Hard Plastic Router Bits

Hard plastics — acrylic, Plexiglass, polycarbonate, PVC, HDPE, ABS, and polystyrene — cut differently than wood or aluminum. Run the wrong geometry and you get melted edges, chip welding, or stress cracks instead of a clean cut. This collection is solid carbide bits geared specifically for that material, with flute geometry designed to clear chips fast enough to keep heat from building up at the cutting edge.


These get used most in sign making, display fabrication, and general plastic processing — milling, engraving, and shaping work where the finished edge quality is part of the spec, not just a nice-to-have.


If you're cutting a hard plastic that's not listed here, let us know the material and thickness and we can point you to the right bit.

Onsrud 11-00 HSS Router Bit: Versatile Applications

The Onsrud 11-00 HSS Router Bit is expertly designed for use with both soft and hard plastics. Crafted from high-speed steel, it offers excellent durability and lasting performance during extensive use. Whether cutting soft plastic sheets or harder types of plastic, this router bit adjusts smoothly to fit your CNC routing tasks and requirements.

High-Speed Steel for Superior Performance

Produced from top-quality high-speed steel, the router bit retains its sharpness throughout prolonged use. This material is celebrated for its toughness and heat resistance. It enables the router bit to handle demanding routing without losing accuracy or harming the workpiece. This feature reduces downtime and the number of bit replacements needed by users.

Single and Double Flute Design Benefits

There are two flute styles available for this router bit: single and double flute. The single flute model suits faster feed rates and accelerates material removal during routing projects. Conversely, the double flute design achieves a finer surface finish on cut parts. This is suitable for work that requires enhanced surface quality and precision.

This router bit shines in the market because of the strong reputation of the Onsrud brand. Renowned for producing high-quality tooling, Onsrud offers precision-built router bits that satisfy professional and industrial standards. The 11-00 series blends strength and efficient cutting, all made possible by its high-speed steel construction.

  • Manufactured with durable HSS, delivering excellent resistance to wear and heat
  • Specifically designed for plastics, including both soft and hard types
  • Choices of single or double flute geometry to meet finishing requirements
  • Ideal for hand-fed CNC operations and helps decrease production time

Hand-Fed Operation Compatibility

A key highlight is the bit’s compatibility with hand-fed cutting systems. This feature suits smaller workshops or custom jobs needing manual router control. It ensures consistent cutting results even during hand-fed use, promoting superior workmanship and efficiency.

Safety and Efficiency of the Onsrud 11-00 HSS Router Bit

Using this router bit enhances safety during routing tasks. The high-speed steel material limits heat buildup, reducing risks of melting or warping sensitive plastic materials. Moreover, sharp cutting edges reduce the force needed, improving operator control and overall cutting precision.
