Best Cordless Caulk Gun
As an Amazon Associate we earn from qualifying purchases.
The best cordless caulk gun to begin with is the one that runs on a battery you already own. This guide reads nine battery-powered caulk gun listings from Amazon, opened on 2026-10-22. Three are DEWALT or Milwaukee guns, and six name a DeWalt, Milwaukee or Makita battery as compatible. Every listing is tool only, or says the battery is sold separately or not included, so check the battery model before you buy. The listings give speed, weight and kit figures, but none shows how a gun performs on a real caulk job.
Quick answer
- Match the battery first. The listings name DeWalt 20V MAX, Milwaukee M12 or 18V, and Makita 18V batteries. Confirm that your model appears on the page before you buy.
- Speed figures use different units. Three pages state 0 to 220 mm/min, two state 0 to 5.2 mm/sec (312 mm/min), two state 21 inches per minute (about 533 mm/min), and one states about 70 to 270 mm/min. Convert before you compare.
- Lowest stated weight: the winmitool at 2.24 pounds, with the APROTII at 2.25 pounds. Highest: the DEWALT DCE570B at 4.7 pounds.
- Two titles and their voltage fields disagree. The APROTII title says 18V and the winmitool title says 20V Max, but both Technical Details fields say 21 volts. Ask the seller or check the battery label.
What the nine listings state
The table uses each listing’s own wording, and says not stated where a page says nothing. The next section converts the speed units.
| Gun (ASIN) | Battery and charger | Battery named | Speed as stated | Item weight | Included |
|---|---|---|---|---|---|
| DEWALT DCE570B (B01J6KTDCK) | Tool only; battery and charger sold separately | 20V MAX* (title) | 21 inches per minute | 4.7 pounds | DCE560 Adhesive Gun (description) |
| DEWALT DCE560B (B01J6KTBI6) | Bare tool; battery sold separately | 20V MAX (title) | 21 in/min | 4.1 pounds | DCE560 Adhesive Gun (description) |
| Milwaukee 2441-20 (B00AAGVZVW) | Tool only (title) | M12 12V (title) | not stated | 4.1 pounds | not stated |
| RexLeLXB (B0D3CYBR39) | No battery | Milwaukee 18V model numbers (bullets) | 0 to 220 mm/min | 3.01 pounds | 3 scrapers, 4-piece scraper set, 1 through needle |
| APROTII (B0DP2ZDZW2) | No battery; bare tool only | Makita BL1815 to BL1860 (bullets) | 0 to 220 mm per minute | 2.25 pounds | 1 electric caulking gun, 1 manual |
| byczone (B0FY31P9KN) | Tool only; battery sold separately | DeWalt 20V Max system (bullets) | 0 to 5.2 mm/sec | 3.56 pounds | remover tool, 4 silicone pads, 3 nozzles |
| Funnywhale (B0FJ74BB7Q) | No battery; battery not included | DeWalt 20V MAX, six model numbers (bullets) | 0 to 220 MM/min | 3.63 pounds | 3 nozzle adapters, 5 knife heads, trowel and scraper tool |
| miduoduo (B0H9RCCQYY) | Tool only; battery sold separately | DeWalt 20V Max system (bullets) | 0 to 5.2 MM/sec | 1.52 kg | remover tool, 4 pads, 3 nozzles |
| winmitool (B0G3W3JB6N) | No battery; battery sold separately | DeWalt 20V Max system (bullets) | about 70 to 270 mm/min | 2.24 pounds | needle, caulk remover, 3 rubber heads, 5 pads, small brush, manual |
Stated figures, converted
The speed figures come in three units, and the weights come in pounds and kilograms. We convert each figure with a formula and leave the stated figure unchanged. Millimeters per minute equals the stated millimeters per second times 60. Inches per minute equals millimeters per minute divided by 25.4. Pounds equals kilograms times 2.2046.
| Gun | Speed as stated | Millimeters per minute | Inches per minute |
|---|---|---|---|
| DEWALT DCE570B and DCE560B | 21 in/min | 21 x 25.4 = 533 | 21 |
| byczone and miduoduo | 0 to 5.2 mm/sec (top figure) | 5.2 x 60 = 312 | 312 / 25.4 = 12.3 |
| RexLeLXB, APROTII and Funnywhale | 0 to 220 mm/min (top figure) | 220 | 220 / 25.4 = 8.7 |
| winmitool | about 70 to 270 mm/min | 70 to 270 | 2.8 to 10.6 |
| Milwaukee 2441-20 | not stated | not stated | not stated |
Taken at face value, 21 inches per minute is about 533 mm/min, roughly 2.4 times the 220 mm/min top figure on three other pages (533 divided by 220). The listings do not say how that figure was produced or what caulk it refers to.
The miduoduo page gives its weight only in kilograms. 1.52 kg times 2.2046 is 3.35 pounds, which sits between the RexLeLXB at 3.01 pounds and the byczone at 3.56 pounds. None of the pages says whether an item weight includes a battery.
The nine cordless caulk guns
Grouped by brand and battery platform, not ranked.
DEWALT DCE570B 29oz Cordless Caulking Gun (B01J6KTDCK)
The DCE570B is a DEWALT tool-only caulking gun with a 29oz capacity. Its bullets name a variable speed trigger and dial, an anti-drip feature that retracts the plunging rod, and interchangeable canister trays.
| Spec | What the listing says |
|---|---|
| Battery and charger | Sold separately (bullets) |
| Capacity | 29oz (title) |
| Speed | 21 inches per minute (bullets) |
| Item weight | 4.7 pounds (Item Weight); 4.66 pounds (bullets) |
| Power source | Cordless |
| Dimensions | not stated |
Skip it if you need a battery in the box. Its 4.7-pound item weight is the highest stated in this guide, and the page does not say whether that weight includes a battery.
DEWALT DCE560B 10oz Caulking Gun (B01J6KTBI6)
The DCE560B is the 10oz DEWALT gun, listed as a bare tool. Its bullets add an LED light and a hang hook to the same speed trigger, speed dial and anti-drip feature as the DCE570B, and say it is made in the USA with global materials.
| Spec | What the listing says |
|---|---|
| Battery | Bare tool; battery sold separately (description) |
| Battery named | 20V MAX (title); no model number stated |
| Cartridge | 10oz (title); 10oz/300ml (description) |
| Speed | 21 in/min (description) |
| Item weight | 4.1 pounds |
| Product dimensions | 21 inches long, 3 inches wide, 11 inches high |
| LED light and hang hook | Both listed (bullets) |
Skip it if you need a battery platform other than DeWalt 20V MAX, because the title names only that line. Only the DCE570B is heavier in this set.
Milwaukee 2441-20 M12 Caulk Gun (B00AAGVZVW)
The Milwaukee 2441-20 is the M12 gun in this guide. The title says tool only, and the page describes a cordless caulk and adhesive gun for standard 10 oz tubes. The page states no speed range and no drip feature.
| Spec | What the listing says |
|---|---|
| Battery platform | M12 12V (title and description) |
| Battery and charger | Tool only (title); no other battery line |
| Item weight | 4.1 pounds |
| Liquid volume | 10 fluid ounces |
| Surface recommendation | Counter Top, Door, Gutter, Pipe, Sink, Tile, Tub, Walls, Window |
| Water resistance | Not Water Resistant |
| Speed | not stated |
| Dimensions | not stated |
Skip it if you do not own M12 batteries, because the page names only the M12 platform. With no speed range stated, it cannot be set against the other pages.
RexLeLXB Cordless Caulking Gun for Milwaukee 18V (B0D3CYBR39)
The RexLeLXB gun comes with no battery. The listing names the RexLeLXB store, and its technical details name Shenzhen xun bao ke ji Co.,Ltd as manufacturer. The bullets list Milwaukee 18V model numbers, including 48-11-1811, 48-11-1850 and 2620, and say the gun is suitable for them.
| Spec | What the listing says |
|---|---|
| Battery and charger | No battery (title and bullets) |
| Battery named | Milwaukee 18V model numbers (bullets) |
| Speed | four gears, 0 to 220 mm/min |
| Cartridges | 10 oz and 300 ml |
| Light | 450lm work light (bullets) |

