37" 20 HP 3-Phase Double Head Wide-Belt Sander | Grizzly H2934


H2934 37" 20 HP 3-Phase Double Head Wide-Belt Sander

Rarely can a machine claim to cut your sanding time in half.

The G0447 37" 20 HP 3-Phase Double Head Wide-Belt Sander features dual heads enabling them to sand to finer grits in a single pass!

The first belt runs on a single drum and the rear belt runs on a platen system which allows you to adjust the sanding depth.

The digital readout displays the table height in increments of 0.005" for super-accurate results.

The feed rate is easily adjusted by turning the feed rate dial on the feed belt gear box.

The amperage draw meter, located above the control panel, monitors the amperage draw on the machine while performing sanding operations.

For a full range of replacement belts for the H2934, 

If you are still sanding through two different grit levels using a single head wide-belt sander you are not being the most efficient.

Like all of the Grizzly wide-belt sanders, the H2934 comes with a 1-year warranty covering parts and assuring the unit is free from factory defects. (Consumables are not covered by the warranty.)

The H2934 manual was written by our U.S. based Technical Documentation Department and is packed with useful information. The complete and easy-to-read manual makes it easier to assemble and maintain your sander.

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