2013 Beijing large-scale solar energy exhibition will be held at the end of March
China's vast central and western regions have a high-quality solar energy industry base, and its geographical environment has created favorable conditions for the development of the solar energy industry. However, how solar companies can achieve the desired market effect will become the focus of major solar companies next year. The 2013 Beijing Large Solar Energy Exhibition will be held once again in Beijing Exhibition Hall from March 21st to 23rd. The conference is expected to receive more than 400 exhibiting companies from around the world and purchase 30,000 visitors, which is an indispensable promotion and marketing platform for solar energy companies.

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.
