G9740 20" 7-1/2 HP 3-Phase Planer

This 20" workhorse is a great investment.

The G9740 20" 7-1/2 HP 3-Phase Planer was built for extreme duty.

This machine is solidly built weighing a massive 1678 pounds, with power up/down control for the table and variable speed feed.

The bed rollers on this machine are power-driven and adjustable for height when planing rough cut lumber.

The segmented chip breakers combined with the 4 HSS knife cutterhead means you get the best possible finish.

Like all Grizzly planers, the G9740 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 G9740 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 and accessories for the planer are available on-line and shipped from the Grizzly parts warehouse in Springfield, MO.
