98 inserts over 20' to produce a silky-smooth finish.

The 4-row spiral cutterhead of the G0454Z 20' 5 HP Planer produces silky-smooth finishes and greatly reduces tearout in figured woods. The 98 indexable, German-made carbide insert cutters can each be rotated three times to expose new, sharp cutting edges.

The 5 HP motor spins the cutterhead at 4800 RPM to plane your stock up to 20' wide by 8' thick. It can cut as deep as 3/16' on a 6'-wide board.

Solid cast-iron and steel construction and large planing capacity make this planer a true heavyweight. With the built-in mobile base, you’ll be able to move this planer around your shop with ease.

The precision-ground cast-iron table and extension wings provide a lengthy 55-1/2' of support of your stock. The two-speed gear box offers feed rates of 16 FPM and 20 FPM for maximum versatility.

Like all Grizzly planers, the G0454Z comes with a 1-year warranty which covers parts and assures the unit is free from factory defects. (Consumables are not covered by the warranty.)

The G0454Z manual was written by our U.S. based Technical Documentation Department and is packed with useful information.

The Grizzly Customer Service and Technical Support Teams are U.S. based. Parts for the planer may be available online and shipped from the Grizzly parts warehouse in Springfield, MO.
