Carbide Rotary File – The Ultimate FAQ Guide
Welcome to the FAQ page of the carbide rotary file. Syndent manufactures high-grade rotary files to make grinding easier for you.
In this write-up, you will get answers to all your questions regarding rotary tools. Read further to know more about their types, shapes, specifications, and advantages.
Let’s get started.
What Is a Carbide Rotary File?
Carbide rotary file is a high-speed power tool. It is used to grind, mill, deburr, and clear the surface for polishing.
You can use your carbide burrs on numerous metals and materials. Syndent uses cobalt–tungsten carbide to manufacture high-grade carbide rotary files.
Syndent carbide rotary files are available in variable shapes and sizes. You can also get custom-made rotary file sets on demand.
The tin-coated flutes of Syndent rotary bits are anti-corrosive. Moreover, these burrs are heat-resistant.
You can enjoy excessive grinding without the fear of rust and damage.
How Does Syndent Manufacture Durable Carbide Rotary Files?
Syndent uses high-grade tungsten carbide to manufacture strong and durable carbide rotary files.
Tungsten along with fine carbon particles makes a strong chemical compound that is helpful in the making of rotary burrs.
CNC Machines
Syndent has 40 sets of advanced 6-axis CNC machines. Your carbide rotary files are manufactured in these up-to-date machines.
The raw material Syndent utilizes is obtained from state-owned authentic tungsten carbide suppliers.
The QA/QC team at Syndent verifies the quality of the raw material before the manufacturing process starts.
Shaft & Flute Brazing
After getting the high-grade raw material the raw shaft and flute are joined together by the brazing technique.
Brazing is a process in which a melted material is used to join the two metals. Unlike welding and soldering, silver is used as a brazing material to fill in and join the two parts.
Testing
After joining the two parts, Syndent works on the accuracy of the carbide rotary files. One of these tests is balancing, and bending is the other.
In the balancing test, Syndent checks the tolerance of the burrs. It is because of this test that the rotary files are able to facilitate you with vibration-free grinding.
After the balancing test, experienced technicians conduct the bending test on your rotary carbide files.
The purpose of the bending test is to check the flexibility of the shaft. Syndent precisely inspects the ductility so that the carbide rotary files can resist the pressure while working against hard materials.
Flute Construction
The next step Syndent follows is to give the flute its required shape and cut. Advanced CNC machines are used to shape the flute in a predetermined shape.
After giving the flute a precise shape it is further treated to make sharp cuts on it. Syndent provides you with variable standards and unique cuts.
The sharp cuts speed up your grinding process.
Final Work
In the end, the carbide rotary files are adequately polished. You can get customized artwork on your rotary files (on demand).
The smooth and finely finished burrs are then packed to be dispatched. Get ready to receive your consignment!
The precise manufacturing process under the guidance of quality control inspectors guarantees high-quality rotary files.
How Is Carbide Rotary File Beneficial in Grinding?
Carbide rotary files are very useful in the grinding process. You can get the desired results in less time while working with Syndent’s rotary bits.
The main reason behind the adequate grinding is the durability and reliability of Syndent’s rotary files.
The other reasons that influence the grinding process are:
Variable Sizes
Syndent manufactures carbide rotary files in a wide range. The variety in the sizes allows you to grind wide areas as well as small and narrow spaces.
The sharp flute teeth grind quickly no matter what size you choose.
Multiple Shape
Cylindrical, ball-shaped, round, tapered, you name it and Syndent will provide you with all the possible shaped burrs.
Each shape is suitable for specific purposes. You can enlarge holes, treat right angles, and contour round edges conveniently with Syndent’s grinding tools.
With Reference to Cuts
The grinding becomes easier when we talk about the various flute cuts that Syndent manufactures.
There are three standard cuts – aluminum, single, and double-cut. Other than these three you can use burrs with unique flute cuts.
The sharp teeth remove the excessive material from the surface conveniently, giving a smooth finish to your workpiece.
Some flute cuts like double-cut flutes give finer grinding as compared to single-cut flutes. On the other hand, if you want to remove unwanted metal quickly from the workpiece, use single cut or aluminum cut carbide rotary files.
Can I Drill in Hard Metals with Carbide Rotary File?
Yes, you can!
It is not recommended though.
Syndent’s carbide rotary files are not made for drilling. The main purpose of the carbide rotary file is to grind, deburr, shape, or enlarge holes.
Drilling machines and die grinders work on different RPMs. The collet sizes and bit sizes differ in both rotary tools.
Usually carbide rotary files are small in size and are not suitable for a drilling machine.
