Pros

• 7-inch extended neck
• Five torque settings
• Seven sockets and tool bag

Cons

• Not made by DEWALT
• Longest body at 18 inches

Best for: DIYers wanting a simple bare-tool ratchet

Pros

• 74 ft-lbs brushless motor
• Aluminum alloy housing
• Two drive adapters included

Cons

• Not made by DEWALT
• No sockets in the box

The 3 8″ Cordless Ratchet Wrench with 74 ft-lbs of torque is a third-party tool sold under the ACROPOW name. Its listing states plainly that it is not manufactured by DEWALT and that it is tool only, with no battery or charger. It is built to take DEWALT 20V MAX batteries such as the DCB200 through DCB206.

A quick word on torque: ft-lbs (foot-pounds) measure twisting force. More torque helps break loose tight or rusted bolts. RPM measures how fast the head spins with no load. This ratchet gives 74 ft-lbs and 0 to 250 RPM from a brushless motor. It has an LED light, a low-profile head, an aluminum alloy housing to resist automotive oils and solvents, a rubberized grip, a variable speed trigger, a forward and reverse switch, and a safety trigger lock. The box adds a 3/8 to 1/2 inch adapter, a 3/8 to 1/4 inch adapter and a 3-inch extension bar, but no sockets. It is listed at 15.6 inches long.

This suits someone who already owns a socket set and DEWALT batteries and wants a basic, capable ratchet. If you need sockets in the box or more speed, the 88 ft-lbs model below includes both.

Cordless 3 8″ Ratchet Wrench

Best for: Car owners wanting metric sockets included

Pros

• 88 ft-lbs max torque
• Up to 500 RPM
• Five metric sockets and bag

Cons

• Not made by DEWALT
• Weight listed as 3 and 3.5 pounds

The Cordless 3 8″ Ratchet Wrench with 88 ft-lbs comes from VERVEWAVE, another third-party maker, and is compatible with a long list of DEWALT 20V MAX batteries. Battery and charger are not included. It pairs 88 ft-lbs with a 0 to 500 RPM variable speed trigger, the fastest listed here.

It has a brushless motor, a built-in LED and power indicator, an ultra-thin head for engine compartments and an insulated soft grip. The features say it weighs 3 pounds, while the specs list 3.5 pounds. The kit is generous: five metric sockets (13 to 17mm), 1/2 and 1/4 inch drive adapters, a 3-inch extension bar and a nylon bag.

This is a good fit for car owners who want a ready-to-use kit with metric sockets. If you would rather have the genuine brand with a warranty from DEWALT and a battery included, look at the DCF510GE1 next.

DEWALT 20V MAX XR Cordless Ratchet

Best for: Buyers who want genuine DEWALT with battery

Pros

• Swappable 3/8 and 1/2 inch anvils
• Sealed head design
• Battery and charger included

Cons

• Lower 0-300 RPM than some rivals
• No sockets listed

The DEWALT 20V MAX XR Cordless Ratchet set, model DCF510GE1, is the only DEWALT-made tool in this guide and the only one here that includes a battery and charger. Its standout feature is an interchangeable anvil: you can quickly swap between a 3/8 inch and a 1/2 inch square drive, so one tool works with both socket sizes.

The brushless motor delivers 75 ft-lbs of max torque and 0 to 300 RPM. It has a sealed head design and glass-filled nylon housing to help prevent damage from automotive oils and solvents, plus an LED light, a variable speed trigger, a forward and reverse switch and a trigger lock. It is listed at 15 inches long and 16 ounces.

Pick this one if you want the real DEWALT tool, especially as a gift for someone new to cordless tools who has no batteries yet. Its torque is similar to the third-party options, so if you already own batteries and just want more torque, the 88 or 89 ft-lbs models go further. For heavier fastening, see our DEWALT 1/2 ratchet guide.

The 3 8″ Cordless Ratchet Wrench Compatible with DEWALT 20V batteries is sold by Funnywhale, a third party, as tool only. Its standout is a 6.7-inch extended neck for deep or narrow spots like under the dashboard or deep in an engine bay. At 18 inches it is the longest tool here.

It delivers up to 80 ft-lbs and offers 5 torque settings (20, 45, 60, 70 and 80 ft-lbs), which help avoid over-tightening small bolts. It also has a forward and reverse switch, safety lock and LED light. The kit includes a 3/8 to 1/4 inch adapter, a 3-inch extension bar, 7 sockets and a tool bag. The listing does not specify speed.

This suits people working in awkward spaces. If you mostly work in open areas, a shorter model is easier to handle.

The 3 8″ Cordless Ratchet Wrench with 60 ft-lbs is a GOTUU tool, third-party and tool only. It has a brushless motor, up to 400 RPM, variable speed, a forward and reverse switch, a safety lock and an LED that turns on automatically.

The listing has two inconsistencies. The title mentions 8 sockets, while the included list names 6 (10 to 17mm). And the features say 60 ft-lbs while the specs say 60 in-lb, which would be a far smaller number. The kit also includes a 3/8 to 1/4 inch adapter, a 6-inch extension rod and a tool case.

This suits hobbyists and light home repairs where high torque is not needed. For stuck or rusty bolts, choose a higher-torque model.

Best for: Rusty bolts and longer work sessions

Pros

• 89 ft-lbs max torque
• Dual heat dissipation channels
• Light at 2.5 pounds bare

Cons

• Not made by DEWALT
• No speed figure listed

The 3 8-Inch Cordless Ratchet Wrench Compatible with DEWALT 20V MAX batteries is a Houselife tool, third-party and sold without battery or charger. It lists the highest torque here at 89 ft-lbs (the specs give 120 N·m, which matches), aimed at rusted bolts and stubborn nuts.

Dual heat dissipation channels help cool the motor during long use. It has a safety lock, forward and reverse button and automatic LED. It measures 15.3 by 2.3 by 2.1 inches and weighs 2.5 pounds bare. The kit includes 5 sockets (10 to 17mm), a 1/2 inch adapter and a 3-inch extension bar. Speed is not listed.

This fits people who deal with old vehicles and seized hardware. For a genuine DEWALT tool, the DCF510GE1 is the choice.