| Item weight | 3.01 pounds |
| Package dimensions | 16.02 x 9.09 x 3.11 inches |
| Included | 3 scrapers, 4-piece scraper set, 1 through needle |
Skip it if your battery is not on the Milwaukee 18V list, because the page names no other platform. Its bullets also describe a lock button that must be held while the lever is pulled out, so read that step before first use.
APROTII Electric Caulking Gun for 18V Makita (B0DP2ZDZW2)
The APROTII gun is a 10oz blue cordless gun sold with no battery or charger. The title says it fits an 18V Makita battery, and the bullets list six Makita model numbers from BL1815 to BL1860.
| Spec | What the listing says |
|---|---|
| Battery and charger | No battery included; bare tool only (bullets) |
| Battery named | Makita BL1830, BL1840, BL1850, BL1860, BL1820 and BL1815 (bullets) |
| Voltage | 21 volts (Technical Details); the title says 18V |
| Wattage | 42 watt-hours (Technical Details) |

| Product dimensions | 9.25 x 2.87 x 15.35 inches |
| Warranty | 3 Year (Warranty Description) |
| Included | 1 electric caulking gun, 1 manual |
Skip it if voltage matters to your purchase, since the page gives 18V in the title and 21 volts in its details without saying which applies. Skip it too if you want a battery and charger in the box.
byczone Electric Caulking Gun for DeWalt 20V Max (B0FY31P9KN)
The byczone gun is a yellow 10oz gun, described as tool only with the battery sold separately. The bullets name the DeWalt 20V Max battery system, six speed settings from 0 to 5.2 mm/sec, thrust of 800kg (±50kg), an LED light and an anti-drip system.
| Spec | What the listing says |

