Best Cordless Sander
As an Amazon Associate we earn from qualifying purchases.
The person typing best cordless sander wants a battery-powered sander that works with a battery they already own, so the first thing to check is the voltage or battery platform on each listing. This guide reads five Amazon listings from four brands and reports only what each page states: sander type, voltage, speed, battery status and any runtime figure. None of the listings ranks above another, and the sources we opened do not say which sander works best in use. Start with your battery, then match the sander type to your projects.
Quick answer
- Sander type: the CRAFTSMAN CMCW221B is listed as a detail sander. The other four listings describe random orbit sanders.
- Voltage: three listings state 20 volts, the FLEX lists 24 volts and the Makita lists 18 volts. Match this figure to the battery platform you own.
- Battery in the box: none of the five includes a battery. Four say the battery is sold separately or not included, and the CRAFTSMAN CMCW220B is titled Bare Tool Only.
- Runtime: only the FLEX (up to 30 minutes on Speed 3) and the Makita (up to 40 minutes on a single charge) state a figure, and the conditions behind them differ.
How the five sanders compare
The table uses only the figures each listing states. A cell says not stated where the page is silent.
| Sander (listing) | Type | Voltage | Speed (OPM) | Battery in the box | Runtime stated |
|---|---|---|---|---|---|
| CRAFTSMAN CMCW221B | Detail sander | 20 volts | 9,000 – 12,000 | No, battery sold separately | not stated |
| CRAFTSMAN CMCW220B | Random orbit, 5-inch | 20 volts | max 12,000 | No, bare tool only | not stated |
| FLEX FX3411-Z | Random orbit, 5-inch | 24 volts | 13,000 (Turbo Mode) | No, battery and charger not included | up to 30 minutes on Speed 3 |
| DEWALT DCW210B | Random orbit, 5-inch | 20 volts | 8,000 to 12,000 | No, battery and charger sold separately | not stated |
| Makita XOB01Z | Random orbit, 5-inch | 18 volts | 7,000 / 9,500 / 11,000 | No, battery sold separately | up to 40 minutes on a single charge |
Speed range from stated figures
Speed range here means the top stated speed minus the bottom stated speed. It is a subtraction of two listing figures. It does not show how fast a sander removes material, because no listing states that.
| Sander (listing) | Stated speeds (OPM) | Range (top minus bottom) |
|---|---|---|
| CRAFTSMAN CMCW221B | 9,000 to 12,000 | 3,000 |
| CRAFTSMAN CMCW220B | max 12,000 | not stated |
| FLEX FX3411-Z | 13,000 (Turbo Mode) | not stated |
| DEWALT DCW210B | 8,000 to 12,000 | 4,000 |
| Makita XOB01Z | 7,000, 9,500 and 11,000 (three settings) | 4,000 |
The Makita listing names three settings, so the steps are 2,500 OPM from the first to the second and 1,500 OPM from the second to the third. The CRAFTSMAN CMCW220B and FLEX listings each give one number, a maximum rather than a range, so this table does not compute a span for them. The widest stated span is the DEWALT and the Makita at 4,000 OPM each, and the CRAFTSMAN CMCW221B has the narrowest at 3,000 OPM.
Battery and runtime as stated
Two listings state a runtime. The FLEX listing says up to 30 minutes of runtime in Speed 3, based on a 3.5 Ah Stacked Lithium battery that is sold separately. The Makita listing says up to 40 minutes of run time on a single charge, with the battery sold separately, and it does not name the battery. The two figures cannot be compared directly, because the battery and the speed setting are different or unnamed. The other three listings state no runtime at all.
The battery platform decides whether a sander fits what you own, and each listing names its own. The FLEX listing describes compatibility with all FLEX 24V batteries, chargers and tools. The CRAFTSMAN CMCW220B bullet says it is part of the V20 cordless system, and the CRAFTSMAN CMCW221B and CMCW220B both state 20 volts. The DEWALT listing names the 20V MAX platform, and the Makita listing names the 18V LXT Lithium-Ion platform. None of the five says that a battery from another line fits. If you own a battery from one of these lines, check its platform and voltage against the listing before you buy.

The five sanders
Each section gives the listing’s own description, a table of the figures the page states, and a note on when that listing points away from the sander. Product links appear for two of the five listings only.
CRAFTSMAN 20V MAX Cordless Detail Sander, Tool Only (CMCW221B)
The listing places this red CRAFTSMAN sander in the Detail Sanders category and describes it for detail sanding projects. Its description says the sander is VERSATRACK compatible and lets you control dust by using the included dust bag or the 1-1/4 in. vacuum connection. The listing also describes a D-handle grip for vertical sanding, which is a stated feature rather than a comparison with other models.
| Spec | What the listing says |
|---|---|
| Type | Detail sander (category: Detail Sanders) |
| Voltage | 20 volts |
| Speed | 9,000 – 12,000 OPM, variable |
| Grit type | Coarse |
| Dust collection | Dust bag and 1-1/4 in vacuum connection |
| Dimensions | 11.4 x 6.7 x 3.9 inches |
| Battery | Battery sold separately (description) |
| Weight and warranty | not stated |
Skip it if you need a 5-inch random orbit pad, since the listing describes a detail sander. Skip it also if you need a battery in the box, because the description says the battery is sold separately.
