Advantage
The CARBDIE ROD provided by Evergreen can adapt to the following processing conditions:
1.Not easy to break and chip under extreme high temperature conditions
2.Improve coating efficiency for tools using chemical vapor deposition (CVD) diamond coating
3.Improve the processing efficiency of titanium alloy and stainless steel materials, because in these applications, the machining risk of fillet chipping is easy to occur
4.In mold processing applications, it can improve the production efficiency of hardened steel with hardness >HRC60

The above are the reference grades recommended by our company for different materials. Please see the attached table for the specific performance parameters of each grade.
Since the blade shape and coating of the tool have a great impact on the use of the tool, the grade recommendation is for reference only.

This kind of competitiveness enables us to achieve better results in facing the actual market demand and tapping the potential market demand, and can bring more and even irreplaceable benefits to our customers.
Explanation: Extra coarse-grained cemented carbide refers to cemented carbide with a WC grain size greater than 6 μm. Compared with coarse-grained cemented carbide, it has better toughness, better thermal fatigue resistance, and higher wear resistance. It is widely used in shield tunneling, mining, stamping dies, cold heading dies, rolls and other industries under extreme working conditions, and product reliability is greatly improved.
Advantages:
1. Can be mirror polished/flat head/chamfered/line cut/tip ground/multiple steps, etc.;
2. Can make various types of needle gauges/plug gauges/gauge gauges/pass and stop gauges.
3. Can process various special-shaped parts/non-standard tools.
