Frequently Asked Questions

Does this jig work with carbide and HSS jointer knives?

Yes. The strong rare-earth magnets securely hold both carbide-tipped and HSS (high-speed steel) jointer knives in place. Browse compatible planer and jointer knives.

What length knives does this jig fit?

It works with jointer knives from 4" to 8" long on any conventional cutterhead.

How accurate is the knife setup?

The jig lets you achieve a coplanar setup to within .002" across the full length of the knife, giving you a smoother, more accurate cut.

How does the magnetic jig save time?

The powerful magnets hold each knife in perfect position, freeing both hands so you can tighten the jib nuts without the knife shifting. This jointer setup tool removes the guesswork from resetting knives.

Can it help me get more life out of nicked knives?

Yes. The jig lets you shift nicked knives sideways while maintaining accuracy, so a fresh section of edge does the cutting. This extends the usable life of your knives.

Is the jig made of plastic or metal?

It is built from premium steel, not plastic, with precision-machined brass bars and ground, polished rods for years of service.

Will it work on my jointer's cutterhead?

Yes. The jig is designed to work with knives on any conventional cutterhead. Pair it with quality jointer knives for best results.

What holds the knives in position during setup?

Extra-strong rare-earth magnets secure either carbide or HSS knives firmly in place while you set them and tighten the jib nuts.

Why should I bother setting jointer knives accurately?

Misaligned knives leave ridges and snipe in your boards. Accurate, coplanar setup produces a smoother, flatter surface and reduces sanding. See more setup and measuring tools.

Is this jig a good investment for a hobby jointer?

If you own a jointer, yes. By extending knife life and improving cut quality, it pays for itself over time. Explore more shop hand tools to round out your setup.
