The material can be saved and the power consumption of the machine can be reduced. When it is necessary to remove the sample from the material center for performance inspection, the sleeve drill cannot be replaced by other cutting tools. The sleeve drill is usually used to process holes over 60 mm in diameter, with a depth of more than ten meters. There are two kinds of casing drill: outer chip discharge and inner chip discharge (see deep hole drill). The main advantage of the outboard chipset drill is that the cutting fluid system is simple, but the diameter of the drill pipe is small, so the strength and rigidity of the drill pipe is poor, and it is mostly used in the small batch production of the single piece, and the inner chip discharge sleeve drill depends on the pressure of the cutting fluid. The chip is flushed out from the drill pipe, so it needs to be equipped with more complicated liquid supply system and solve the sealing problem, but the productivity is high, so it is suitable for batch production. The sleeve drill may have one or more high speed steel or cemented carbide cutters fitted with guide blocks to prevent vibration during cutting and to reduce the deflection of holes. The guide block is made of hard metal, Bakelite or nylon. Knife body and tubular drill pipe can be welded or special square thread connection. In order to ensure that the chip discharge is smooth and the cutting load is reduced, the blade of each head of the sleeve drill is designed into different shapes, so that the chip is narrower, and at the same time, there is a chip breaking table on the front of each cutter tooth, which makes the chip break. For large diameter blind hole jackets, special cutting device is needed to separate the core from the body.
