Featuring a top-of-the-line helical cutterhead for smooth cutting and fine finishes, the Powermatic 15HH 15-Inch Planer is ideal for precision wood dimensioning. Accurate and dependable, this planer's powerful motor, smooth feeds, precise depth-of-cut adjustments, robust construction, and integrated dust hood set a new standard in wood planing.

Byrd Helical Cutterhead for Smooth, Quiet Cuts
A top-of-the-line woodworking tool, the 15HH features Tom Byrd's famous helical cutterhead. The Byrd cutterhead is made from stress-proof steel for unrivaled durability, and it is ultra-efficient thanks to 74 carbide inserts that are arranged in spiral-shaped rows. These inserts have a four-inch radius ground into them and are mounted to approach your workpiece at a 14-degree angle, so you'll get a true shear cut every time you use it.While the 15HH is capable of 3/16-inch-deep cuts on most stock widths, a limiter plate at the center of the cutterhead limits full-width cuts to 1/8 inch or less. This helps avoid applying excessive strain on the machine and prevents damage to the wood.
To top it off, the Byrd cutterhead is incredibly quiet. In fact, you may not realize it's cutting wood until you see the remarkable results!
Powerful Motor for Reliable Performances
The 15HH owes its robust performance to a three-horsepower (continuous duty rating), single-phase, 230-volt TEFC (totally enclosed fan-cooled) motor. This motor is mounted in the planer's base cabinet, and it is operated by a true magnetic switch located on the head assembly. For trouble-free maintenance, the motor features an easily removable, full-length belt cover.
Smooth Infeeds and Outfeeds
The 15HH features a serrated steel infeed roller and a smooth steel outfeed roller that allow for positive feeding and non-marring of the wood upon exit.
What's more, the 15HH has two material feed rates: 20 FPM used primarily for rough dimensioning and 16 FPM used primarily for smooth dimensioning. The two-speed gearbox features an automatic chain tensioner and a push/pull knob makes shifting between feed rates as easy as can be.
Durable, Adjustable, and Maneuverable
The 15-HH's tables are made of cast iron with smooth, precision-ground surfaces for durability and easy feeds. Measuring 15 inches wide by 20 inches long, the main table provides ample space for larger projects. A pair of cast-iron extension tables (15.75-inches wide by 14 inches long), means you can expand the table to 48 inches in length.
A large cast-iron handwheel positions the table quickly and easily, and four posts give you optimum stability. And built around a fully enclosed welded steel base cabinet, the 15HH features machined iron casters that ensure durability and maneuverability--a foot-operated brake lets you lock the casters into place.
Dust Hood Deflects Debris away from Your Workpiece
To help protect components and improve visibility, an all-metal dust hood diverts debris from the cutterhead. The hood terminates with a four-inch diameter port that is conveniently angled to the side, so the dust collector hose does not interfere with the exiting stock.
Dimensions and Warranty Information
The 15HH measures approximately 48.0 x 28.0 x 43.5 inches (WxHxD), weighs 502 pounds, and is backed by a five-year warranty.

Helical cutterhead on this planer provides smoother cutting and a finer finish than conventional knives and the 98 four-sided indexable carbide knife inserts do not require adjustment after installing. Three V-belts transfer maximum power from the 3HP motor to the cutterhead. Your workpiece will get substantial support from the precision ground cast iron table and two large extension wings. The 4-Inch dust port angles the collection hose away from the work area. Stock return rollers atop the machine speed repetitive cuts. The serrated steel infeed and smooth steel outfeed roller allow for 1/8-Inch maximum depth of cut and trouble-free operation. A 2-speed gearbox features an automatic chain tensioner. The one-piece welded steel stand has built-in lockable casters fro easy movement around the shop.
