Product Description

Kennametal Round Shank Cutter Bits for Planings Road Milling
OEM &ODM are highly welcomed upon your drawing or sample.

The components of a round shank bit:

-Tungsten Carbide tip
-BrazingSteel body
-Wear plate
-Clamping sleeve

Carbide bit tip made of tungsten carbide and cobalt
The carbide tip is a composite material made from tungsten carbide and cobalt. The tungsten carbide
portion influences the wear resistance. Cobalt, by contrast, binds the tungsten carbide grains, providing
for breaking strength / impact strength under the most severe stresses. The quality of the tungsten carbide
is an important factor in the service life of the round shank bit, which in turn influences the milling
performance of the machine.

General influencing factors on bit wear include:
Milling material - Grain characteristics, strength, hardness, binder
Weather - Temperature, humidity, precipitation
Machine - Bit cooling, advancing speed, milling cylinder speed, driving pressure, type of machine and power
Machine operator - Technical knowledge, experience
Bit selection - Clamping sleeve, wear plate, design of bit head and tungsten carbide

Why Do Our Carbide Tips Perform Much Better Than The Others?
Except standard grade, we custom-make Grade of the carbide by analyzing customer's local/site working
conditions (e.g. feed size, type, gradation, hardness, screen size, etc).
That means we customize the grade from the first step mixing raw materials, control the temperature and
pressure when sintering, and finally use different welding techniques to make our wear parts suitable for
certain working condition.
Our Factory is located in ZIGONG City(China Tungsten Carbide Production Base), Sichuan Province.
The quality stability of carbide bar is the core for milling wear parts. How to prolong it's life span is what we
care most.

Our Standard Carbide Grade

Grade: MT6Z

Hardness: 90.5 - 91.0HRA

S.T.R.: 1800 - 2000Mpa

Density: 14.90g/cm3

Grain size: 1.0 - 1.6μm

 

Q&A:

1. Why You Say Your Tungsten Carbide Tips Have Much Better Performance?
-Coarse enough of grain size to be favorable for welding, especially in cold weather.
- Lower Cobalt without broken, longer wear-resistance.
We never stop finding better grade with much longer wear-resistance to save clients' cost. Now we are testing
new grade with coarse grain size for Europe market, it works well. Also we are making another 3 kinds of new
grade to test and compare with current grade. If it goes well, next step we will try to test it for America market first.

2.How You Control the Quality of The Carbide Tips?
-Much strict control on scrap carbide to ensure stable quality of carbide powder.
All is from qualified carbide rods with grain size 0.8-1.0um, like end mill, reamer, drills. Other carbide
manufacturers usually use carbide drill bits or anvil with grain size 1.2/1.6/2.0 mixed.
-Our special creative sintering process to ensure uniform grain size 2.4um.
Carbide manufacturers usually sinter it by Intermediate Frequency Furnace with temperature 1500ºC, that the
heat-difference can be 70-80ºC causing non-uniform grain size. We use Vacuum Sintering Furnace with "secret"
temperature without heat-difference to ensure uniform grain size 2.4um.

3.Do You Accept OEM&ODM?
Yes, for sure, we can cutomize the grade and shape upon your drawings or samples. Such as, make the grain coarse or add
more cobalt to increase its hardness. Make balance on hardness and toughness.
