Machine reamers
Machine reamers
Machine reamers are used for final machining of apertures. According to the gripping type, there may be parallel shank reamers, taper shank reamers and inserted-tooth shell reamers (used for installation on an indefinite simple male punch, predominantly for large size tools). Such machine reamers are fixed in special drill sleeves. Diameter of machine reamers: 3-10 mm.
