Their thickness is in the range of 12-50, with a length of 600-1000. The dimensions of standard SDS-Max indicate that this tool is designed for deep hole drilling. Drills with a larger diameter are used to equip technical communications. Each diameter is directly dependent on length.ĭrill bits less than 12 mm are used to create holes in fixing systems. You can find drills thickness of 4 or 5 mm but finding an appropriate tool is very difficult.

SDS plus drill bits have only even diameters, with a minimum of 6 mm and a maximum of 26 mm. High strength and an optimal sharpening angle make it possible to grind even metal rods as well as to minimize uncertainties.Ĭlassification of drill bits by diameters Such drill bits are used for processing reinforced concrete. The structure of its tip is more complex than in the previous case, however impact load is distributed evenly. Thanks to some research it has become possible to create a drill bit with a tetrahedral and even hexagonal working head. Such a tool cannot cope with high-strength concrete. However, during drilling a large uncertainty in diameter is observed, while the drill bit heats up and loses its original quality. Most large drills have a head in the form of a shovel with equal edges, which are sharpened at an angle of more than 90 degrees. SDS plus shanks are installed on core drill bits or bore bits with a diameter of 26 mm. The thickness of SDS plus drill bits is almost half that of Max ones.

There are differences between them, for example, the first has five grooves, and the second has four. There are five types of SDS shanks, however, only two of them have gained popularity: SDS max and SDS plus.

They have several grooves designed to transmit shock vibration effectively as well as rotation. The main feature of drill bits is the shape of their shanks. Modern technologies make it possible to produce inserts from the improved tungsten-cobalt alloy. The main material for production of carbide inserts is the alloy based on tungsten and cobalt. Peculiarities of SDS plus drill bits for concrete The cutting surface of such a product has reverse sharpening. For these purposes, drill bits for concrete are improved with cemented metal carbide tips. As a result, a tool for drilling must possess enhanced technical characteristics. The drill bit 8x250x310 mm is designed to drill holes in unreinforced concrete, brick, sand and gravel mix and other Ĭoncrete is one of the most durable materials, therefore it is very difficult to drill even the smallest hole in it.
