The hollow bit of Shanghai Miaojia mechanical and Electrical Co., Ltd. is also known as core bit, hole opener, hollow cutter, magnetic seat drill bit, magnetic drill bit, etc. the working principle of the hollow bit is that the cutter head adopts two or more groups of three edge combinations, and the three combined edges are composed of several outer edges, middle edges and inner edges. In the process of cutting, each cutting edge only bears about 1 / 3 of the workload, plus the inside of each cutting edge also has a cutting tool. Therefore, it can make the chip removal very smooth. In addition, due to the characteristics that each cutting edge bears part of the cutting work, it is not easy to produce the phenomenon of cutting edge collapse when drilling this hole. The classification of hollow bit bits: high speed steel bit, cemented carbide bit, tungsten steel bit; effective cutting depth: 35mm, 50mm, 100mm, 120mm, 150mm, 300mm; drilling diameter specification: 12mm to 160mm; The main materials of bit are high speed steel, powder metallurgy and cemented carbide. Suitable for motor: magnetic drill / magnetic stand drill / drilling machine / lathe / milling machine, with complete types and specifications, suitable for imported magnetic stand drill of various brands, such as: suitable for drilling machine: universal handle magbroach, UK, Alfra alpha oba, BDS baidebitis, etc., the overtone handle Fein German overtone, the Japanese East handle is suitable for the Japanese East drilling rig and other imported brands, the straight handle (flattened handle) is suitable for all kinds of domestic magnetic drills, as well as general drilling machines, vertical bench drills, milling machines, boring machines, machine tools, etc. Each bit can drill 1000-3000 holes. This product is used together with the magnetic stand drill. The drilling efficiency is 8-10 times that of the ordinary bit. Each drill bit can drill 1000-3000 holes. For example, it only takes 25-40 seconds to drill a hole with a diameter of 40 mm through a steel plate with a thickness of 30 mm, which greatly improves work efficiency and saves a lot of labor and material resources, especially welcomed by steel structure engineering, shipbuilding industry, railway construction, mold manufacturing industry, paper industry, bridge, mechanical equipment installation, large equipment maintenance, power plant maintenance and all pipeline engineering And use!
With the development of science and technology and the improvement of people's living standards, hollow bit is to use hollow bit to pick up materials, or to cover holes on steel plate, which brings convenience to people's life. When it comes to hollow bit, many people will ask the price of hollow bit, and the manufacturer of hollow bit will even ask where the quality of hollow bit is the best. Miaojia's hollow bit enjoys a good reputation in the industry. Miaojia's superb technology ensures that the quality of the hollow bit is higher than that of its peers, and the lower price of the hollow bit ensures Miaojia's leading position in the industry.
