Cylinder Shape
Cylinder-shaped burrs are ideal for flat surfaces. However, Syndent cylinder-shaped burr rotary file can be divided into three types:
- cylinder with a flat end
- cylinder with end cut
- cylinder with a radius end
Cylinder with a Flat End
Cylinder-shaped burrs that have a flat end (with no cuts) are suitable to grind flat surfaces. The surfaces that do not have corners or angles need a flat end burr.
Cylinder with End Cut
A cylindrical-shaped burr rotary file that has a flat end but you can see cuts on its end. You can conveniently grind a flat surface, with a perpendicular corner, with the help of these burrs.
You can conveniently grind the right-angled corners without causing any damage.

How Many Flute Cuts Are Available in Burr Rotary Files?
Syndent manufactures burr rotary files in numerous flute cuts. The purpose of making different cuts is to make the burrs compatible with different materials.
You can grind, cut, deburr, and polish multiple surfaces with the help of different cuts. These cuts can be divided into two groups.
- Standard cuts
- Unique cuts
Standard Flute Cuts
There are three standard flute cuts Syndent manufactures. These are:
- Single cut flutes
- Double cut flutes
- Flutes with aluminum cut
Single Flute Cut
By single cut we mean the teeth of the burr rotary file are in one direction. These cuts are ideal to remove long metal chips.
You can do the grinding and deburring job quickly with a single flute cut burr. It is due to the aggressive chunk removal by the single cut flutes.
Double Flute Cut
In contrast to the single-cut flute, a double-cut burr rotary file consists of sharp teeth intersecting each other.
The double-sided sharp teeth help to remove the stock finely. It cuts small chips leaving the surface smooth and clean.
Aluminum Flute Cut
Aluminum flute cuts are also one-sided teeth. However, in comparison to single flute cuts, the aluminum cuts are wider and remove the stock aggressively.
Aluminum cut rotary files are suitable to work on non-ferrous and softer materials.
Unique Flute Cuts
Besides the above-mentioned three standard flute cuts, Syndent manufactures some unique cuts as well. These are:
- Coarse flute cut
- Fine single flute cut
- Flute with a foundry cut
- Diamond flute cut
- Chipbreaker flute cut
- Fast mill cuts
All these cuts are appropriate for several purposes. Like:
Grinding
It means removing the excessive metal chunks conveniently from the workpiece.
Engraving
It means that you can engrave your desired patterns on the desired surface.
Honing
Honing is the process of improving the surface finish.
Enlarging holes
Expanding the size of an existing hole is another function that a burr rotary file to smoothly.
Cutting
These burrs can cut any material conveniently. However, burr rotary files are not manufactured for cutting purposes, but you can cut several materials with them in your desired shape and size.
Deburring
The unwanted and excessive material on the workpiece is removed with the help of different flute cuts. It is called deburring.
Some cuts give you a finer finish as compared to others. It depends on burr rotary file flute types.
Shaping
You can conveniently give a metal piece your desired shape by using a specific flute cut.
Leveling
It means that you can level an uneven surface, leaving it flat and smooth. It is also helpful for creating and smoothening a surface before polishing.

Why Some Burr Rotary Files Have Long Shafts?
Some burr rotary files have long shafts to mill the areas where a standard shaft cannot reach. For example, while working on a surface that is deep and narrow, you might need a file that has a long shaft.
In the long shaft files the manufacturing process, shapes, and flute cuts are the same as standard-sized shafts. The only difference is their extra-long shafts.
Syndent’s long shaft burrs are ductile and resistant to shocks. Syndent ensures that the long shaft burr rotary files are tolerant to pressure.
The working speed of long shaft bits is comparatively slower than small shafts. It is because the long shafts tend to wobble more and may vibrate if you increase the speed.
Long shank burrs are available in a size ranging from 3” (75mm) – 12” (300mm). The 6” shaft is the most commonly used size when it comes to long shaft burr rotary files.
Some people use an extension with the standard shafts to increase the length and reach the desires area. But Syndent recommends you avoid adding an extension.
A long burr shaft is better in balance as compared to the extended length tungsten carbide burrs.
Moreover, extensions cost you more than long shank burrs. Same as the standard shafts you can customize the shaft and flute lengths and diameters.
Long shank burr rotary files can perform functions that a standard burr can. It can deburr, cut, mill, grind, and enlarge holes.
If you work on narrow spaces with deep holes, get your long shank carbide rotary files right now and prove to the world your ultimate skills.
At What Speed Shall I Work with My Burr Rotary File?
Syndent prescribes the recommended speed of a specific rotary tool in the manual guide. The speed has a vital impact on the smooth rotation and fine finishing of your work.
Maintaining a moderate speed is necessary because high speed may cause vibration whereas slow speed may end up clogging or damaging the flutes of the burr rotary file.
The size of the shaft head goes in contrast with the recommended speed. It means, that the larger the shaft headless will be the recommended speed.
Similarly, with small head sizes, you can work with comparatively faster speed. Here are few sizes and their speed ranges:
- With a 3mm head size, you can work at a speed ranging from 20,000 – 30,000 RPM.
- 15,000 – 30,000 RPM is the working rate for a 5mm burr rotary file.
- A 6mm shank head may work at a speed of 11,000 – 16,500 RPM.
Whichever burr rotary file you choose, ensure that you have taken the precautionary measures before starting the work.
It is always recommended to put the moving burr rotary file on the workpiece rather than starting the tool after setting the burr rotary file on metal. It would be best to maintain the speed throughout the machining process.
Unstable speed or working on the same point for longer may result in uneven lines and unwanted grinding.
Can I Use Burr Rotary File in Tools Other Than Die Grinder?
The best thing about Syndent’s burr rotary files is that they can be used in multiple rotary tools.
You can conveniently use them with the available high-speed tool you have. Syndent provides you with multiple shank diameters that can fit in the collet of variable tools.
