Abstract

PURPOSE: To aim at a stabilized reamer processing by forming a nick on a cutting edge land with its left side inclining downward and its right side inclining upward against the axis at the top of the reamer after dividing unequally, using the opposing cutting edge as a point symmetry, the angle of the cutting edges adjoining each other.
CONSTITUTION: An even number of cutting edges 2 are to be provided on a blade portion with the respective opposing cutting edges 2 are their point symmetry. An angle 'a' between the respective cutting edges 2 adjoining each other is to be divided unequally and then a nick 4 is to be formed on a land 3 with the left side inclining downward and the right side inclining upward against the axis 5 at the tip of a reamer. The nick 4 burnishes the cutting surface like scouring with a file when a cutting object is cut with this reamer. The nick 4 also aims to radiate the cutting heat and reduce the cutting resistance so as to prevent disposition of the edge of the blade. A stabilized reamer processing is feasible with this reamer because the angle 'a' between the cutting edges 2 is divided unequally which serves to restrain the tools from resonating and chattering.