The small burrs might shatter into pieces due to the incompatibility with the tool.
Moreover, die grinders are high-speed rotary tools. On the other hand drilling machines work at the comparatively slower speed.
So, the incompatibility in speed might damage the burrs and their working efficiency.
However, the strong tungsten cutting burrs may help you to drill through numerous materials, in time of need.
How Many Types of Material Can I Deburr with Carbide Rotary File?
Syndent’s rotary files are versatile in nature. You can use them on several metals and materials.
Besides versatility, Syndent’s durable and strong burrs are available in variable cuts. Each cut is beneficial for different materials.

How Durable Are Syndent’s Carbide Rotary Files?
Syndent’s rotary files are made with high-grade tungsten carbide. The strength of tungsten carbide makes the cutting burrs durable and reliable.
Due to the strong raw material, Syndent’s carbide rotary files enjoy 30% longer life span as compared to HSS burrs.
Moreover, the tungsten carbide rotary burrs work 4 – 7 times faster than HSS files. The sharp flutes give you the desired results in no time.
The ductility of the raw material allows you to deburr hard metals and materials without wearing them out.
The unique K25 material used to make flutes ensures that the flute doesn’t get blunt. The hard and durable flutes are designed specifically to maintain their teeth and sharpness.
However, it is very important to use your rotary files with care. You can increase the life of your carbide rotary files by:
- Following the recommended speed
- Maintaining an adequate pressure
- Cleaning thoroughly
- Storing in a specific packaging
- Working in the recommended direction
How to Choose the Right Carbide Rotary Files for Different Positions of the Workpiece?
It is very important to understand which burr you need to machine a specific area. For example, you may come across flat surfaces, round edges, narrow holes, or right angles.
Syndent facilitates you with exemplary flute shapes and sizes to cope with all situations.
Let’s find out which shape is ideal for what purpose.
Flat Surfaces
To machine flat surfaces Syndent provides you with cylinder-shaped carbide rotary files. These burrs are ideal to clean excessive material from flat surfaces.
Cylinder-shaped carbide rotary files are further available in two end styles – flat end and end cuts.
Cylinder-shaped carbide rotary files that have flat ends are ideal to work in flat places where you do not need to work on corners or perpendicular spaces.
Whereas in spaces where you need to grind the perpendicular surfaces you need to have a cylinder-shaped burr with end cut. Read more!
Flat Surfaces with Right Angles
Sometimes you come across spaces with right angles. Grinding such areas has never been so easy before Syndent’s cylinder-shaped carbide files with end cut.
The sharp teeth on the end of the cylinder help to mill both sides of the angle without damaging the corner.
Flat Surfaces with Curved Corners
If you are working on a flat surface that has a round or arced corner, how will you grind it?
The flat ends of your burr will damage the roundness and will make indecent lines on the surface.
To deal with such situations, Syndent presents the high-grade cylinder-shaped carbide rotary files with a radius end.
The round edge of the burr fits in the round corner of your workpiece, hence providing you with the desired results.
Round Edges
What if your workpiece possesses round edges?
How will you machine the rounded ends without causing damage?
Syndent manufactures multiple carbide rotary files for milling different round edges. For example:
- Ball-shaped burrs to mill round edges
- Oval shaped rotary files for removing round edges
- Flame shaped carbide rotary files for machining arced edges
However, if you have round edges on a long and narrow surface, read further to know about the appropriate burrs for such spaces.
Long and Narrow Positions
To contour the round edges in a long and narrow surface you can have multiple burrs. Such as:
- Tree-shaped burr with a pointed end
- Tree-shaped rotary file with a radius end
- Tapered burr with a radius end
- Tapered carbide rotary file with a pointed end
Holes
Sometimes you need to work on holes. To chamfer, the inner side of the hole Syndent manufactures cone-shaped carbide rotary files.
Inverted cone-shaped carbide rotary files are suitable for rear side chamfering of the hole.
Why Does Aluminum Clog on Carbide Rotary File?
There are three reasons for metal clogging on the rotary files. These are:
- Heat caused by friction
- Prolonged grinding on one place
- Working at a slow speed
Heat Caused by Friction
When you work on an aluminum workpiece, small metal chunks chip out from the surface.
The heat caused by the contact of high-speed carbide rotary file with the metal surface melts the small chipped-out aluminum chunks.
This melted aluminum clogs in between the flute teeth. Clogging causes inefficiency in the burr to cut and deburr.
Besides aluminum, soft materials, that melt due to the heat caused by friction, clog on the flutes, for example, plastic and PVC.
Prolonged Grinding on One Place
Another factor that causes clogging is if you do not keep the burr moving on your workpiece.
