A REAMER OF ASYMMETRIC CONSTRUCTION

PURPOSE: An asymmetric reamer is provided to smoothly perform a cutting operation since the clearance angle of a tip is maintained to be smaller than that of a flute, so friction decreases in a reaming operation. CONSTITUTION: An asymmetric reamer comprises a plurality of cutting edges on a flute(10...

Zusammenfassung:	PURPOSE: An asymmetric reamer is provided to smoothly perform a cutting operation since the clearance angle of a tip is maintained to be smaller than that of a flute, so friction decreases in a reaming operation. CONSTITUTION: An asymmetric reamer comprises a plurality of cutting edges on a flute(10). Splitting angles(31~36) of the cutting edges are maintained within a range of given angles. The cutting edges have variation of pitches in an axial direction. Splitting angles of 58°, 60°, 62° are sequentially arranged based on six blades.
