Crown for perforator S2 Crown 125x100 S&R (209007482)

Description

The S & R hollow core bit is used for fast drilling of large diameter holes in concrete, masonry and natural stone. The S & R VERSIO core bit is used with: S & R VERSIO centering drill VERSIO extension. When performing drilling work, it is necessary to lubricate the tool shanks. When drilling holes to a depth of more than 450 mm using prefabricated systems, it is necessary to perform preliminary drilling with short-length drills to a depth of at least 150 mm, after which a longer tool should be used. This will not only protect the tool from breakage, but also increase the drilling speed, since the impact energy from the power tool used will be transmitted to the drill tip with minimal losses. As a result, drilling will be fast and accurate, and drilling will be as productive as possible due to the minimal manifestation of the vibration effect and the correct distribution of the impact energy of the power tool in the system. When drilling to a depth of more than 450 mm in the horizontal plane and especially the vertical plane in the downward direction, it is necessary to periodically make reverse movements along the incomplete withdrawal of the working tool from the hole in order to remove the accumulated slag in the hole. This will speed up the process of removing slag from the hole, and therefore increase the drilling productivity of the tool.
