Whiteside Router Bits RD4125 Standard Spiral Bit with Down Cut Solid Carbide 3/8-Inch Cutting Diameter and 1 1/4-Inch Cutting Length

Spiral bits provide a shear cutting edge that leaves a smoother cut than standard router bits. The down cut spiral design provides the best top surface edges, ejecting chips away from the router when routing through material. This design also decreases the tendency to lift thin/small work pieces during CNC routing.

Product Features

  • TOOL SPECS: Solid carbide, downcut spiral with 3/8" cutting diameter, 3/8" shank, 1-1/4" cutting length, and 3" overall length for use in routers with a 3/8" collet.
  • DOWN CUT SPIRAL: Down Cut Spirals ensure a clean edge on the side of the material closest to the router. For clean, top edges in handheld routing or CNC applications.
  • HELIX: For shallow grooves, dados, and inlays with a handheld router. The spiral helix offers a shearing action for clean, crisp cuts while outperforming standard straight bits.
  • CLEAN FINISH: The downward cutting action eliminates tearout when cutting grooves, dados, slots, and pockets in veneer, laminates, and plywood for precise woodworking results.
  • Great for holding thin sheets or small pieces in place during CNC routing operations, ensuring precision and stability. Ejects chips away from the router when cutting through material.
