The high-quality bi-metal hole saw creates holes with a diameter of 51 mm quickly and reliably. The precise cutting action is convincing in many applications in industry and trade and leaves nothing to be desired. Even in hard materials, the metal hole saw cuts its way purposefully and powerfully. The hole saw is made from durable HSS bi-metal M42. The material withstands even the highest loads. Even heat, which typically occurs during drilling, cannot harm the metal alloy. This means that the bi-metal hole cutter effortlessly cuts even stainless steel, steel, wood with nails, hardwood or even plastic. This wide range of different materials means that the metal hole saw can be used effectively for a wide variety of applications. The design of the milling teeth has been optimally developed for drilling in which the drilling chips need to be removed immediately during drilling. The variable toothing with 4 to 6 teeth per inch also ensures low-vibration drilling that produces a uniform cutting edge. For the bi-metal hole saw you need a holder (not included in the scope of delivery) with which you can use it with commercially available electric or compressed air drills with a shank size of 13 mm. Likewise, the hole cutter can be used with a fixed pillar drilling machine. We recommend the model with the item number 10061800 from MSW, which you can also purchase at expondo.
