Frequently Asked Questions

Is this router bit compatible with Origin?

Yes, this bit's shank will fit in Origin's 8 mm collet.

What is the maximum cutting depth?

The 4mm X 15mm Up-Spiral Flat Bit can cut to a maximum depth of 30 mm.

How can I maintain my bits?

Resin, sap, and adhesives will build up on your cutter edge over time. This generates more friction on your cutter and accelerates edge degradation. Keep your cutters clean with a small brass brush, citrus cleaner and a rag.
