Precision Cutting with Onsrud 63-700 Series Router Bits

The LMT Onsrud 63-700 Series Solid Carbide Upcut Spiral O Flute Router Bit is specifically engineered for clean, accurate cutting in hard plastics and solid surface materials. Whether you're running a production CNC job or crafting custom components, this bit delivers superior results thanks to its high-performance design and premium materials.

The upcut spiral flute geometry ensures smooth chip removal in an upward direction, reducing heat buildup and providing a clean edge finish. It's a go-to bit for machinists and fabricators working with solid surface plastic (SSP) and hard plastic (HP).

Designed for Smooth Finishes in Plastics and Composites

When working with acrylics, polycarbonates, or solid surface materials like Corian®, you need a bit that won't melt the material, leave burrs, or clog with chips. The Onsrud 63-700 Series addresses these challenges with its O flute design, which allows for effective chip evacuation, cooler cutting, and reduced friction.

✅ Ideal for use in:

  • Hard plastics (HP)

  • Solid surface materials (SSP)

  • Cast acrylic

  • HDPE, PVC, ABS

  • Thermoplastics

  • Composite panels

Whether you’re creating intricate signage or shaping custom counters and enclosures, this bit provides the finish quality needed for professional-grade results.

Features and Benefits

  • Solid Carbide Construction: Provides durability, long tool life, and high-speed performance under tough conditions.

  • Spiral O Flute Geometry: Excellent chip clearance for plastics and composites.

  • Upcut Design: Pulls chips upward and away from the cutting surface, preventing heat buildup and material distortion.

  • Polished Cutting Edge: Reduces material drag and ensures a mirror-smooth edge finish on plastic surfaces.

  • Ideal for CNC Routers: Optimized for high-speed operations in commercial and industrial CNC environments.

Why Choose the Onsrud 63-700 Series?
