Glass-Filled PEEK Router Bits


Onsrud Router and Drill Bits Overview
What are Onsrud router bits?

Onsrud plastic router bits are designed for routing or cutting plastic materials at high speeds. Onsrud router bits are made out of solid carbide and are the industry standard for quality. Carbide router bits are harder and remain sharper for longer compared to high speed steel (HSS) bits when used for CNC routing. They provide superior cut quality and will wear out slower than HSS bits.


Customers Also Asked:
Can you use router bits on acrylic?

You can use router bits on acrylic. Onsrud acrylic and plexiglass router bits (CMD63) are specially designed to cut extruded and cast acrylic.

What router bit do I use to cut plexiglass?

Onsrud acrylic and plexiglass router bits (CMD63) are specially designed to cut plexiglass. Acrylic and plexiglass router bits from Onsrud tend to produce a smooth finish due to their unique cutting geometry, and work with both cast and extruded plexiglass/acrylic.

Can you use a router bit on plastic?

Router bits may be used on plastics - high speed steel (HSS) bits are recommended for hand operations, while carbide tipped bits are best used with more predictable controlled equipment such as a CNC router. Onsrud makes router bits for use with all types of plastic.

Which router bit stays sharp the longest?

Solid carbide bits are generally harder and stay sharper for longer than high speed steel bits in CNC routing scenarios. Onsrud specializes in carbide bits to ensure cut quality and bit longevity.


Choosing a Router Bit

When choosing a router bit for projects, consider the following:

  1. Router bits can cut a material as thick as the length of the flute.
  2. Router bits can drill a material as deep as the width of the flute, making multiple passes until the material is fully cut.
  3. Bit size is the full diameter and length of the bit. This is different from the flute size, which shows the depth and thickness of the cut.
