Smooth cutting, low vibration, high durability, good reaming quality, can be used to process holes with intermittent surfaces, such as keyway holes, can avoid reamer being stuck and prevent the teeth from chipping. Right-hand reamer is used for processing blind holes, cutting can be discharged along the groove, left-hand reamer axial force pointing to the shank, so that the clamping is secure, the cutting flow to the direction of the surface to be processed, applicable to the processing of through-hole.
