Imported hollow drill bits, various shank hollow drill bits

Hollow drill bit (rr), also known as core drill bit, hollow drill bit, core drill bit, metal hole opener, hole drill, countersink drill hole opener, hollow tool reamer drill bit, reamer drill bit, magnetic seat drill bit, magnetic drill bit, magnetic drill bit, etc., hollow drill bit The working principle of the drill bit: The cutter head adopts a combination of two or more sets of blades. The combined blades are composed of several outer blades, middle blades and inner blades. During the cutting process, each blade only bears about half of the workload, and there is also a cutting knife on the inside of each blade. Therefore, chip removal can be very smooth. In addition, due to the characteristics of each edge bearing a part of the cutting work, the hole drill is extremely unlikely to cause edge chipping. Hollow drill bit (rr) drill bit classification: high-speed steel drill bit, carbide drill bit, tungsten steel drill bit. Effective cutting depth: Drilling diameter specifications: The main materials of hollow drill bits are high-speed steel, powder metallurgy, and cemented carbide. According to the shank type, it can be divided into: right-angle shank hollow drill bits, flat shank hollow drill bits, universal shank hollow drill bits, four-hole shank hollow drill bits, type right-angle shank hollow drill bits, threaded shank hollow drill bits, etc. Suitable for electric motors: British Magne Magnetic Drill Magnetic Drill /Magnetic seat drill/drilling machine/lathe/milling machine, complete range of specifications, suitable for various brands of imported magnetic seat drills, magnetic drills, such as: Suitable for drilling rigs: Universal handle (three points on one plane) R Alpha Ouba B Bader Beatty Si, etc., the overtone shank (four-hole shank hollow drill bit), the German overtone shank, and the Nitong shank are suitable for imported brands such as Nitong drilling rigs, and the straight shank (flattened shank and two flat shanks) are suitable for various domestic magnetic drills and general-purpose drilling machine vertical bench drills. Milling machines, boring machines, etc. Each drill bit can drill one hole. This product is used with a magnetic base drill, and the drilling efficiency is ~ times that of ordinary drill bits. Each drill bit can drill a hole. For example, it only takes seconds to drill a steel plate with a thickness of Bridge machinery and equipment installation, large equipment maintenance, power plant maintenance and all pipeline projects are welcome and used!
