, CMT blades are some great woodwork beasts. They are small, compact, and strong! Their sharp well-angled teeth make it easy for you to cut through sturdy materials. And, they support tight cutting angles. Combined, all these features present in the CMT 241.008.04 earn it a spot on our list!

The first thing that strikes your eye is the orange color and eight teeth. It’s important to know how this helps you. First, the color is an assurance that the blade is coated with an anti-corrosive material.

The PTFE is an orange trademark coating from CMT, and it is industrial-level protection from any form of rusting or corrosion. The coating reduces any buildup of pitch or resin, which could destroy your blade.

Apart from life, the CMT 241.008.04 is made to perform. It has a four-inch diameter and weighs as low as 0.01 ounces.

If a warranty is ever worth the consideration for you (for me it’s not necessary when dealing with blades worth less than $20), then you are covered by CMT’s policies. But, that excludes the dull, damaged or sharpened blades. They should just in their original state.

Don’t forget to consider the blade’s size. Remember, this is the only way you are going to buy the right blade for your plate joiner. If your cutter supports blades that measure D 4 100 millimeters, B 22mm, K .157 and P .154, then this is your kind of blade!

Best Biscuit Joiners Blade Buying Guide

Blades are blades, right? No! Don’t just pick every blade you find on the store! You certainly should go for the best, and finding it requires you to pay attention to several factors.

Noteworthy, you are looking for a blade that will not only fit in your joiner but also work efficiently.

Remember; only buy a blade if it solves your problems. Think about this: if you are looking for blades that can cut through hardwoods, then you should not pay attention to those made of brittle metals, no matter how well they fit or how much they cost. Of course, you don’t have to buy a diamond, tungsten or titanium blades- you need sturdy steel blades.

In short, it’s always important to find those blades that work best for you. In this case, find those that fit your machine, cut your precisions, and are sharp enough to cut the material you use.

As a rule of the thumb, have a checklist from which you can compare different blades. The checklist should contain features that you require for a blade. Buy the set of blades with the highest number of ticks on your list.

Fortunately, we’ve come up with features that you should include in your checklist. We hope that they will help you make a smart decision.

Size of your sockets

What is the size of the biscuits you are using? After considering the kind and size of the furniture, you are trying to build, set the right size of sockets. This will let you know what biscuits you should be using. In turn, you’ll be able to find the best size of blades you should be using.

Modern joiners have different cutting depths. Each depths require a unique blade. Make sure you have high-quality joiner blades for each level. This way, you’ll be able to make precise cuts.

Furniture Material

Which material are you cutting through? Find a blade that ably cuts PVC, hardwoods, softwoods or cardboards easily. However, if you are using soft materials, you really don’t need carbide-tipped teeth. The feature is, conversely, compulsory if you are using hardwoods.

The durability of the blade

The durability of the blade depends mainly on the material you are using. If the material is tough, then the blade will last long.

In our review, we precisely picked carbide-tipped blades. You see, ordinary blade tips would break when cutting hardwoods or other strong materials.

The friction between the blades and the material causes abrasion. In short, the edge wears out fast. So, you should find those blades that are strong enough to withstand this.

German steel high-grade steel with six micro-grain carbide-tipped teeth material is good enough when you want blades that can last long.

Compatibility with your joiner

Which biscuit-joining machine are you using? It’s essential to understand the tools you use as they directly determine the accessories you need. Not all the machines will support the blade you are purchasing. So, it’s crucial that you look specifically for the blades that work well with your joiner.

Let’s face it: DeWalt blades might not be the best for Bosch or vice versa. You should be ready to look for the blades that will fit and work efficiently in the biscuit joiner. This will save you the stress and inconvenience caused by blades that never fit your joiner.

Cutting Angle

How are you cutting the wood or PVC? Do you want to make acute angles or just the standard ones? If you are looking for a sharp angle, then you need precise blades. The rule of the thumb is to have sharp blades with a strong edge, and teeth that slant at the right angles.

Weight of the blade

How heavy is your blade? Listen to this: mechanization is all about making work easier. However, this may not be the case if you are working with heavy machines. What’s the need of carrying a whole tractor in your hands in the name of “easy work”?

Bulky blades add to the weight and inconvenience of your machine and thus, they reverse the idea of making your work easy. Blades are metallic, so, you certainly don’t expect them to be as light as the biscuits. However, at least, they shouldn’t be as heavy as the motor!

There’s a thin line between heavy and strong blades. Heavy blades tend to be tough too. And, this means that they are likely to add to the weight of the joiner. While I don’t want to promise that you’ll be working with pen-heavy joiners, at least, they should be light enough to work with.

Blades should weigh about 0.01 to 0.05 ounces. At least, with such a weight, you will never sweat while building your furniture!

In the same way, the ideal size of a biscuit joiner blade is about four by four by 1 inch.

Who needs a new biscuit joiner blade?

Every carpenter- literally! If you are a woodworker, then it goes without a saying that you will require to have smart tools for your work.

Getting old has taught me that I shouldn’t just give up on work yet. Early days of the youth were filled with the urge to keep exercising my muscles (had them!). There was enough time to do everything manually. But that’s long gone. Everything now requires me to take nearly five times longer than during that time.

So, what has changed? The idea is simple- keep doing what you love, but change the means. If you want to continue working beyond retirement, then you have to look for efficient methods.

Good biscuit blades let you cut accurately and faster. A blunt or weak blade would waste not only your time but also your hard-earned money. So, any time, you should find the blades that work best for you!

Verdict on the Best Biscuit Joiner Blades

By now, I believe you have already found the right blades for your plate joiner machine. In my view, PORTER-CABLE 5558 is the best joiner blade for biscuits. Which is your pick?
