Tungsten carbide rotary burr is probably the small carbide tools used in different industries such as machinery, automobiles, ships, chemicals, craft carving, and the like. Glowing be utilized for deburring. A high level tungsten carbide rotary burr beginner, you may well be wrongly identified as countless varieties of tungsten carbide rotary burrs. You may be thinking what are the right configuration of carbide rotary burrs to decide on, what type is a lot more suitable, and just what should pay attention to. In this passage, you will find 7 strategies for tungsten carbide rotary burrs beginners that will help you select the one more beneficial.


You can discover through the following aspects:

1. Shape
2. Size
3. Fitting
4. Direction
5. Grease
6. Pressure
7. Speed

1. Shape

There are many different shapes of tungsten carbide rotary burrs. They may be tungsten carbide cylindrical rotary burrs (A type), tungsten carbide cylindrical rotary burrs (C type), tungsten carbide spherical burrs (D type), tungsten carbide oval burrs (E type), tungsten carbide arch round nose burrs (F type), tungsten carbide arch pointed nose burrs (G type), tungsten carbide flame burrs (H type), tungsten carbide 60°cone burrs (J type), tungsten carbide 90°burrs (K type), tungsten carbide conical round nose burrs (L type), tungsten carbide conical pointed nose burrs (M type), tungsten carbide inverted cone burrs (N type), etc.

2. Size

A bigger carbide head has higher efficiency. So, deciding on a reasonable big head can speed up work and save you time. The top diameter might be 3mm, 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, and the like.

3. Fitting

Choosing the right chuck is vital for a tungsten carbide burrs beginner. Usually, 4 common varieties of chuck/ holders will be used. They may be hydraulic tool holders, multi-clamp tool holders, universal tool holders, and shrink-fit holders.

Hydraulic Tool Holders

A hydraulic tool holder is a tool-holding system well suited for most machining applications. The hydraulic tool chuck adopts a power tool clamping method completely different from conventional chucks. The force is created by a screw mechanism. By operating the screw mechanism, uniform hydraulic pressure may be generated in the chuck. This pressure is transmitted for an expanding steel sleeve that clamps the tool.

Multi-clamp Tool Holders

The structural kind of the multi-clamp tool holder is quite simple. The tool is firmly clamped in three positions having a ground polygonal hole. In high-speed cutting machining, multilateral clamping is a perfect tool clamping method, because the clamping in the tool is realized by the elastic deformation from the collect. Is generally considerably it holder is its compact design.

Universal Tool Holders

Universal tool holders can be purchased in two styles. An example may be for light-duty machining and one is good for medium to heavy-duty machining. An essential benefit from the universal tool holder is that it has good vibration damping, which may improve tool life and workpiece surface finish quality, and it is cost is just like most high-end socket tool holding systems.

Shrink Fit Holders

Shrink fit holders provide the leading of thermal expansion and contraction, and adopt induction technology to heat the chuck. Shrink fit tool holders have many advantages, mainly including high radial runout accuracy, high transmission torque, and comparatively small shape design. When it comes to vibration-damping performance, shrink-fit chucks are inferior to hydraulic chucks and multi-clamp chucks.

With the chucks or holders, workers also need to be careful. To start with, workers should better make use of the correct chuck for corresponding burrs and check the concentricity from the machine to prevent tremors and shock. Otherwise, it’ll cause premature wear. Then, the grabbing position needs to be at least 2/3 in the shank.

4. Direction

Just what the beginners should look closely at is because they must move burr head one way, from left to right, or from right to left. If you move it forwards and backwards, it may premature wear and cracks inside the cutting edge.

5. Grease

When you’re processing highly viscous materials you’d better use lubricating oil or grease to prevent carbide burr that doesn’t work, as a result of blockage of chip removal groove.

6. Pressure-use an appropriate pressure

An appropriate pressure must be used during work. Much underhand could cause the temperature being way too high to dissipate. It may well even cause the welding part to disappear.

7. Speed

Even though you may are certainly not using tungsten carbide burrs, RPM is definitely a crucial thing you must love. For tungsten carbide rotary burrs, reasonable operating speed is very important to own required level of cutting and workpiece quality.

Try to find the highest speed inside allowable range, because low speed will reduce chip removal performance and produce trembling, which leads to reduced tool life and poor surface finish.

Workers ought to choose a proper operating speed for every type of rotary carbide burr in line with the specific application. There’s 2 methods, where you can try to modify speed with a suitable number.

Method 1

Increasing speed can improve processing quality and lengthen tool life, however it could potentially cause the shank to interrupt;

Method 2

Reducing speed will assist to quickly remove material but can increase the risk for system to overheat and cutting quality to fluctuate.
