End Mill

摘要

The workpiece section (12) of the cutter (10) is integrally joined to the shaft section (14). The radius of the lower cutting edge is between one and two times the diameter (d1) of the imaginary circle for the tangent (30) at the rounded cutting edge (26). The lower cutting edge (24) starts at a distance of 0.1 to 0.2 times the value (d1) from the shaft axis. The face end of the cutter has at least one flat cutting edge, a rounded corner cutting edge and a peripheral cutting edge.
