In the following slides we present the most common and costeffective router bit options based on application.For straight cuts such as sizing, jointing, rebating, grooving anddados, the options available are solid carbide, carbide insert orPCD (polycrystalline diamond).For profile routing applications, options are either carbide insertor PCD and for proto-type or“one-off”needs, a corrugated headprovides a cost-effective solution.In addition to the many standard tool designs, it is oftennecessary to customize a tool for a particular requirement inorder to provide a more economical option over time.Many tools styles can effortlessly produce the same cut, soresearching cost, time and yield based on tool choice can have asubstantial impact on a tooling budget.

1-800-544-8436Solid carbide router bits come in a variety of tool geometries, number of flutes, and edge grind to include the most popular ones below and described in more detail on the following pages.•O-Flute, Straight (Soft Wood/Soft Plastic)•O-Flute, Up Cut (Plastics, Aluminum)•Up Cut •Ball Nose Up cut•Down Cut•Compression (Mortise Compression)•Compression Chip Breaker•Up Cut Chip Breaker•Down Cut Chip Breaker•Up Cut Rougher•Down Cut Rougher•Single, Two and Three FlutesSOLID CARBIDE BITSRemember: More flutes doesnot equal better finish!More flutes means you have faster feed rate capability! Refer to the chip load information later in this presentation to calculate your needs.
1-800-544-8436O-FLUTE BIT (SOLID CARBIDE)This image shows a solid carbide, straight O-Flute. The flute shape is ground into what lookslike a half-circle.Thisparticulargeometryisusedforcuttingflexible plastics.The flute is straight and helpskeep a light weight flexible plastic from moving orlifting on the router table during machining.Use this tool on materials such as:PolycarbonateABSPolystyrenePVCand other flexible plastics

1-800-544-8436O-FLUTE UPCUTThe O-Flute upcut bit features the same O-Flutegeometry needed for efficient chip removal whenrouting plastic, and also has an upward shearingangle to bring the chips out of the cut and providecleanest possible edge finish.This tool is the preferred router bit for hard andrigid plastic materials, such as:AcrylicsNylonsPlexiglassand other rigid plastics.
1-800-544-8436UPCUT SPIRALThe up cut spiral bit is used when getting the chipsout of the cut is critically important, or when thematerial is laminated or coated on one side only,and is being machined face down.This toolgeometry does present a risk that the top of thematerial being cut can chip or fray.This tool is a good choice for mortise and tenoncutting needs and also provides an excellent optionfor short runs on Corian or phenolic.(longer runsshould consider a PCD diamond bit as it is morecost-effective).
As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
