Irregularly-Spaced Flutes

Irregular spacing is a standard feature of all METCUT oil-feed reamers. This type of spacing provides a controlled cutting action that resists chatter and the formation of "welts." This flute spacing design, combined with the oil-feed and controlled sharpening features allows these reamers to produce surface finishes which do not require additional finishing operations. The teeth are spaced diametrically opposite each other for easy and accurate size verification.
