Five Features of a Double-Edged Straight Groove Knife
A double-edged straight groove knife uses two opposing cutting edges to share the cutting load and remove material efficiently. Its straight flutes form clean vertical groove walls, while the flat-bottom geometry produces a level channel floor. The sharp entry profile supports accurate starts and detailed slotting. This cutter is useful for grooves, lettering, outlines, pockets, and joinery in wood, plastics, acrylic, and other suitable materials.
Select the cutting diameter, flute length, shank size, point or entry angle, cutter material, and coating for the groove width and depth. Accurate tool holding, low runout, suitable spindle speed, controlled feed, shallow step-down, and effective chip removal help prevent burning, vibration, and uneven edge wear. Inspect both cutting edges before machining. Correct setup improves groove accuracy, bottom finish, productivity, and cutter life in end milling.
