Carbide burs/porting tools for metal working. Manufactured on premium automated CNC machines, carbide burs are available in three main styles of cuts – single, double and aluma.
Single-cut burs are for general purpose work and provide good material removal. 
Double-cut burs produce smaller chips for greater operator control on applications such as stainless steels and ferrous materials.
Aluma-cut burs have a wide flute design for easy stock removal without loading on applications such as nonferrous and soft materials.
Standard-cut burs are widely uesed and leave a fine finish
The carbide bur line includes more than 175 individual burs and one 10-piece kit and 5-piece kit. Overall bur lengths range carbide burs are used in many industries including automotive, aerospace, foundry, power station and engineering for mold and pattern making, die sinking, tool making and maintenance.

How to use the carbide burr
1.Speed /RPM
The speed at which you use your carbide bur in your rotary tool will depend on the material you're using it on and the contour being produced but it's safe to say you do not need to exceed speeds of 35,000 RPM. The table below shows some approximate speeds.
Diameter of Burr RPM
1.6mm or 1/16"          25,000 - 35,000 
2.35mm or 3/32"       17,000 - 26,000
3mm or 1/8"                17,000 - 26,000
6mm or 1/4"                11,000 - 16,500 
12mm or 1/2"              8,000 - 12,000 
16mm or 5/8"              7,650 - 11,500 
2.Apply only a little pressure
As with all drill bits and burrs, let the burr do the work and apply only a little pressure otherwise the cutting edges of the flutes will chip away or become smooth too quickly, reducing the life of your burr.
3.Keep The Carbide Burr On The Move
When using your carbide burr try not to keep it still for too long as this will prevent the burr from digging and jabbing into your material causing unsightly marks and roughness.
