The utility model, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of six sword reamers, can solve the problems of the technologies described above completely.
The technical scheme solved the problems of the technologies described above is as follows:
A kind of six sword reamers, comprise handle of a knife, cutter neck and cutter head, described cutter neck one end is connected with handle of a knife, the other end is connected with cutter head, and arranging six cutting edges at equal intervals in described cutter head outside, is provided with chip area between described cutting edge, described cutting edge comprises conical section and straightway, described conical section is positioned at the front end of cutting edge, and the relief angle of described straightway is 8 ~ 12 °, and the relief angle of described conical section is 8 ~ 10 °.
The diameter of described handle of a knife is greater than the diameter of cutter neck.
The length of described handle of a knife is 20mm.
The diameter of described handle of a knife is 4.47 ~ 4.5mm.
Described handle of a knife, cutter neck and cutter head overall length are 50mm, and wherein cutter head is long is 17mm.
Further, the top edge of tapered portion of adjacent two cutting edges and the angle of the extended line of lower limb are 20 °.
The diameter of cutter neck is 3.7mm, and handle of a knife and cutter neck junction are provided with chamfering.
The utility model structure is simple, and when cutter head enters surface to be machined, the conical section of leading section has an effect for guiding to whole reamer, the line part of cutter head is accurately entered in the hole of surface to be machined, improves machining accuracy.
