DeWalt 20V Max XR 3x21 Belt Sander vs Porter Cable 352: Cordless Finally Catches Up

Introduction

Belt sanders are the kind of tool that separates casual buyers from people who actually flatten tabletops and strip stock for a living. For years the corded camp had that market to itself, because no cordless sander could hold up to a heavy stock-removal session. DeWalt has now changed that with its first 20V Max XR 3x21 inch cordless belt sander, and the headline claim is a bold one: up to 22 percent more power than the long-standing corded Porter Cable 352.

That comparison is not accidental. Both brands sit under the same parent company, and the Porter Cable 352 has been the reference belt sander for a generation of woodworkers, even if it has become harder to find at major retailers. This guide walks through what each sander offers, where the cordless version pulls ahead, and what to check before spending your money.

DeWalt 20V Max XR 3x21: The First Cordless Entry

DeWalt describes this as an expansion of its existing cordless woodworking and carpentry range, and the brand has a strong track record to lean on. Its miter saws, table saws, orbital sanders, and sheet sanders have all earned a reputation for taking hard use, so a cordless belt sander fits a familiar pattern. The 3x21 inch belt size is the classic full-size format, which means you get a large sanding surface for flattening panels and heavy material removal.

Under the hood you get a brushless motor paired with DeWalt’s battery platform, and that is the whole story of modern cordless power tools: battery technology has reached the point where cordless tools are genuinely outperforming some corded ones. At 9.26 pounds the sander sits in the expected weight range for a full-size belt sander, and the over-molded auxiliary handle supports proper two-handed operation.

Speed control is generous. There are 25 speed increments running from 650 up to 1,050 feet per minute, so you can slow down to avoid burning a delicate workpiece or speed up to clear material fast. On top of that, a variable speed trigger gives you further modulation right where your hand is. Belt changes follow the familiar lever-release pattern: pop the lever out to loosen the belt, swap the sandpaper, and tighten it back down. That makes swaps quick and frustration-free.

Dust collection uses a tool-free dust chute with an adapter that connects to a standard 35 millimeter dust extractor, though that adapter is sold separately. The bare tool carries a three-year warranty and launched at $299 against a list price of $358. Early availability has been on back order with a three to five week shipping window, which suggests demand is strong and supply is still ramping up.

Porter Cable 352: The Corded Benchmark

The Porter Cable 352 is the corded 3x21 belt sander that many woodworkers grew up with. It built its reputation on straightforward, reliable stock removal and a simple plug-in-and-go workflow that never required a battery, a charger, or a charge-level check before starting a big glue-up job.

It is fair to say Porter Cable is not the brand it once was, and long-time fans have strong feelings about that. Availability has also thinned out, with the 352 no longer stocked at major home improvement chains like Lowe’s. Finding one today usually means hunting through smaller retailers or the used market, which is a real consideration if you want a new tool with full warranty coverage.

Power and Practicality Compared

The 22 percent power claim is the clearest headline: DeWalt says its cordless XR model delivers up to 22 percent more power than the Porter Cable 352. That would have sounded unrealistic a few years ago, but modern high-output battery packs have narrowed and in some cases reversed the gap between cordless and corded.

The practical differences go beyond raw power. The cordless version frees you from dragging a cord across your workpiece, tripping over it mid-pass, or sanding around a plug that only reaches so far. The corded 352, on the other hand, offers unlimited runtime without swapping packs, which still matters on marathon sanding sessions.

Buying Advice: Which One Fits Your Shop

If you already own DeWalt 20V Max batteries, the cordless XR sander is an easy recommendation. The $299 bare tool price stings less when you can slide in packs you already own, and the speed range, trigger control, and tool-free dust chute make it a genuinely modern take on the category. Just budget for the separately sold dust extractor adapter if you want dust collection dialed in, and expect a wait if stock is still on back order.

If you are strictly occasional-use or you find a well-priced 352 secondhand, the corded route still works. But for most woodworkers who want current availability, warranty support, and freedom of movement, the DeWalt is the safer long-term buy.

Conclusion

The DeWalt 20V Max XR 3x21 marks a genuine shift for belt sanders: a cordless full-size sander that claims to out-power a classic corded benchmark, with modern speed control and battery convenience on top. At $299 for the bare tool with a three-year warranty, it targets serious woodworkers rather than casual users, and the strong early demand suggests the market agrees. If you are building out a woodworking shop around a battery platform you already trust, this is the belt sander to watch.
