Why choose Carbide Inserts

1.Higher speeds and feeds allow more aggressive machining. Carbide
insert tools hold their cutting edge hardness at the very high machining
temperatures created at high speeds and feeds. High speed steel tools must be run
at lower speeds and feed as their cutting edge softens at a much lower
temperature.

2.Hold size longer than high speed steel tools. The carbide insert provides exceptional
wear resistance at the cutting edge.

3.Last longer due to carbide insert forming surface resisting wear as the chip being
formed flows over the tool. Cratering is minimized and the tool's structural
strength is maintained. High speed steel tools crater rapidly and structurally fail
prematurely when machining abrasive materials.

4.Carbide Insert are high hardness and good abrasion resistance.

FAQ

Q:What is cemented carbide ?

A: Cemented carbide is a hard material used in machining tough materials such as carbon steel or

stainless, as well as in situations where other tools would wear away, such as high-quantity production

runs. Most of the time, carbide will leave a better finish on the part, and allow faster machining. Carbide

tools can also withstand higher temperatures than standard high speed steel tools.

Q:What are the key properties of cemented carbides I should be concerned with when selecting a grade for my application?

A: The key properties of cemented carbides that define their performance level for different applications

include abrasion resistance (directly related to the hardness of the grade), fracture strength, and fracture

toughness. In general, the abrasion resistance or hardness of any grade is inversely proportional to its

fracture toughness. Very often grade selection involves finding the best compromise between abrasion

resistance and toughness. In some instances strength and corrosion resistance can be important

factors in the grade selection process.

Q: Which properties are important in metal cutting applications?

A: Depending upon the type of metalcutting operation (turning, milling, drilling, etc.), different combinations

of properties is needed in order to obtain optimum results. For example, in turning and drilling applications

the cutting tool is in continuous contact with the workpiece. Hence, for these applications, abrasion

resistance and strength are the most important properties to consider. However, in operations such as

milling, which invariably involve interrupted cutting, and hence high impact forces, toughness can be an

important factor. Grades employed for metalcutting applications are usually based on fine to medium

hard phase grain sizes (0.5 to 1.5 mm) and low to medium Co contents (6 to 15 wt.%).

Q: Which grades are useful in metal forming applications?

A: In contrast to metalcutting (where abrasion resistance and strength are of paramount importance),

cemented carbides used in metalforming applications will invariably be subject to high impact and

shock forces. Hence, grades used for metalforming applications must possess high toughness

levels with adequate abrasion resistance and strength. Grades employed for metalforming applications

are typically based on coarse grain sizes (3 to 8 mm) and high binder contents (15 to 30 wt. %).

Q: Which grades are useful in earth drilling or boring applications?

A: In many respects the characteristics of the grades employed for earth drilling and boring represent a

compromise between the characteristics that are important for metalcutting and those that are important

for metalforming applications. Grades for earth drilling and boring must possess the highest toughness

levels for any given abrasion resistance level, while simultaneously possessing adequate strength levels.

The best compromise is usually arrived at by using grades that are based on coarse grain sizes (3 to 8 mm)

and relatively low Co levels (6 to 16 wt. %).

Q: How can I choose the most suitable products for my applications?
A: 1.Correct installation site depends on specific size and drawings. Especially for dies processing,

drawings can ensure the finished products are qualified.

2. Processing objects and working environment is determined by cemented carbide grades.

Products' lifetime can be greatly extend if grades are right.
