Eyryfui 1/4" Compression Spiral Flush Trim Router Bit – DLC Coated Solid Carbide
Achieve flawless, splinter‑free edges with the Eyryfui Compression Spiral Flush Trim Bit. Engineered for woodworkers and CNC users, this bit combines a precision bottom bearing with up‑and‑down cut geometry to eliminate tear‑out on both top and bottom surfaces—minimizing sanding and rework.
Precision Construction
Crafted from solid tungsten carbide with a DLC (Diamond‑Like Carbon) coating, this bit reduces friction and heat buildup, delivering smoother cuts in hardwoods, plywood, MDF, and plastics. The 1/4" shank fits most handheld routers and CNC machines for maximum versatility.
Optimized Cutting Parameters
For best results, match your router settings to the material:
Softwoods (Pine, Cedar): 18,000–24,000 RPM | 100–150 IPM feed rate
Hardwoods (Oak, Maple, Walnut): 14,000–18,000 RPM | 60–100 IPM feed rate
Plywood / MDF / Composites: 16,000–20,000 RPM | 80–120 IPM feed rate
Plastics / Acrylic: 12,000–16,000 RPM | 50–80 IPM feed rate
If burning occurs, reduce RPM or increase feed rate. Smaller diameter bits tolerate higher RPMs than larger bits.
Ideal Applications
Perfect for flush trimming laminate, veneer, and edge banding; template and pattern routing; CNC milling; window cutouts; and craft projects.
Material Compatibility
Works exceptionally well on hardwoods, softwoods, plywood, MDF, particleboard, composites, and plastics.
Not for use on metals, stone, tile, or glass. Avoid aggressive single‑pass cuts in thick hardwoods—use multiple shallow passes to prevent overload and extend bit life.
Safety & Best Practices
Always inspect the bearing before use. Secure your workpiece and template firmly. Ensure the router collet is clean, undamaged, and properly tightened. Wear eye and ear protection, and keep hands clear of the cutting area.
