The Onsrud 67-200 Series Upcut is a high-performance, solid carbide router bit for abrasive composites.
Known as a "Phenolic Specialist," this Onsrud tool is trusted for dense laminates and reinforced plastics.
It is built for demanding CNC routing where edge quality, heat control, and tool life matter.
Its free-cutting action supports cleaner results across difficult sheet goods and resin-heavy panels.
As an Upcut design, it helps move chips away from the cut for more consistent routing.
Onsrud 67-200 Series Upcut Features
  • Three-Flute Design: Balances high feed rates with a smooth finish. It helps reduce tool pressure and heat buildup.
  • Chipbreaker Geometry: Breaks long chips into smaller particles. This can improve dust extraction and support a steadier cutting path.
  • Solid Carbide Construction: Manufactured from premium-grade carbide for rigidity and wear resistance in abrasive materials.
  • Acoustic Efficiency: Runs at lower noise levels than standard straight or spiral bits. That can make long production runs easier to manage.
Primary Applications
This series is optimized for high-pressure laminates and industrial composites, including:
  • Phenolics & Bakelite
  • G10 / FR4 / Garolite (Fiberglass-reinforced epoxy)
  • Trespa® and other HPL architectural panels
  • Micarta and similar resin-impregnated fabrics
These materials are known for abrasive fillers, dense resins, and surface brittleness.
A purpose-built cutter helps reduce edge damage and supports more predictable finished parts.
These Router Bits are suited to shops that need clean edges in hard, abrasive sheet materials.
Performance Benefits
The Onsrud 67-200 Series Upcut is preferred in the aerospace, marine, and electrical industries because it helps reduce delamination and fraying.
Whether cutting structural components or decorative panels, the Onsrud 67-200 Series Upcut delivers a clean, burr-free edge.
It also supports longer service life in demanding, abrasive materials and more repeatable output.
That means less time spent managing chipped edges and inconsistent finishes.
