Frequently Asked Questions

Is this router bit compatible with Origin?

Yes, this bit will fit the ¼” collet that is supplied with Origin.

How deep can I cut in one pass?

As a general rule of thumb for cutting wood, it’s best to never cut deeper than the diameter of the bit. So for a ⅛” bit, you should not cut deeper than ⅛” in a single pass. Because every material is different, it’s best to perform test cuts to find the ideal pass depth and cut specs when working with a new material.

What is the best spindle speed, feed rate, and plunge rate for this router bit?

This depends on the material you are cutting. You can find more information on recommended settings for Origin based on material types in this article: material recommendations.

Will this bit leave tear-out on my material surface?

The up-spiral design pulls material up and out of your cuts. This can leave a little fuzz on the top edge of your material but this is easily removed with a quick rough-up with fine grit sandpaper. Adjacent spoilboards are always recommended when making cuts beyond the edge of your material.

What is the maximum cutting depth for this bit?

The ⅛” up-spiral router bit can cut to a maximum depth of ½".

How can I maintain my cutters?

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.
