Finish Reamers are used for final chambering when only a few chambers are needed, while Roughers save wear on Finish Reamers during multiple chamber cuts.
These reamers are made to SAAMI specifications, with options for Rougher and Finisher, featuring right-hand cutting, straight flutes, and solid pilots with integral throats.
