High Efficiency Hss End Mill HRC70 Processing Hardness With Easy Operation

Carbide Burr, Taper with Ball Top, Dia:2mm~16mm

Advantage of our carbide burrs

100% quality and brand new.
Can Process a variety of metal and non-metal, processing hardness would up to HRC70.
In a great part of the work, it can replace the petiole small wheel, and no dust pollution.
High production efficiency, the processing efficiency is several times higher than file, nearly 10 times higher than small wheel stalk.
High product processing quality, high finish, can process out a various of high-precision mold cavity.
Long life, the durability is 10 times higher than high-speed steel cutting tool, 200 times higher than small grinding wheel.
Easy to use, safe and reliable, can reduce labor intensity, improve the working environment.
Suitable for processing these metal and non-metal, such as cast iron, cast steel, bearing steel, high carbon steel, chrome-nickel alloy, bronze, brass, and ceramic tile, marble, jade, bone, etc.

Cut Shape

1. Double-cut burs produce smaller chips for greater operator control on applications such as stainless steels and ferrous materials.
2. Aluma-cut burs have a wide flute design for easy stock removal without loading on applications such as nonferrous and soft materials.
3. 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.

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. 1.6mm or 1/16" 25,000 - 35,000
2. 2.35mm or 3/32" 17,000 - 26,000
3. 3mm or 1/8" 17,000 - 26,000
4. 6mm or 1/4" 11,000 - 16,500
5. 12mm or 1/2" 8,000 - 12,000
6. 16mm or 5/8" 7,650 - 11,500

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.

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.
