Turning and grooving tools are used with lathes to remove sections of material or add grooves to workpieces. Cut-off blades cut radially into the end of a workpiece to reduce its length. Grooving tools cut channels on the end of a workpiece (face grooving) or in an existing bore (internal grooving). Grooving tool sets include multiple tools, each with a different-sized shank or cutting tip.
