DeWalt DCW210 vs Milwaukee M18 random orbit sander

The short answer: DeWalt for weight, Milwaukee for warranty and dust gear

Two pro-brand sanders at the same price, with different strengths.

• The DeWalt DCW210B is best for long sanding sessions, where its 1.9 lb listed weight and brushless motor count most.
• The Milwaukee 2648-20 is best for buyers who want the longest warranty, the lowest speed setting and everything for dust collection in the box.
• Our pick with no platform constraint is the DeWalt, because weight in the hand matters more on a sander than on almost any other cordless tool.
• With a platform constraint, buy the one that matches your batteries. A second platform for one $149 tool is never the better deal.
• The disclaimer: figures come from DeWalt's and Milwaukee's pages and manuals and from Zoro's listings, read October 21, 2026. We did not sand with either.

Price: identical bare, so the battery decides

Zoro listed both tools at $149.00 bare on October 21, 2026. Neither maker publishes a price on its own product page.

At the same price, the real cost difference is the battery. A DeWalt owner pays $149 for the DCW210B. The same owner buying the Milwaukee also needs an M18 pack and charger, which turns a $149 decision into a platform decision.

For a buyer with no batteries, both require a pack and charger on top, and both cost more than Ryobi's PCL406K1 kit at $124.00 with a 4Ah battery included. Read the Ryobi ONE+ random orbit sander review if that is you.

Our Milwaukee M18 vs DeWalt 20V comparison covers the platform choice across drills and drivers.

Handling: the DeWalt is 0.8 lb lighter and 1.7 in. shorter

On listed figures, the DeWalt weighs 1.9 lb and the Milwaukee 2.7 lb. Both are sold bare, so we read both as weights without a battery.

The DeWalt is also shorter, 8.8 in. against 10.5 in., and slightly taller, 5.8 in. against 5.74 in. The Milwaukee is narrower, 4.92 in. against 6.4 in.

On a sander, weight is held for the whole job, often at arm's length on a vertical surface. A third more mass is noticeable over an hour. DeWalt markets its low profile for control close to the work.

The battery adds to both. The pack you fit will change the balance more than the tool body, so compare with your usual pack attached if you can.

Speed: the Milwaukee reaches 1,000 OPM lower

Both top out at 12,000 orbits per minute. The Milwaukee's dial starts at 7,000 and the DeWalt's at 8,000.

The low end matters for finish work: scuffing between coats, sanding veneer, or working near an edge where a fast pad can round over a corner. A lower floor gives more margin.

The high end is identical, so stock removal at full speed should be comparable at the same grit, all else equal. Milwaukee publishes a 3/32 in. orbit; DeWalt does not publish one, which leaves the scratch pattern comparison incomplete.

For most homeowner sanding, both ranges are adequate. For fine finishing, the Milwaukee has the edge on paper.

Motor and runtime: DeWalt is brushless, Milwaukee publishes the number

DeWalt lists a brushless motor for the DCW210B. Milwaukee's specification table lists FUEL: No and Motor Type: Not Applicable for the 2648-20, so we do not describe it as brushless.

Brushless motors generally waste less energy as heat, which tends to mean more runtime per charge. DeWalt does not publish a runtime, so we cannot put a number on the advantage.

Milwaukee does publish one: up to 35 minutes on an M18 XC3.0 pack. That is a useful planning figure for a garage project.

Our battery label explainer shows how to scale that claim to a larger pack using watt-hours.

Dust collection: Milwaukee ships the adapters, DeWalt sells them

Dust is the part of sanding most likely to cause problems indoors, and the two makers handle it differently.

Milwaukee includes a dust canister with a filter, a universal hose adapter and an extension adapter in the box, per its product page. Most shop-vac hoses should connect on day one.

DeWalt includes a one-handed locking dust bag. Its port fits DeWalt's DWV010 and DWV012 extractors directly. For other vacuums with 1-1/4 in. hoses, DeWalt says to use the DWV9000 Universal Quick Connector, sold separately.

If you own a DeWalt extractor, the DeWalt is the tidier system. If you own a generic shop vac, the Milwaukee is ready out of the box.

Warranty: the Milwaukee covers two years longer

Milwaukee lists a 5-year limited warranty on the 2648-20. DeWalt lists a 3-year limited warranty, 1 year of free service and a 90-day satisfaction guarantee on the DCW210B.

The DeWalt terms are better in the first three months, when a money-back window lets you return a tool you do not like, and in the first year, when service is free. After year three, only the Milwaukee is covered.

For a tool you expect to keep a decade, the longer term is worth more. Both makers publish manuals and parts diagrams on the product page, and both run service-centre networks.

Owner ratings: DeWalt scores higher, Milwaukee has more reviews

On October 21, 2026, DeWalt's page showed 4.5 from 124 reviews and Milwaukee's showed 4.3 from 470.

Both are seller-hosted, which tends to inflate averages, and the two sites moderate differently. A 0.2-point gap across two sites is not strong evidence of a real difference.

