Solid carbide router bit

This solid carbide router bit is designed for routing operations in hard plastic materials. The upcut O-flute spiral geometry promotes efficient chip evacuation during cutting. It features a 3/16 inch cutting diameter suited for precision milling tasks.

Machinists working with hard plastics

The tool suits CNC operators and fabricators who need clean cuts in hard plastic sheet or block stock. It is not intended for metalworking, wood routing or composite materials that require different flute geometries.

3/16 inch cutting diameter

The 3/16 inch cutter diameter determines the minimum groove width and internal corner radius achievable. Verify that this dimension matches the feature sizes required by your part drawings before purchasing.

Questions about this item

How do I choose between the 3/16 inch and 3/8 inch cutter diameters for my application?

Select the 3/16 inch cutter for finer detail work in hard plastics and the 3/8 inch cutter when you need faster material removal on larger profiles.

What does the upcut O-flute geometry actually do when the bit is in the router?

The upcut spiral pulls chips upward and out of the cut, preventing re-welding in hard plastics while the O-flute shape reduces heat buildup.

How does the solid carbide construction affect performance on a standard router?

Carbide retains its edge far longer than high-speed steel, allowing higher feed rates in hard plastics without frequent resharpening.
