Maximize Production Speed and Chip Clearance with the Freud 3/8 Inch Single Flute Straight Router Bit

Optimize your high-production workflow with the Freud 11-158 3/8 Inch Single Flute Straight Bit. Designed specifically for fast feed rates and efficiency, this bit features a single flute geometry that provides maximum space for chip ejection. This design is crucial when working at high speeds, as it prevents chip clogging and reduces heat buildup, ensuring a cooler cut and extending the life of the tool. It is the ideal choice for rapid stock removal and general-purpose routing where speed is a priority.

Constructed from Freud's Premier Solid Carbide, this bit offers superior hardness and edge retention compared to standard steel cutters. The robust 1/2-inch shank provides the stability needed to minimize vibration during heavy-duty cutting. Whether you are operating a high-speed CNC machine, a table-mounted router, or a hand-held tool, this bit delivers consistent performance in hardwood, softwood, plywood, and composite materials.

Key Features

  • High-Production Design: Single flute geometry allows for faster feed rates and increased productivity.
  • Maximum Chip Clearance: Open flute design ejects debris rapidly to prevent clogging and overheating.
  • Premier Solid Carbide: Micro-grain carbide construction ensures a sharper edge and longer tool life.
  • Versatile Compatibility: Engineered for use on CNC, hand-held, and table-mounted routers.
  • Heavy-Duty Shank: 1/2-inch shank diameter offers excellent stability and reduces chatter.
  • Multi-Material Cutting: Effective in hardwood, softwood, plywood, and various composites.

Pro-Tip: Single flute bits are excellent for plunge cuts and drilling applications because the single flute allows significantly more room for waste material to escape upwards. This prevents the "burning" often seen when trying to plunge with double or triple flute bits.
