In this review, we give you a step-by-step guide on how our tool works. Follow us.

What is a Router Burr?

A router burr means a tool that can perfectly remove fancy edges on a material surface. You can precisely hollow out or route out an area on specified material surfaces. This may include all hard and soft materials.

Syndent router burr operates with a router. When you look down from the top of your router, you can see the burr rotate in a clockwise direction.

Meaning, when operating, you should guide the router burr to the right from the left-hand side.

The router burr has myriad uses, quite handy for several industrial projects, both decorative and functional. This is common especially for industries that deal with wood.

When used on a router machine, the router burr can provide a range of uses. This includes material trimming, cutting, shaping, grinding, deburring, etc. Can provide efficient uses on metal, wood, plastic, laminates, and so on.

Syndent designs router burrs using quality tungsten carbide steel raw materials. The quality raw materials ensure the development of a quality cutting router bit.

This makes our tool fit well in the industry, providing quality performance on all material surfaces. Tungsten carbide components give our router burr hardness and strength to cut both hard and soft materials.

Our router burr appears in various shapes and sizes to fit different material needs. The shapes include tree, taper, cone, ball, cylindrical and more.

The different sizes of our router burrs can range from 1/16-inch to 1-inch diameter with round shanks.

The router burr has a special design on the cutting edges. The flutes have sharp cutting abilities, thanks to the tungsten carbide materials.

The solid carbide also enables the router burr to have a strong impact on materials when cutting because of the hard nature. They have a low load since they provide an open cut on materials.

For 11 years and above, Syndent has manufactured and furnished the industry with quality router burrs. We supply the market with quality cutting routing burrs for all industrial uses.

What Raw Materials Make Router Burr?

Syndent router burr features quality grade YG7 raw materials which looks similar to K25 in quality and performance.

The raw materials have the highest density that surpasses 90 HRA. Its hardness almost reassembles a diamond that gives good resistance to extreme heat, corrosion, and wears.

In addition to hardness and high density, Syndent designs special cutting edges from the material. You can work effortlessly on hard materials without clogging the flutes.

This reduces the possibilities of the tool heating up easily. Therefore, Syndent router burr has lasting cutting performance on all material surfaces.

Router burrs designed from tungsten carbide steel allow you to cut materials like steel, stainless steel, cast iron, wood, etc.

They can cut metals even when the metal or the tool grows hot. Router burrs made from YG7 or K25 raw materials can metals that lie below HRC70 such as hardened steel and hard non-metallic materials.

What is Tungsten Carbide?

Tungsten carbide refers to a chemical compound that includes tungsten and carbon. This renowned compound in the industry has superior hardness and durability with a high melting point of 2,870 degrees Celsius.

Manufacturers broadly use it in several applications that need superior impact and wear resistance. This includes cutters, abrasives, punches and dies.

By nature, the denser tungsten looks light grey with a melting point of 3,422 degrees Celsius. It has high resistance to corrosion and highly ductile.

When you combine tungsten with carbon, it increases its hardness to about 9.0 on the Mohs scale. This lies just below a diamond.

Router burrs made from tungsten carbide have the highest scratch resistance. The durability makes them ideal choice cutting tools to oversee tasks under harsh conditions. Tungsten carbide appears in different grades, depending on the binders used.

Which Tool Should I Use A Router Burr?

Just by the name, a router burr should perfectly operate well with a router machine. Using a router burr on a router tool, you can complete different jobs faster.

We have varieties of router tools you can choose from. This depends on your material needs and knows exactly what you want the tool to do for you.

How do You Use a Router Tool?

Routers are extremely versatile tools and come in different options. Routers have one thing in common. They have high rotation abilities and when used with cutting tools, they can cut and shape different materials.

We have two categories of routers: fixed-based router and plunge router. The fixed router means you can only make adjustments before you start cutting and not during the process.

A plunge router is quite big in design and features a plunge. This means you can make adjustments during a cut on materials.

The router features two different collet sizes. The collet holds the router burr itself and into a router. Standard router burrs come in a range of between 1/4-inch and 1/2-inch sizes.

Therefore, the collet sizes also come in the same two sizes to fit the shanks of the different router burr sizes.

The router spins the router burr in a clockwise direction. Therefore, when cutting materials using a router burr, you push the machine against the burr rotation. We call this a push cut.

What Uses Does a Router Burr Provide?

Syndent router burr provides a list of several important uses on different materials. When used on a router machine, a router burr provides the user with versatile options on most material surfaces.

Designed with very special geometry and sharp cutting edges, you can cut, shape, chamfer, deburr, create holes, drill, etc.

Router burrs can provide sufficient performance in industries that have projects with demanding needs. This greatly increases productivity and reducing manpower costs.


The unique and sharp cutting edges of the router burr can precisely cut a wide collection of metals and materials.

