Powermatic Helical Head Planer
It was a little bit aggressive of me to buy this machine. I have never needed it, nor will I ever need it. Honestly. I definitely do need a planer, but this is legitimately a professional piece of equipment. And professional… I am not. But I bought it for half price from a little outfit that was going out of business, so necessary or not, at least I got a good deal. So I have it, and occasionally I even use it. But always for something far smaller than what it was designed for. Works great anyway.
The Powermatic 15HH is one of those machines that makes you feel slightly unworthy just standing near it. It hums with quiet authority—every part machined, balanced, and built to last longer than the building it sits in. When I first rolled it into the shop (after some creative swearing and a hand truck that’s still mad at me), I realized I’d crossed an invisible line between “guy with tools” and “guy who owns equipment.”
Truth be told, I don’t have the kind of workflow that justifies this planer. I’m not running a production shop or milling rough lumber by the truckload. Most of what I do could easily be handled by a benchtop unit. But there’s a deep, irrational joy in using something this overbuilt for small jobs. It’s like taking a freight train to the grocery store.
When I do use it, the results are undeniable. Feed in a warped or rough board, and what comes out the other side is glass. The helical cutterhead makes almost no tear-out, even on gnarly grain, and the finish is so smooth it feels sanded. It’s quiet—relatively speaking—and the chip ejection is strong enough to fill a dust collector in minutes. Every time I use it, I’m reminded that tools like this are built not for convenience, but for mastery.
Field Notes
Build & Performance
The 15HH is, by all measures, a tank. Cast-iron table, robust cutterhead assembly, and a 3HP motor that doesn’t blink at a full-width cut. The spiral cutterhead holds forty carbide inserts, each one rotatable to expose a fresh edge when dull. It’s a beautiful, slightly absurd system of redundancy—overkill in the best possible way.
Adjustment is straightforward but requires intention. The feed rollers are heavy and positive, and the bed height crank feels like you’re dialing in a milling machine, not a woodworking tool. The digital readout is accurate to the thousandth, which is laughable for the kind of rough boards I’m usually running through it, but comforting nonetheless. Everything about this planer feels engineered to remind you that precision is possible—if you care enough to pursue it.
Dust collection is the only area where you can’t cut corners. This machine produces a storm of chips, and a full-sized collector is mandatory. Even then, you’ll be cleaning up curls from places you didn’t think physics would allow. It’s part of the charm, really—a reminder that woodworking is equal parts art and entropy.