We could not read retailer reviews for either tool, so owner feedback does not move the result here.

Safety: same rules for both

Milwaukee's manual asks for eye protection marked ANSI Z87.1 and, in dusty conditions, respiratory protection or an OSHA-compliant dust extraction solution. It also says to remove the battery before changing paper or emptying the canister.

Those rules apply equally to the DeWalt. Connect a vacuum indoors, wear a mask suited to the material, and check old paint for lead before sanding it. Read each maker's manual before first use.

Pads and paper: both 5 in. hook-and-loop, with different hole patterns to check

Both sanders use 5 in. hook-and-loop discs, so paper is easy to find for either.

DeWalt specifies an 8-hole pad, replaceable as part DWE64233, with a pressure-sensitive adhesive pad available as service part N373679. Its page links DeWalt's own 8-hole paper in 80 and 100 grit, 25 to a pack.

Milwaukee's manual says the holes in the disc must line up with the holes in the pad for dust collection to work, and explains a four-screw swap to an optional PSA pad. The box includes two sheets of 80 grit.

The practical rule is the same for both: buy paper whose hole pattern matches your pad, or the dust system works poorly.

In the box: what you still need before the first sanding job

Neither tool is ready to use out of the box, because both are sold bare.

• DeWalt DCW210B: sander and dust bag. Add a 20V MAX battery, a charger and paper. Add the DWV9000 connector if your vacuum is not a DeWalt DWV010 or DWV012.
• Milwaukee 2648-20: sander, dust canister, universal hose adapter, extension adapter and two 80-grit sheets. Add an M18 battery and charger, plus finer paper for finishing.
• For both: eye protection, a dust mask or respirator suited to the material, and ideally a vacuum hose for indoor work.

If neither fits: the cheaper and corded options

Two other routes are worth a look before spending $149 on a bare tool.

Ryobi's PCL406B lists at $59.97 bare and its PCL406K1 kit at $124.00 with a 4Ah battery and charger on ryobitools.com, checked October 21, 2026. It runs at a single listed 10,000 OPM with a 3/32 in. orbit and carries a 3-year warranty.

Ryobi also lists a corded 5 in. random orbit sander, the RS290G, at $69.00. A corded sander never runs out of charge, which suits long bench sessions near an outlet.

If you already own the Ryobi ONE+ drill, the cordless Ryobi is the obvious buy.

How we compared them

We read each maker's product page, specification table and manual on October 21, 2026, and took bare prices from Zoro the same day, because neither maker publishes one. Home Depot and Lowe's blocked automated access that day.

Where one maker publishes a figure and the other does not, such as orbit diameter or runtime, we report the gap rather than estimating the missing number.

Scores use the four pillars on every review on this site: ease, features, value and support. We did not sand with either tool.

Job by job: which spec matters where

Mapping each sander's published figures to common homeowner jobs makes the trade-offs concrete.

• Refinishing a dresser or table: long sessions on flat tops favour the DeWalt's 1.9 lb listed weight; the Milwaukee's 7,000 OPM floor helps on veneer edges.
• Scuffing cabinet doors between paint coats: low speed and fine paper matter most, which favours the Milwaukee's wider dial.
• Sanding a deck rail or fence outdoors: dust matters less and runtime more; only Milwaukee publishes a figure, up to 35 minutes on an XC3.0 pack.
• Overhead or vertical work, such as a door frame: every ounce counts, which favours the DeWalt.
• Indoor work with a generic shop vac: the Milwaukee connects with the included adapter; the DeWalt needs the DWV9000 connector.

Choose the DeWalt if, choose the Milwaukee if

One question settles most cases: which batteries do you own?

• Choose the DeWalt DCW210B if you own DeWalt 20V MAX packs, for example from the DeWalt 20V drill driver or the DeWalt DCS570 circular saw. Read the full DeWalt DCW210 review.
• Choose the DeWalt if you have no platform, sand for long sessions and value weight and a brushless motor most.
• Choose the Milwaukee 2648-20 if you own M18 packs, for example from the M18 FUEL drill and impact combo. Read the full Milwaukee M18 sander review.
• Choose the Milwaukee if you want a 5-year warranty, a 7,000 OPM low setting and a hose adapter in the box.
• Choose neither if you sand a few times a year and own no batteries. The Ryobi PCL406K1 kit is $124.00 with a battery and charger.

Where this fits in a tool kit

Most homeowners buy a sander after a drill and a saw. Our first power tools for homeowners guide explains that order and why the first battery platform shapes the rest.

For corners and profiles a 5 in. pad cannot reach, the Dremel 4300 rotary tool takes small sanding drums and flap wheels.

Bottom line

At the same $149 bare price, the DeWalt DCW210B and the Milwaukee 2648-20 split the field: the DeWalt is lighter, shorter and brushless; the Milwaukee has the longer warranty, the wider speed range, a published runtime and complete dust gear in the box.

We pick the DeWalt for a buyer with no platform, because comfort over a long session is what a sander is judged on. For everyone else, buy the one that takes the batteries you already own.
