摩氏锥孔铰刀是精加工摩氏锥孔的刀具。为了把原来钻削的直孔改成锥孔,并达到一定的精度和表面光泽度的要求,摩氏锥孔铰刀都是成组使用的。一组共有粗、中、细三把铰刀,各有不同的设计特点和使用要求。摩氏锥孔粗铰刀的主要作用,是将直孔改变成锥孔,加工余量较大,所以齿数不能太多,要便于出屑及修磨,并且要有足够的强度。它的齿背是铲制的, Mohs cone reamer is a tool for finishing Moxa cone. In order to change the original straight hole drilled tapered bore, and to achieve a certain degree of precision and surface gloss requirements, Morrison cone reamers are used in groups. A total of coarse, medium and fine reamers, each with different design features and requirements. The main role of Morris cone reamer is to change the straight hole into a tapered hole, the machining allowance is larger, so the number of teeth can not be too much, to facilitate the chip and grinding, and to have sufficient strength. Its back is shoveling,
