Achieve Clean, Precise Grooves with Industrial-Grade Straight Bit Performance

Unlock the full potential of your woodworking projects with the Freud 12-108T 3/8" Double Flute Straight Router Bit. As one of the most versatile tools in any shop, this heavy-duty bit is engineered for general-purpose routing tasks ranging from cutting dadoes and rabbets to routing mortises and crisp edges. Whether you are working with solid hardwood, softwood, plywood, or abrasive composites, the sheer cutting angle design ensures rapid stock removal while leaving a smooth, splinter-free finish that requires minimal sanding.

Built for endurance and precision, the 12-108T features Freud's exclusive TiCo™ Hi-Density Carbide. This specialized micrograin formula is designed to stay sharper longer, maintaining a superior cutting edge even under the stress of high-volume production. The tips are end-relieved, allowing for efficient plunge cutting, making it an excellent choice for blind mortises and stopped grooves. Coated with Freud’s signature Red Perma-SHIELD® Non-Stick Coating, the bit resists heat buildup, corrosion, and pitch accumulation, ensuring smooth operation in CNC, hand-held, and table-mounted routers.

Key Features

  • Precision Ground Flutes: Double flute design provides a balanced cut and superior surface finish.
  • 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: Designed for efficient and smooth plunge cutting into material surfaces.
  • Versatile Application: Ideal for grooving, dadoing, rabbeting, mortising, and edge trimming.
  • Universal Compatibility: Engineered for use on CNC, hand-held, and table-mounted routers.
  • Heavy-Duty Shank: 1/2" shank offers maximum stability and reduced vibration during heavy cuts.

Pro-Tip: When cutting deep grooves or mortises, never try to cut the full depth in a single pass. To extend the life of your bit and prevent burning the wood, take multiple passes, cutting no deeper than the diameter of the bit (3/8") per pass. This allows for better chip evacuation and a cleaner final result.
