Onsrud 63-700 Series Solid Carbide Upcut Spiral O Flute Router Bit

$48.40

SKU: 63-701 LMT Onsrud

Precision Cutting Excellence: Onsrud 63-700 Series Router Bits

The Onsrud 63-700 Series delivers outstanding cutting results for professionals who need precision and reliability. This advanced router bit is crafted for sharp and smooth cuts in hard plastics as well as top-tier solid surface materials. Whether you're tackling high-volume CNC work or handling custom fabrication tasks, you get exceptional results due to its high-quality materials, thoughtful engineering, and robust design. The bit performs consistently even during demanding machining jobs, making it a staple for production environments and specialty shops alike.

Featuring an upcut spiral geometry, the bit ensures efficient chip removal throughout every pass. Chips are pulled upward and away from the workpiece, which reduces heat and minimizes friction. This maintains crisp, clean edges with less risk of melting or unsightly edge defects. Many fabricators choose this tool when working with hard plastics (HP) and solid surface plastics (SSP) to achieve precise, repeatable outcomes project after project. Superior chip evacuation also means less downtime for cleaning and maintenance.


Onsrud 63-700 Series: Smooth Results in Plastics and Composites

Are you working with acrylics, polycarbonates, or premium solid surfaces like Corian®? You need a bit that avoids melting, excessive burring, or chip clogging during cutting. The advanced O flute design used in the Onsrud 63-700 Series meets these requirements. This specialized flute geometry ensures chips leave the cut fast while keeping the cutting area cool, reducing friction that could degrade the finish or cause problems on the cut surface.

This LMT Onsrud router bit is perfect for professionals seeking flawless results on every pass. With less overheating, you’ll minimize the need for post-finishing work, saving both time and valuable materials. The polished flute delivers less resistance, allowing for fast, accurate machining, whether you’re handling prototypes or high-volume runs. Use this bit for fewer touchups and a reduction in material scrap across jobs.

✅ Ideal for use in:

  • Hard plastics (HP)
  • Solid surface materials (SSP)
  • Cast acrylic
  • HDPE, PVC, ABS
  • Thermoplastics
  • Composite panels

From creating detailed signage to shaping custom countertop edges and enclosure panels, this tool ensures a professional-grade finish for each job. An expert’s go-to for reliable results, it proves its value in every demanding fabrication environment.


Features and Benefits of an Advanced Router Bit Design

  • Solid Carbide Construction: High-strength material construction allows these bits to outlast competitors and remain sharp for longer—even when cutting tough plastics and composites.
  • Optimized Flute Geometry: Spiral flutes efficiently clear chips, reducing heat and preventing surface melting or deformation during demanding operations.
  • Upcut Design: The bit’s upcut motion extracts chips upward, ensuring cleaner cuts and protecting even delicate plastic edges from distortion or contaminants.
  • Polished Cutting Edge: Minimal resistance in the cut means surfaces are mirror-smooth with limited need for extra finishing processes, so you deliver premium jobs quickly.
  • Perfect for CNC Routers: Built for rapid, heavy-duty CNC applications, providing the durability and performance that busy shops demand every day.
