Looking at
China, Voice of America , senior researcher at the Peterson Institute for International Economics in Washington, USA, Arvind Subramaniah believes that after leading the world economy for three centuries, the West will soon Under the increasingly strong rise of China, it seems to be eclipsed. The renminbi may replace the dollar in the next 10 years and become the world's major reserve currency. Along with the expansion of China's economic scale, the exchange rate mechanism of the Chinese renminbi is constantly being reformed and improved. Since China abandoned its peg to the single dollar exchange rate system in July 2005, the exchange rate of the renminbi has been exchanged from about $8.20 at the time of the US dollar to about 6.3 yuan. At the same time, China is gradually promoting the internationalization of the renminbi. The Financial Times said that not long ago, China officially recognized London as one of the offshore trading centers of the renminbi, indicating that the renminbi is taking another step toward liberalization and internationalization. Monetary analysts are therefore expected to shorten the time for the full free exchange of RMB. Subramanian said that the internationalization of the renminbi will eventually become an international reserve currency. In terms of technology, the renminbi must be freely convertible. China's financial system should be more open, but the most important thing is the political will of the Chinese government. He said: "But the most important condition is that there must be political will to manage the cost of the internationalization of the renminbi. If the renminbi is internationalized, the financial system must be reformed and the renminbi exchange rate should be further appreciated. Therefore, there must be political will to overcome Any possible opposition and resistance.†The benefits brought about by the internationalization of the RMB will be obvious, including the higher efficiency of the financial system; the economic growth model will be dominated by domestic demand rather than external demand; inflation will be further suppressed. However, measures such as expanding domestic demand, reducing exports, and appreciating the renminbi will cause tremendous pressure on exporting companies, a large number of employees will be laid off, and factories and enterprises will close down. Subramanian said that when the United Kingdom dominates the world, the pound is an international currency; when the United States dominates the world, the dollar is the international reserve currency; will China be different in the future if China dominates the world?
Masonry Drill
The masonry bit is a variation of the Twist Drill Bit, the bulk of the Tool is a relatively soft steel, and is machined with a mill rather than ground. An insert of tungsten carbide is brazed into the steel to provide the cutting edges.
Masonry bits typically are used with a Hammer Drill, which hammers the bit into the material being drilled as it rotates; the hammering breaks up the masonry at the Drill Bit tip, and the rotating flutes carry away the dust.
Hammer drill bits often use special shank shapes such as the SDS type, which allows the bit to slide within the chuck when hammering, without the whole heavy chuck executing the hammering motion.
Masonry bits of the style shown are commonly available in diameters from 3 mm to 40 mm. For larger diameters, core bits are used. Masonry bits up to 1,000 mm (39 in) long can be used with hand-portable power tools, and are very effective for installing wiring and plumbing in existing buildings.
