Experience Superior Stock Removal and Smooth Finishes

Maximize precision and efficiency in your shop with the Freud 12-106T 5/16" Double Flute Straight Router Bit. This versatile industrial-grade tool is the workhorse of any woodworking operation, designed to handle a wide array of tasks from cutting crisp dadoes and rabbets to routing precise mortises and edges. Whether you are crafting cabinetry, furniture, or joinery, the computer-balanced double flute geometry ensures fast chip clearance and a perfectly smooth surface finish that requires little to no sanding.

Engineered for durability under heavy workloads, this bit features Freud’s exclusive TiCo™ Hi-Density Carbide. This specialized micrograin formula is specifically designed to retain a razor-sharp edge longer than standard bits, even when cutting through abrasive materials like plywood, composites, and dense hardwoods. The bit tips are end-relieved to facilitate smooth plunge cuts, making it ideal for stopped grooves. Protected by Freud’s Red Perma-SHIELD® Non-Stick Coating, the tool resists heat buildup, corrosion, and pitch accumulation, ensuring reliable performance in CNC, hand-held, and table-mounted routers.

Key Features

  • Double Flute Geometry: Ensures balanced cutting and superior surface finish on all materials.
  • TiCo™ Hi-Density Carbide: Proprietary blend delivers maximum cutting life and extended sharpness.
  • Perma-SHIELD® Coating: Non-stick red coating reduces friction, prevents rust, and resists resin buildup.
  • End-Relieved Tips: Allows for efficient and clean plunge cutting for mortising applications.
  • Versatile Application: Perfect for grooving, edge-routing, dadoing, and general stock removal.
  • Wide Compatibility: Engineered for safe use on CNC, hand-held, and table-mounted routers.
  • Heavy-Duty Shank: 1/2" shank provides maximum stability and minimizes vibration.

Pro-Tip: The 5/16" diameter is often used for specific spline joinery or shelving grooves. When cutting deep slots, avoid attempting to cut the full depth in one pass, as this traps chips and overheats the carbide. Instead, perform multiple passes, increasing the depth by approximately 1/4" to 5/16" with each pass, to maintain a cooler bit and a cleaner edge.
