Chen Zongqi, R&D Manager of Taiwan Diamond Industry Co., Ltd. Report Analysis: Since the end of the 1970s, Taiwan has begun to focus on the development of information electronics, precision machinery and equipment, and optoelectronics industries. After decades of development, Taiwan has basically established an industrial system with a relatively complete department, a commissioned processing model as the mainstay, and an information electronics industry as the pillar. Among them, smart phones, LCD panels, semiconductors, solar energy and other electronic industries occupy a dominant position.
The diamond tool market in Taiwan is much smaller than the mainland market, and the market size is about 80-8.5 billion US dollars. Among them, the share of diamond tools made in Taiwan (including export) has NT$4.5 billion to NT$5 billion; imports from outside the island accounted for NT$3.0 billion to NT$3.5 billion, of which Japan’s imports are the largest, accounting for about 40% of the total import value. ~45%.
In 2013, the total amount of imported diamonds in Taiwan was 7,4055,000 carats and the CBN was 280,000 carats. 70% of them are used in the semiconductor industry, 14.5% in the machinery industry, and the rest are used in transportation, construction and other industries.
There are more than 80 diamond tool manufacturing and selling companies in Taiwan. The top five diamond tool companies account for 80% of Taiwan's market share, of which Taiwan Diamond Industry Co., Ltd. has a 25% market share.
Figure 1: Analysis of Taiwan's raw materials market
As can be seen from Figure 1, Taiwan's superhard material raw materials market totaled 11.81 million US dollars, of which: CVD and large single crystal diamonds were 2.6 million US dollars, accounting for 22% of the market; diamonds for grinding bits and grinding wheels were 3.48 million, accounting for the market. The share is 29%; the diamond powder is 1.5 million US dollars, accounting for 13%; the CBN and PCBN are 840,000 and 400,000 US dollars respectively, accounting for 7% and 3% of the market share.

Figure 3: Diamond tool application classification
Tungsten carbide drill bits are made of tungsten carbide materials, and their own hardness can up to HRC90 degrees. They are mainly used in the field of metal processing to drill holes on workpieces.
Carbide drills can be divided into straight flute drills, twist drills, 3 flutes drills, deep hole drills, step drills, spot drills,etc.
Applications:
Carbide drills can be used in the Automobile industry, like car crankshaft,Car connecting rod,Integral turbine housing,Car engine block,Air conditioning compressor crankshaft,Electric tool cylinder etc.