If you keep the burr still, in one place, for a prolonged time it may cause the metal to clog on your carbide rotary file.
It is recommended that you keep your burrs moving. The rotary files like carbide burr for aluminum are specifically designed to mill aluminum.
It would be best if you keep the instructions in mind while working on aluminum. A constant moving burr gives you smooth and fine finishing, leaving the surface smoother.
Working at a Slow Speed
If you work at a very slow speed it may also end up in metal clogging. It would be best if you work according to the recommended speed by the manufacturer (Syndent).
However, if, due to any reason, you find your carbide rotary file clogged, (don’t worry) you can clean it.
How?
Read further to learn the ways to clean your clogged carbide rotary file.
How to Clean the Clogged Carbide Rotary File?
There are several ways to clean the clogged rotary file. You can ad0pt the one that suits you.
These are:
- Use acid
- Used caustic soda
- Mill the burr on a hard surface
- Use lubricants
- Use a wire brush
- Burn the clogged wood dust
Use Acid or Caustic Soda
Acid (HCL) or caustic soda (choose one) is an ideal solution to unclog your carbide rotary files. Soak your clogged burr in the muriatic acid/caustic soda for 10 minutes.
Rub the flute with a hard brush to remove the clogged metal. If needed, soak for another 10 minutes.
Syndent manufactures carbide rotary files in a specific way that the flute remains safe from the acid. However, avoid acid contact with the shaft.
Mill the Burr on a Hard Surface
Sometimes when your burr is not immensely clogged, you can unclog it by milling it on a hard surface. In this way, all the clogged material chips off the burr leaving it neat and clean.
Use Lubricants
Some lubricants work amazingly to avoid clogging. Unclogging a lubricated carbide rotary file is easier than a dry burr.
To apply a fine amount of lubricant on your burr before grinding and enjoy easy unclogging.
Use a Wire Brush
Sometimes all your need is a wire brush. Rub it off against the rotary file. Your router bit is clean.
Burn the Clogged Wood Dust
If your burr is clogged with wood dust, you can burn the dust off. Use a small burner to unclog the burr.
Or, sometimes scrap removing liquids also do better in removing the wood particles.
How to Use Carbide Rotary File to Have a Longer Tool Life?
Besides the fact that Syndent manufactures carbide rotary files with high-grade raw material, there are specific techniques that can make the life of your carbide rotary files even longer.
These techniques are:
- Ensure that the burr keeps moving while machining on a specific surface. Milling in one place for a long may destroy the workpiece and also cause damage to the rotary file.
- Apply moderate pressure on the rotary file. Too much pressure may cause damage to the flute teeth.
- Speed is another important factor that determines the life span of your carbide rotary files. Always work at the recommended speed.
- After every use, clean your burr thoroughly and store it in a dry and safe container.
- It would be best if you use your carbide rotary file in the direction of the rotation. It not only gives you fine results but also prevents you from kickback actions.
- To increase the life span of your rotary files, always use them incompatible tools. For example, using carbide rotary files in drilling machines may end up in broken files.
Why Some Carbide Rotary Files Have Long Shafts?
You might have seen Syndent’s long shaft carbide rotary file. It is a state-of-the-art burr that has made grinding easy in hard-to-reach areas.
For example, what if you work in an automotive company and you need to deburr a component that is installed deep down?
You cannot always remove the component, sometimes you have to fix the problem in an intact position.
For such situations, Syndent provides you with long shank carbide rotary files. These burrs have longer shanks than standard carbide rotary files.
You can conveniently reach the areas which are not possible to mill with standard bits.
Besides the long shank burrs that Syndent provides you, you can also get custom-sized shanks.
According to your industry’s demand, Syndent’s engineers can manufacture the ideal solution.
Note: The working speed differs in long shank carbide burrs from a standard one.
Does Syndent’s Carbide Rotary File Rotate Smoothly?
Yes!
Syndent’s engineers ensure the accurate balance of your carbide rotary files at the time of production.
The reason behind conducting the balancing test on each burr is that you get a smooth rotation while machining.
Apart from the accuracy, there are other factors that affect the smooth rotation. Such as:
- If your burr is not tightly screwed in the collet it might cause vibration.
- Conventional cutting may also result in kickback actions.
- To avoid a sudden jerk, start the carbide rotary file firstly and then put the burr on the workpiece. In comparison, if you do it the other way, get ready to handle the bounce.
- Moderate pressure and adequate speed also help in the smooth running of the rotary file.
- Most importantly, never work with damaged burr. It not only causes vibration but may also cause severe injuries.
