Onsrud 63-525 Solid Carbide Router Bit

The Onsrud 63-525 is a solid carbide router bit with a 1/4 inch cutter diameter and O-flute upcut spiral. It is designed for milling acrylic and similar plastics, delivering a clean plunge cut and efficient chip evacuation for CNC operators and fabricators.

Check collet size and material compatibility

Verify that your router or CNC spindle accepts a 1/4 inch shank before ordering. The bit is specified for acrylic applications; confirm that your workpiece material matches this primary use to avoid premature wear or poor cut quality.

California Proposition 65 notice included

Questions about this item

What comes with the Onsrud 63-525 bit and what must I buy separately?

The box contains the solid carbide router bit itself; you must supply a compatible 1/4 in collet or chuck and a router or CNC spindle to drive it.

How do I choose between the available versions of the 63-525?

Only the 63-525 model is listed, so there are no alternate versions or capacities to select from.

What does the upcut O-flute geometry mean when the bit is cutting acrylic?

The upcut spiral pulls chips upward and out of the cut, reducing heat buildup and leaving a cleaner edge in acrylic sheet.
