Who It's For
Eight inches of cut width on a bench, which is the main reason to pick this over a 6-inch machine. The tables pull out to 52 inches, so it handles longer stock than its footprint suggests. A good fit if your shop is a garage and a floor jointer isn't happening.
What Owners Praise
- You get 8-inch capacity without giving up floor space, and that's the whole pitch
- Built-in extensions take support from 34 inches to 52, which owners say makes a real difference on edges
- The 4-inch dust port collects far better than the 2-1/2 inch port on the 6-inch models
- Spiral inserts cut cleanly and quietly on figured stock
What Owners Report as Limitations
- Snipe at the ends of boards comes up regularly in owner reports
- Squaring the fence is fiddly and the aluminum fence can deflect under load
- Tables are cast aluminum rather than iron, and at 50 pounds it needs securing to the bench
Upgrades & Compatibility
It takes the same Grizzly T32739 inserts as the 6-inch models, around forty dollars for ten. There's no cutterhead upgrade to make since the insert head is already fitted. The next real step is a cast-iron floor machine.
Alternatives to Consider
-
The WEN JT833H is another 8-inch spiral benchtop with an extendable table, a close competitor that adds infeed and outfeed length, often at a lower price.
Compare with Wen Jt833h -
The G0986 steps up to a 10-inch spiral benchtop with a bit more power, giving you wider capacity if you routinely joint boards over 8 inches.
Compare with Grizzly G0986 -
The G0946 is the smaller 6-inch spiral benchtop in the same family, a cheaper, lighter choice if 8-inch capacity is more than you need.
