SDS Plus and SDS Max drill bits can be used for drilling operations in concrete, reinforced concrete, granite and similar materials. SDS-Plus has a drilling diameter of 4mm to 32mm and a drilling depth of 110mm to 1000mm; SDS-Max has a drilling diameter of 12mm to 52mm and a drilling depth of up to 1200mm.

Jiaozuo is a city that is prospered by coal and trapped by coal. The data shows that the city's coal reserves are 9.1 billion tons. From the time of coal excavation to the early 1990s, the added value of coal-related industries accounted for more than 90% of the city's industrial added value. But like many resource-based cities, the near-exhaustion of coal resources is nothing short of a bottom-up.
Such a city has achieved remarkable results in the transformation and development, realizing the transition from “black impression†to “green theme†and from traditional industries to emerging industries. At present, the proportion of coal industry's output value to the city's economic output has fallen below 3%; the replacement industry has begun to take shape, initially forming a strategic support industry with aluminum, automobiles and parts, coal and salt combined chemicals, equipment, food, and biology. And new industrial systems focusing on four emerging industries: wind power equipment, photovoltaics, optoelectronics and new materials.
Taking the transformation of the chemical industry as an example, Jiaozuo focused on transforming and upgrading the chemical industry and building a coal-salt joint chemical base in the central region. The four major industrial chains of salt chemical, coal chemical, coal salt chemical and waste resources were used as the main body to build a chemical industry. Raw materials, synthetic materials, and special chemicals are the core coal and salt joint industry layout, and the development of chlor-alkali, soda ash, coal chemical and other industries has been promoted, and a number of chemical industry systems have been formed.
At the same time, Jiaozuo focuses on the tasks of undertaking industrial transfer and cultivating emerging industries, focusing on cultivating four emerging industries of wind power equipment, photovoltaic, optoelectronics and new materials, and developing products and technologies such as wind power brakes, hot stamping materials and superhard materials. A group of emerging industry backbone enterprises.
At present, Jiaozuo has entered the stage of transformation and tackling, and where to turn and how to turn is the top priority for the Jiaozuo Municipal Party Committee and the Municipal Government. Chen Xiang, director of the Jiaozuo Municipal Development and Reform Commission, said that Jiaozuo’s heavy industry has a large proportion, high energy consumption, unoptimized structure, and no adjustment, and the road will only become narrower and narrower. He believes that the promotion of energy-saving emission reduction, the promotion of recycling-type production methods, and the reduction of energy consumption and waste production in the production chain from the source are the key to industrial structure optimization and industrial transformation.
Not long ago, the Jiaozuo Municipal Committee put forward the overall working ideas of “concentrating, strengthening, tackling, striving for first-class, green developmentâ€. The reporter interviewed the Raw Materials Industry Division of the Jiaozuo City Bureau of Industry and Information Technology and learned that the specific implementation plan for the next step of the transformation and development of Jiaozuo City is currently under study. According to the deployment of Jiaozuo City Master Plan (2008~2020), Jiaozuo City will strive to build a new industrial city with deep development of resources and new materials. Its industrial development focus is based on the existing foundation, further cultivating pillar industries such as energy and fine chemicals, extending the industrial chain and forming pillar industrial clusters; using advanced and applicable technologies to transform and upgrade traditional industries such as building materials, plastics and textiles, with key developments. High-tech industry, to achieve the goal of "industrial strong city."
In the “Overall Plan for the Economic Transformation of the Central Plains Economic Zone in Jiaozuo Cityâ€, Jiaozuo City will accelerate industrial transformation and upgrading. The specific goal is to transform and upgrade traditional industries such as chemical industry by 2020, in accordance with the extension of industrial chain and resource recycling. The idea is to improve the in-situ conversion rate of primary products with in-depth processing. Relying on key enterprises, we will promote the development of the park, diversify the downstream processing industry, and accelerate the transformation of coal chemical industry, salt chemical industry and fluorine chemical industry from raw material chemical industry to fine chemical industry to form a circular economy industrial chain. Cultivate and develop leading industries such as biology, new materials, and new energy, and actively develop industries such as lithium batteries, solar cells, and amorphous silicon thin-film batteries, and foster new energy industry clusters.
Standing at the new starting point of the transformation of resource-based cities, Jiaozuo City is full of confidence, and the problems left over from the exhaustion of resources are expected to be resolved. In the future, it will strive to be the main battlefield for maintaining the security of energy and resources and promoting new industrialization and urbanization.
SDS Drill Bits are available with two (properly shaped integral straight edges), three (star arrangement) or four (integral cross arrangement) inserts, made of cemented carbide. They are deeply embedded in the steel head with industrial solder and are characterized by a high degree of mechanical and heat resistance.
SDS Plus and SDS Max Bits should not only be selected based on the diameter of the drilled hole, but also their depth standard. Both of these measures are necessary to maximize productivity.

Taijiquan, Yuntaishan, the four big Huai medicines, industrial agglomeration... Nowadays, the impression of Jiaozuo “Coal City†has gradually faded from people’s memory, and replaced by the development of new titles and new business cards in these cities. As the first pilot city for resource-exhausted urban transformation in the country, and the construction of the economic transformation demonstration city of the Central Plains Economic Zone, Jiaozuo's valuable exploration experience in the transformation of resource-based cities is called the “Jiaozuo phenomenon†by the outside world.
