Highlights

  • TOOL SPECS: Solid carbide, upcut spiral with 1/4" cutting diameter, 1/4" shank, 1" cutting length, and 2-1/2" overall length for use in routers with a 1/4" collet.
  • UP CUT SPIRAL: For smooth finishes and rapid chip removal. Up cut spirals create a clean edge on the side of the material that is farthest from the router.
  • HELIX: The upward cutting action removes chips efficiently, especially in deep cuts. The spiral helix ensures clean, crisp cuts while outperforming standard straight bits.
  • MULTI-PURPOSE TOOLING: Plunge-capable bit for precision woodworking. For creating grooves, dados, slots, pockets, and more.
  • MATERIALS: Performs best with hardwoods, softwoods, plywood, MDF, and hard plastics for woodworking applications.
