Freud Straight Router Bit 11-158 3/8 Inch (1/2 Shank Single Flute Solid Carbide 1 Inch Cut Depth Wood Composite High Speed Chip Clearance Cutter)

Freud 11-158 3/8 Inch Single Flute Solid Carbide Straight Router Bit

The Freud 11-158 is a 3/8-inch cutting diameter single flute straight router bit engineered to execute rapid stock removal, high-speed grooving, and deep slotting in hardwoods, softwoods, plywood, and wood composites. Constructed entirely from Freud Premier Solid Carbide and fused to a rigid 1/2-inch steel shank, this high-production wood-milling bit maximizes chip ejection space to prevent thermal clogging at rotational speeds up to 24,000 RPM. Featuring a 1-inch carbide height and 3-inch overall length, it integrates directly with CNC machinery, table-mounted routers, and handheld power routers to increase feed rates while maintaining cool operation during heavy-duty cutting.

Best Used For:

• High-Speed CNC Slotting & Dado Milling: Rapidly routing 3/8-inch wide grooves and dado channels in MDF, particle board, and plywood panels at elevated machine feed rates.
• Abrasive Composite Stock Removal: Clearing deep material pockets and roughing cutouts in dense hardwoods and composite sheets without heat pack-up.
• Deep Channel Chip-Free Routing: Executing long continuous slot cuts where rapid waste ejection is required to prevent bit binding and burning.

Key Performance & Safety Features

• Premier Solid Carbide Construction: Micro-grain solid carbide matrix provides superior structural hardness and long-lasting edge sharpness under heavy thermal loads.
• Single Flute High-Clearance Geometry: Open single-flute design delivers maximum gullet volume for instant chip ejection at high feed speeds.
• Heavy-Duty 1/2-Inch Steel Shank: Sized for maximum torsional strength to eliminate vibration and shank deflection in heavy CNC collets.
• Thermal Buildup Prevention: Rapid waste clearing reduces friction and prevents pitch buildup to preserve cutting edge integrity.
• Multi-Machine Equipment Utility: Fully rated and balanced for safe operation across CNC routers, router tables, and handheld routers.
• Substrate Cutting Range: Engineered to process clean hardwoods, softwoods, structural plywood, and abrasive synthetic composites.

Technical Specifications

Pro-Tip: Increase your CNC feed rate when using this single flute bit compared to standard double flute bits to ensure larger chip loading, which carries heat away from the cut face and prevents resin burning in composite materials.
