Experience Superior Stability and Deep Cutting Precision with the Freud 1/2 Inch Straight Router Bit

Achieve exceptionally clean, deep grooves and precise joinery with the Freud 12-122T 1/2 Inch Double Flute Straight Bit. Featuring a substantial 1-1/2 inch cutting length, this tool is engineered for deep routing tasks such as mortising for tenons, cutting deep dados, or edge trimming thick stock. The bit is anchored by a heavy-duty 1/2-inch shank, which provides the rigidity needed to minimize vibration and chatter, ensuring a flawless finish even during heavy material removal. Protected by Freud's signature red Perma-SHIELD coating, the cutter resists heat buildup, gumming, and corrosion, allowing for smoother operation and extended tool life.

Designed for versatility across all workshop setups, the 12-122T excels in CNC machinery, table-mounted routers, and hand-held routers. Its computer-balanced double flute geometry utilizes precise hook and shear angles to slice cleanly through hardwood, softwood, plywood, and abrasive composites, leaving a smooth surface that reduces the need for sanding. The bit also features end-relieved tips, allowing for efficient plunge cutting to start blind grooves or pockets anywhere on the workpiece. Whether you are a professional cabinet maker or a dedicated hobbyist, this bit delivers the reliability and accuracy required for high-quality woodworking.

Key Features

  • Deep Cutting Capacity: 1-1/2 inch carbide height allows for deep mortising, grooving, and edge trimming.
  • Perma-SHIELD Coating: Non-stick red coating reduces drag, prevents heat buildup, and resists pitch and resin.
  • Heavy-Duty Shank: 1/2-inch shank diameter ensures maximum stability and reduced vibration during cuts.
  • Double Flute Geometry: Two precision-ground edges provide a balance of fast chip removal and smooth finish.
  • Plunge Ready: Relieved tips allow for vertical drilling and starting cuts in the center of the material.
  • Versatile Application: Ideal for cutting wood, plywood, and composites in CNC, hand-held, or table routers.
  • TiCo Hi-Density Carbide: Freud's proprietary carbide blend maximizes sharpness and edge retention.

Pro-Tip: When using a bit with a long cutting length like this (1-1/2"), it is crucial to avoid cutting the full depth in a single pass. Deep single-pass cuts can cause the bit to deflect, resulting in a tapered or rough cut, and can overheat the carbide. For the best results and safety, make multiple passes of approximately 1/4" to 3/8" deep until you reach your final depth.
