These reamers can create threads (M2-M7), (M3-M12) and (M8-M20), depending on the selection. They feature torque adjustment capability (with numerical scale) to prevent reamer breakage. They are equipped with an anti-vibration clutch, which has a unique design with double springs. This mechanism allows automatic disengagement during clockwise (CW) rotation and smooth engagement during counterclockwise (CCW) rotation. The counterclockwise movement withdraws the reamer faster than the clockwise, significantly increasing productivity. The taper in the head uses round, flexible collets for size adjustment and concentric alignment of the reamer. The rear square end of the reamer (shank) is held by a self-centering two-jaw clamping plate, which provides the main drive to the reamer during operation.
