Who It's For
A true 4-row helical head and the widest tables in this group at 9 inches. It sits between the G0490X and the G0858, and the trade you're making is dovetail ways instead of parallelogram beds. Needs a dedicated 230V circuit.
What Owners Praise
- A genuine 4-row helical head that shears rather than chops, with test cuts showing no ridging or scalloping
- At 9 inches these are the widest tables in this group
- Much quieter than the straight-knife jointers owners traded in
- The built-in mobile base works well, and five spare inserts come in the box
What Owners Report as Limitations
- It uses dovetail ways rather than parallelogram beds, and owners report table alignment being tedious as a result
- At 450 pounds it's the lightest of the 8-inch floor machines here and gets described as top-heavy
- Some owners think the fit and finish falls short for the money
Upgrades & Compatibility
Replacement inserts are Grizzly H9893, ten to a pack, and the machine ships with five spares already. The mobile base is included. If table alignment matters to you more than anything, the parallelogram G0858 is the machine to compare against.
Alternatives to Consider
-
The G0858 is an 8-inch parallelogram jointer with the same helical head and 3 HP, adding parallelogram bed adjustment over the G0856's dovetail ways.
Compare with Grizzly G0858 -
The G0490X is an 8-inch parallelogram jointer with a spiral cutterhead and heavier build, a step up in adjustability and mass at a higher price.
Compare with Grizzly G0490x -
The South Bend SB1091 is a professional-grade 8-inch parallelogram with a helical head, a substantially heavier, higher-end machine for demanding use.