CRAFTSMAN V20 Orbital Sander, Cordless, 12,000 OPM, Bare Tool Only (CMCW220B)
This is a 5-inch cordless random orbit sander, and the listing says it is part of the V20 cordless system. The bullets describe a low profile design, a dust sealed switch and a dust bag with a connection to an 1-1/4 in. vac hose. The listing includes one dust bag and three papers, in 60, 80 and 120 grit. The description says the sander is suited to surface preparation, smoothing seams, and removing paint or varnish.
| Spec | What the listing says |
|---|---|
| Type | Random orbit sander, 5-inch |
| Voltage | 20 volts (V20 cordless system) |
| Speed | max 12,000 OPM |
| Grit type | Medium |
| Dimensions | 7.7 x 5.8 x 5.8 inches |
| Included | Dust bag, 60 grit, 80 grit and 120 grit paper |
| Battery | Bare tool only (title); battery not named in the bullets |
| Weight and motor | not stated |
| Warranty | warranty document linked on the page; term not stated in the captured text |
Skip it if you need a speed range, because the listing gives only a maximum of 12,000 OPM. Skip it also if you need a battery in the box, since the title says Bare Tool Only.
FLEX 24V Brushless Cordless 5-Inch 13,000 OPM Random Orbital Sander, Tool Only (FX3411-Z)
This FLEX sander is a 5-inch random orbital sander on 24 volts. The listing describes Turbo Mode at 13,000 OPM, a sensor-free brushless motor, and a pad brake. It also describes a dust and water-resistant switch and a low-profile design. The runtime line gives up to 30 minutes on Speed 3, based on a 3.5 Ah Stacked Lithium battery that is sold separately.
| Spec | What the listing says |
|---|---|
| Type | Random orbital sander, 5-inch |
| Voltage | 24 volts |
| Speed | 13,000 OPM (Turbo Mode, class-leading per the listing) |
| Motor | Sensor-free brushless |
| Grit type | Fine |
| Dimensions | 5.1 x 6.6 x 4.6 inches |
| Runtime | up to 30 minutes on Speed 3, based on a 3.5 Ah Stacked Lithium battery (sold separately) |
| Battery and charger | Not included (title) |
| Weight | not stated |
| Warranty | FLEX Limited Lifetime Warranty when registered within 30 days of purchase through December 31, 2025 |
Skip it if your batteries are not FLEX 24V, since the listing describes compatibility with FLEX 24V batteries, chargers and tools. The warranty line ties registration to a purchase window that ended on December 31, 2025, and the listing does not say whether the warranty applies to a purchase made now.
DEWALT 20V MAX Orbital Sander, Tool Only (DCW210B)
The DEWALT listing describes a 5-inch brushless cordless random orbital sander on the 20V MAX platform, with a variable-speed dial from 8,000 to 12,000 OPM. It describes a one-handed locking dust bag, an 8-hole hook-and-loop pad, and a rubber overmold grip. The description also says the bag can attach to the DWV010 or DWV012 dust collectors. The listing names replacement pad DWE64233 in its bullets.
| Spec | What the listing says |
|---|---|
| Type | Random orbit sander, 5-inch, brushless |
| Voltage | 20 volts (20V MAX) |
| Speed | 8,000 to 12,000 OPM, variable |
| Pad | 8-hole hook-and-loop, replacement DWE64233 (bullets) |
| Dust collection | One-handed locking dust bag; can attach to DWV010 or DWV012 dust collectors |
| Dimensions | 8.81 x 6.38 x 5.75 inches |
| Battery and charger | Sold separately (description) |
| Runtime, weight and warranty | not stated (a warranty document is linked on the page) |
Skip it if you need a battery and charger in the box, because the listing says both are sold separately. The listing also does not name the battery capacity it expects, so check the battery you plan to use against the listing before you buy.
Makita XOB01Z 18V LXT Lithium-Ion Cordless 5-inch Random Orbit Sander, Tool Only
The Makita listing describes a 5-inch random orbit sander on the 18V LXT Lithium-Ion platform, sold as a tool only. It has three speed settings, 7,000, 9,500 and 11,000 OPM, changed with a one-touch electronic switch. The description says the pad brake reduces free-spin and a control system regulates pad speed at start-up. It uses quick-change 8-hole hook-and-loop paper and gives up to 40 minutes of run time on a single charge, with the battery sold separately.
| Spec | What the listing says |
|---|---|
| Type | Random orbit sander, 5-inch |
| Voltage | 18 volts (18V LXT Lithium-Ion) |
| Speed | 7,000, 9,500 and 11,000 OPM (three settings) |
| Pad | 5-inch, 8-hole hook-and-loop |
| Dimensions | 12 x 12 x 12 inches, as the listing states |
| Runtime | up to 40 minutes on a single charge (battery sold separately) |
| Battery | Tool only (title); battery sold separately (description) |
| Weight, motor and warranty | not stated |
Skip it if you do not already own an 18V LXT battery, since the listing names only that platform and does not list other batteries that fit. The dimension line gives the same 12 inches for all three measurements, and the listing does not explain it.
