Product Description

Sandvik top hammer drill bit tungsten carbide button inserts for mine rock drilling
OEM &ODM are highly welcomed upon your drawing or sample.

Sandvik rock tools for top hammer drilling are designed to transmit intensive impact energy into the rock
with the least possible loss of energy. The result is good rock breakage, high penetration rates and high
productivity. Along with optimal hole quality, great reliability and long service life.

Why Do Our Carbide Drill Bits 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 crusher wear parts. How to prolong it's life span is what we
care most.

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.
