Solid Carbide Router Bit

The Onsrud 63-726 is a solid carbide routing end mill with an upcut O-flute spiral. It is manufactured for machining hard plastic materials where chip evacuation and a clean finish are required. The tool is supplied new and ready for use in compatible routing equipment.

Suitable Applications

This bit suits operators cutting hard plastics who need upward chip removal to keep the work area clear. It is not intended for metal, wood or soft plastic work where a different flute geometry or cutter material would perform better. Buyers who need a downcut action or a larger cutting diameter should look at alternative tooling.

1/4 Inch Cutter Diameter

The cutting diameter is 1/4 inch, which determines the minimum internal radius and the width of the slot this tool can produce. Verify that your machine collet accepts this shank size and that the programmed toolpath matches the diameter before ordering.

Questions about this item

How does the 1/4 in cutter diameter limit feed rate under sustained use?

The 1/4 in cutter diameter restricts chip clearance, so feed rate must stay low to avoid clogging during long routing passes.

Does the upcut O-flute design increase heat or noise during all-day operation?

Upcut action pulls chips upward, reducing heat buildup in hard plastic, but the spiral flutes produce a steady high-pitched whine at full speed.

What shank size must the router collet accept for this bit to work?

The bit requires a 1/4 in collet; verify your router includes or can accept that shank diameter before purchasing.