How we chose
We started from the Amazon search for best cordless sander, read on 2026-10-22. The first results included cordless and corded sanders, sanding discs and sandpaper packs, and a few third-party sanders described as compatible with another brand’s battery. We left out the sandpaper packs, the corded DEWALT orbital sander kit shown in the results, and the third-party listings. We read five listings from four brands: two CRAFTSMAN, one FLEX, one DEWALT and one Makita. No earlier stored product records for these five ASINs were in the research folder, so every figure here comes from the pages we read on that date.
The criteria were three. The listing had to describe a battery-powered sander, it had to state a voltage or battery platform, and it had to be a sander the listing names by model. Tool-only listings were allowed, and we say so in each section. We did not rank the five, and we did not record prices, ratings or review text. Where a listing gives one figure for a spec, we report that figure and say whether it is a maximum or a range.
What we could not verify
- How any of the five sanders performs on a job. The sources state features and figures, and they do not report results.
- Runtime for the three listings that state none: the CRAFTSMAN CMCW221B, the CRAFTSMAN CMCW220B and the DEWALT DCW210B.
- Whether a battery from another brand fits any of these sanders. The listings name only their own platforms.
- How the OPM figures were obtained. None of the listings says.
- How much dust each system captures. The CRAFTSMAN CMCW220B bullets call its dust collection high performance, and the sources do not say how it compares with the others.
What the sources do not say
- Item weight for any of the five. None of the captured listing texts gives one.
- Motor type for three sanders. Only the FLEX and the DEWALT name a brushless motor.
- Warranty term for four sanders. Only the FLEX gives a term, and that term is tied to a registration date that ended on December 31, 2025.
- Which batteries of other brands fit the DEWALT or the Makita. The listings name a platform only.
- Why the Makita listing gives 12 inches for all three dimensions. The page states it as written and does not explain it.
Buying checklist
Use these checks on any listing, including the five above, before you compare the figures.
- Find the voltage and platform on the listing and match them to the battery you already own.
- Read the title for the words Tool Only, Bare Tool Only, or Battery Not Included, since they decide whether a battery is in the box.
- Confirm the sander type named in the title, such as detail or random orbit, and check that it matches the work you plan to do.
- Look for a speed range with a bottom figure. A single number is a maximum, and the listings do not say more.
- Check the runtime line for the battery it is based on and the speed setting it uses, before you compare it with another runtime.
- Check the warranty section for a term and any registration date attached to it.
Mistakes to avoid
- Assuming a battery is in the box. All five listings say it is not included, sold separately, or a bare tool.
- Reading the CRAFTSMAN CMCW220B maximum of 12,000 OPM as a full range. The listing gives only the maximum.
- Comparing the FLEX and Makita runtime figures as if they used the same battery. The FLEX names a 3.5 Ah battery at Speed 3, and the Makita does not name its battery.
- Treating the FLEX warranty as current. The listing ties it to registration through December 31, 2025.
FAQ
Which sander type should I choose, detail or random orbit?
The five listings split into one detail sander and four random orbit sanders. The CRAFTSMAN CMCW221B is in the Detail Sanders category and is described for detail sanding projects. The CRAFTSMAN CMCW220B description says its random orbit sander is suited to surface preparation, smoothing seams, and removing paint or varnish, and the other random orbit listings do not give a task list.
Does any of these sanders come with a battery?
No. Four listings say the battery is sold separately or not included, and the CRAFTSMAN CMCW220B is titled Bare Tool Only. The FLEX title also says the charger is not included, and the DEWALT listing says the battery and charger are sold separately.
Can I use a battery from another brand?
None of the five listings says that a battery from another brand fits. Each names its own platform: FLEX 24V, the CRAFTSMAN V20 system at 20 volts, the DEWALT 20V MAX platform, and the Makita 18V LXT Lithium-Ion platform. Check the platform and voltage on your battery against the listing before you buy.
How long does the battery last?
The FLEX listing says up to 30 minutes on Speed 3 with a 3.5 Ah Stacked Lithium battery. The Makita listing says up to 40 minutes on a single charge, without naming its battery. The other three listings state no runtime, so the sources do not give a like-for-like figure.
Which listing states the highest speed?
The FLEX listing states 13,000 OPM in Turbo Mode, which is the highest figure among the five. The CRAFTSMAN CMCW220B and the DEWALT DCW210B each state a maximum of 12,000 OPM, the CRAFTSMAN CMCW221B states a range up to 12,000 OPM, and the Makita states a top setting of 11,000 OPM.
Do the listings state weight or warranty?
No item weight appears in the captured text for any of the five. The FLEX listing gives a limited lifetime warranty tied to registration through December 31, 2025. The CRAFTSMAN CMCW220B and the DEWALT DCW210B link to a warranty document but do not give a term in the captured text.
Bottom line
Decision rule: find the battery platform and voltage you already own, keep only the listings that name that platform, and then choose the detail or random orbit type that matches your work. If a listing does not name your platform, do not assume the battery fits.