| Speed | six speed settings, 0 to 5.2 mm/sec |

| Voltage | not stated |

Skip it if you need a voltage figure, since the page states none, or a battery in the box. Its top speed of 5.2 mm/sec is about 12.3 inches per minute, well below the 21 inches per minute on the DEWALT pages.
Funnywhale Cordless Caulking Gun for DeWalt 20V MAX (B0FJ74BB7Q)
The Funnywhale gun is a 10oz yellow and black gun with no battery. Its bullets name six DeWalt 20V MAX models, DCB200, DCB201, DCB203, DCB204, DCB205 and DCB206, and state a 600KG push force, six gears from 0 to 220 MM/min, and an LED display of voltage and use time.
| Spec | What the listing says |
|---|---|
| Battery and charger | No battery; battery is not included (bullets) |

| Included | 3 nozzle adapters, 5 knife heads, trowel and scraper caulking tool |
Skip it if your DeWalt battery is not one of the six model numbers named, since the bullets list only those. The 600KG push force comes with no method given, so treat it as the seller’s figure.
miduoduo Cordless Electric Caulk Gun for DeWalt 20V (B0H9RCCQYY)
The miduoduo gun is a black 10oz tool-only gun with the battery sold separately, named for the DeWalt 20V Max battery system. The bullets state six speed settings from 0 to 5.2 mm/sec, thrust of 600kg (±50kg), and an anti-drip system.

| Voltage and dimensions | not stated |
| Included | Battery caulk gun, 3-in-1 silicone caulk remover tool, 4 replaceable silicone pads, 3 caulk nozzles |
Skip it if you need the weight in pounds on the page, since it gives kilograms only. The brand is miduoduo, but the page shows YETONG TOOLS as the seller, so check the seller before you buy.

The winmitool gun is a green 10oz cordless caulking gun with no battery. The bullets state stepless speed control at about 70 to 270 mm/min, a ring-shaped LED of about 450 lumens, and a built-in anti-drip mechanism.

How we chose
We began with the Amazon search for best cordless caulk gun, opened on 2026-10-22. It returned eleven product links. We read nine and left two out without opening, because their titles closely repeat a listing we did read.
The criteria were three: a cordless caulk gun for caulk or adhesive cartridges; a named battery platform or a tool-only status; and coverage of the three platforms the results showed, DeWalt, Milwaukee and Makita. All nine are battery-powered, so no substitute was needed, and manual caulk guns are outside this guide. Six listings say a battery from another brand is compatible. That wording is the seller’s, and none of the pages shows a battery maker’s approval. We did not rank the nine, and where a page gives two figures for one spec, both appear.
What we could not verify
- How any gun performs on a caulk or adhesive job. The pages give speed ranges, thrust and weight. None gives a flow rate for a named product or a drip figure.
- Whether the thrust figures can be compared. Four pages state thrust in kilograms (300KG, 600KG, 600kg and 800kg), and none says how it was produced.
- Which voltage applies to the APROTII and the winmitool, since each title and voltage field disagree.
- Runtime per battery charge. None of the nine listings states one.
- Whether a battery missing from a page’s model list fits the gun. No page says that every battery of its platform fits.
What the sources do not say
- Whether the Milwaukee 2441-20 includes a battery or charger. The title says tool only, and the page has no other battery line.
- Whether any item weight includes a battery. None of the pages says.
- Dimensions for the DCE570B, the Milwaukee 2441-20 and the miduoduo. Their pages give no dimension field.
- Warranty length for eight of the nine. Only the APROTII page gives one, a 3 Year Warranty Description; the others name no length.
- A speed range for the Milwaukee 2441-20.
- Whether DeWalt, Milwaukee or Makita approves any compatible gun. The compatibility wording belongs to each seller.
FAQ
Does a cordless caulk gun come with a battery?
None of the nine listings includes a battery. Each page says tool only, bare tool, no battery, or that the battery is sold separately, so budget for a battery and charger that match the gun.
Can a DeWalt battery run a Milwaukee gun?
These listings do not say so. The Milwaukee 2441-20 names only the M12 12V platform, and the RexLeLXB page names Milwaukee 18V model numbers. Check the model on the page before you buy, and do not assume a battery fits another brand’s gun. For a DeWalt battery in a different tool, see our guide to batteries for a DeWalt leaf blower.
How do I compare speed figures written in different units?
Convert them to one unit first. Millimeters per second times 60 gives millimeters per minute, and millimeters per minute divided by 25.4 gives inches per minute. The DEWALT pages state 21 inches per minute, about 533 mm/min, roughly 2.4 times the 220 mm/min top figure on three other pages. The pages do not say what each figure refers to.
Why do two listings state 21 volts when their titles say 18V or 20V?
The APROTII title says 18V Makita, and the winmitool title says 20V Max. Both Technical Details fields say 21 volts, and the pages do not explain the difference. Ask the seller or check the battery label before you buy. For how volts and amp-hours are written on a listing, see our lawn mower battery voltage and amp-hours guide.
Do these caulk guns have an anti-drip feature?
Eight of the nine pages say so, under names such as anti-drip, drip-free, no-drip or automatic retract. The Milwaukee 2441-20 page does not mention a drip feature. None of the pages gives a drip figure, so treat the claim as the seller’s.
Bottom line
Begin with the battery you already own, shortlist only the guns whose page names that battery platform or model, and compare speeds only after converting them to one unit.
