High speed steel deep hole drill for metal drilling - GD

The hard alloy drill gun represents the advanced and highly-efficient hole processing technology.It can not only be applied to deep-hole (diameter-length ratio1:250) processing, but also the shallow-hole processing(diameter-length ratio1:1). It consists of three parts, the drill handle, drill rod and drill head by welding them together with a throughhole in the middle, which applies to the drilling of cast iron, carbon steel, copper, aluminum alloy, alloy steel, etc. The product combines the process of drilling, boring and broaching in one step, making holes of high accuracy(IT6-8 level), precise straightness(0.16-0.33mm/1000mm) and low toughness in one time feeding(Ra3.2-Ra0.1). The drilling speed can reach 30-100meter/minute or above. The hard alloy drill gun (depth drill) is an ideal hole finishing tool with its head adopting the entire hard alloy or empiecement structure, featuring high durability and high precision. With the dimensional precision of the processed hole being up to H7, and good straightness<0.1/1000mm, roundness≤0.005mm and surface roughness≤Ra0.8um, the product has been extensively applied in industries such as the machine tool, automobiles, aviation, motor locomotive, chemical machinery, oil nozzles and pumps, mining machinery, hydraulic parts, etc. Bangyu series drill guns can be used on the equipment which meets the requirements for drill gun cooling and direction guiding such as the special deep-hole processing machine, processing center, turning center, etc. and can be used for the processing of carbon steel, stainless steel, cast iron, non-ferrous metal, as well as wood and plastics. Bangyu company will provide customers with the optimized cutting technology parameters according to their machine tool conditions to ensure the best cutting performance of drill guns. To ensure drill guns' long-term, smooth and reliable working performance, the company supplies with the drill gun the integrated rough/finishing diamond grinding12A2/45° wheels which will enable the rough grinding and finishing grinding to be achieved by one time loading of the drill gun so as to greatly improve the efficiency and quality of the grinding process. We ensure the processing property and quality of the grinded drill guns close to that of new ones. We ensure the smooth drilling of drill guns.