The hard and high-density features of the tool allow you to make a strong and accurate cut.

Made in different shapes and sizes, a free selection of an appropriate cut style can slice materials into pieces like butter.


Router burrs can also shape materials accordingly when applied correctly. When used on a router machine, Syndent router burrs rotate at very high speeds.

Tungsten carbide has sharp cutting characteristics. Our router burr head features tungsten carbide material which we machine using our advanced CNC machine.

Our advanced machines provide the head with very sharp cutting blades called flutes. These sharp blades of our router burr have high efficiency to shape materials like steel, hardened steel, cast iron, etc.

Material shaping also involves molding. Syndent router burr can help you mold material until you reach the desired shape.


A router tool has greater power which leads a router burr to grind a list of various materials. As one of the steps of making finishes on your material, industries heavily use router burrs in grinding materials.

Through active grinding, you can clear the sharp edges, rough contours and make the material surface smooth.

You can grind materials to make the surface ready for brazing or to remove welds. We have special shapes that appropriately can grind materials, even in tight or hard-to-reach places.

Enlargement of Holes

With Syndent router burr, you can make precise holes on a given material and make them wider as required.

From the various shapes and sizes of our router burr, you can choose an ideal tool to drill or enlarge a hole.

A single cut router burr with single flutes makes an upward cut when used a given material surface. A single cut cuts by creating long chips to form a perfect and accurate drill on your workpiece. Using a ball-shaped router burr accurately increases the size and depth of the hole.


Another way to use a router burr features a process called deburring. This involves removing small pieces of materials on material surfaces. We call the small materials burrs.

They form as a result of different machining processes like cutting, shaping, chamfering, carving, drilling, and more.

Burrs can make a material surface have an awkward design or roughness. Besides making the material very rough to handle, it can lead to inaccurate results on your project.

Syndent router burr can remove burrs and contours for an exact projected final project.

In this case, use a double-cut router burr for a finer and smoother final finish. You can simply make modifications to your piece of material with our quality tool.

Therefore, using Syndent router burr can provide bountiful functions to make your work easier, accurate and faster.

Syndent cutting tools have high precision that guarantees quality results on your projects.

Is Tungsten Router Burr Stronger Than Diamond Router Burr?

Not really.

Diamond and tungsten carbide elements have almost the same hardness and strength as other materials. Diamond has better hardness and strength than tungsten carbide.

It performs better in terms of impact strength as opposed to tungsten carbide and other substances.

When we measure the strength and hardness of tungsten carbide, it also has remarkable performance.

It lies behind diamond but with a better finer finish when cutting or grinding materials.

Diamond leaves a rough finish on surface materials which some industries prefer to tungsten carbide.

Is Tungsten Router Burr Better Than High-Speed Steel Burr?


Most manufacturers make cutting tools from diamond, tungsten carbide, and high-speed steel.

Diamond is better in strength and hardness than the rest of other metals followed by tungsten carbide. High-speed steel comes in last of the metals mentioned here.

As mentioned earlier, tungsten appears as a fine grey powder in its natural form.

Tungsten carbide comprises of same amounts of tungsten and carbon combined. This combination forms a very strong cutting after pressing and shaping it.

The tungsten carbide router burr, therefore, has high density than high-speed steel.

Therefore, router burr made from tungsten carbide can cut materials precisely, easily, and faster than high-speed burr.

Tungsten carbide has tarnish resistance and features hypoallergenic characteristics. It also has high scratch resistance and doesn’t wear easily.

Whether you cut hard or soft materials, router burrs made with tungsten carbide offer a durable cut.

It doesn’t lose its polish easily because of its high hardness and increased durability.

Furthermore, it has good resistance to extreme conditions like much heat. Therefore, it performs better than high-speed steel.

Can A Router Burr Fit in Any Router?

Not true.

A router features a nonadjustable collet where the router burr correctly seats. A standard router burr has a shank size range between 1/4-inch and 1/2-inch.

This implies a smaller router collet can only accommodate the 1/4-inch router burr. A larger router chuck can accept both small and large sizes of router burr shanks.

Which Speed Limits Suits a Router Burr (RPM)?

Advanced routers feature speed adjustment so that you can set speed as required.

You can adjust from a minimum of 8,000 to a higher 24,000 RPM. Not all routers function safely or optimally at the same speeds.

Larger router burrs have the largest mass with the capabilities of vibrating at very extreme speeds.

For example, a router burr that has a cutting surface area of about 3-1/2-inch diameter can travel very fast. It can operate at 24,000 RPM than 1/2 inch router burr cutting surface.

The following table can provide a quick guideline for the maximum speed you can apply with router burr.

Burr DiameterMaximum Speed (RPM)
Up to 1”24,000
1-1/4” to 2”18,000
