3/16 in Carbide Up Spiral O-Flute Router Bit
This solid carbide router bit features an up-spiral O-flute geometry designed for routing aluminium and similar non-ferrous materials. The 3/16 inch cutting diameter provides precise material removal in CNC and hand-held routing applications. Its uncoated carbide construction resists wear during extended cutting cycles.
Best for aluminium routing, not for ferrous metals
Machinists and fabricators cutting aluminium sheet, extrusion or plate will benefit from the O-flute upcut action that evacuates chips efficiently. Shops primarily working with steel, stainless steel or titanium should select a tool with a different geometry and coating suited to those materials. The bit is also unsuitable for wood or composite routing where a different flute profile performs better.
3/16 inch cutting diameter decides fit
The cutter diameter of 3/16 inch determines whether this bit matches the required slot width, hole size or profile radius in your programme. Verify the programmed tool path and machine collet capacity against this dimension before purchase. No other specification overrides this single fit-critical measurement.

Questions about this item
What collet size do I need to hold the 3/16 in shank on my router?
Use a 3/16 in collet or an adapter that grips the 3/16 in shank securely; the bit will not seat properly in a 1/4 in or 1/2 in collet without the correct sleeve.
Will this O-flute upcut bit clear chips effectively in the aluminum I already machine with standard straight flutes?
The O-flute upcut geometry is designed to evacuate chips upward in aluminum, reducing recutting and heat buildup compared with conventional straight-flute bits.
How can I verify the 63-618 is cutting cleanly after installation?
Inspect the aluminum edge for a smooth, burr-free finish and listen for a steady, quiet cut; excessive vibration or rough edges indicate improper feed, speed, or collet grip.
