This article provides a comprehensive list of replacement knives, inserts, and cutterhead upgrade options for various jointer and planer machine models, including Grizzly and compatible non-Grizzly brands. Users can select their machine model and find compatible parts with direct product links. It also covers aftermarket cutterhead inserts for upgraded machines. Compatibility depends on model numbers, manufacture dates, and serial ranges.

Looking for replacement knives or inserts for your jointer or planer or considering a cutterhead upgrade? You’re in the right place.

Start by selecting your machine model number from the list below. Be sure to note any manufacture dates or serial number ranges shown, as these determine compatibility.

Pro tip: Use Ctrl + F to quickly find your model.

What you’ll find in this list

Replacement straight knives or carbide inserts that fit the original cutterhead your machine came with
Compatible spiral or helical cutterhead upgrade options, when available for that model

All listed knives, inserts, and cutterheads link directly to their product pages for easy ordering. If your model does not show any replacement options, that means we don’t currently stock them; however, the listed size specifications can help you source compatible parts elsewhere.

Have a Non-Grizzly Brand?

We have several compatible cutterheads for your non-Grizzly branded machines! If you'd like to check on available options, please click HERE to jump to that section.
