Ryobi 18V One+ P237 Impact Driver Review

Ryobi P237 Angle 5

Quick take

The Ryobi 18V One+ P237 is intentionally built for homeowners that value versatility over performance. Ryobi made intelligent design decisions and sacrifices with the P237 to cater to that market while keeping the price incredibly low. The three drive modes vastly improve driving versatility, and it has exceptional battery life, two features rarely found in a cheap impact driver. The driving experience is also less violent than many models we’ve tested. While the driving speed and torque can be beaten, the P237 is powerful enough for any task around the home. The main downsides are an incredibly bulky footprint and heavy weight.

Max torque drive mode 3 (in-lbs): 159.6
Max torque drive mode 4 (in-lbs): N/A

The P237 doesn’t generate high torque output. But that’s not a downside for its intended audience of homeowners coveting versatility. The P237 is sufficiently powerful to handle any demanding task around the home.

All budget impact drivers make sacrifices. Ryobi made the right call to sacrifice torque in favor of including several drive modes. Homeowners are better off with driving versatility than brute force power.

Ryobi P237 RPM Charts

Max RPM drive mode 1 (fwd.): 3,079.0
Max RPM drive mode 2 (fwd.): 2,180.0
Max RPM drive mode 3 (fwd.): 1,469.0
Max RPM drive mode 4 (fwd.): N/A
Max RPM drive mode 1 (rev.): 2,464.0
Max RPM drive mode 2 (rev.): 2,134.0
Max RPM drive mode 3 (rev.): 1,496.0
Max RPM drive mode 4 (rev.): N/A

The P237 has average RPM output for an 18V impact driver. The RPM profile is balanced well for the intended user, who doesn’t demand best-in-class driving speed over all else.

The RPM profile also makes setting screws easier. Impact drivers that ramp quickly to a high RPM tend to spin out screws before settling into the workpiece. The P237’s RPM profile also helps to reduce cam-out and stripped threads.

One data point that is worth considering is the P237’s highest speed setting generates far higher RPM output in forward than in reverse. The lower RPM in reverse reduces the potential for cam-out when removing screws, albeit slowing down the removal process.

Driving speed

GRK total driving time forward (sec.): 18.4
GRK average driving time forward (sec.): 3.7
GRK total driving time reverse (sec.): 15.0
GRK average driving time reverse (sec.): 3.0

The P237 won’t win any driving speed contests, but that’s expected in this price category. However, it drove GRK structural screws reasonably fast in our heavy-duty driving speed tests, primarily due to its RPM output.

Throughout our testing, we were also impressed with the speed in light and medium-duty tasks, such as driving 3-inch and shorter screws into plywood and dimensional lumber.

Drive modes

Ryobi P237 Drive Modes

Drive modes: 3
Drive mode 1:  High speed 
Drive mode 2:  Medium speed 
Drive mode 3:  Low speed 
Drive mode 4:  N/A 
Variable speed trigger: Yes

The key standout feature for would-be P237 owners is that it’s one of the rare impact drivers at this price point to include several drive modes. Arguably, having access to several drive modes is more critical for homeowners wanting a versatile all-in-one tool than a higher torque or RPM output.

Drive mode 1 is the highest speed setting and is ideal for heavy-duty tasks, such as driving decking screws and lag bolts. This mode provides the highest torque and RPM output. Drive mode 1 didn’t consistently and accurately finish screws in our tests.

An accurate screw finish is where drive mode 2 is most helpful. We favored drive mode 2 over drive mode 3 for recessing screw heads since the lowest setting is underpowered for most tasks.

Drive mode 1 most accurately drove screws in low-density materials like drywall. But consider that drive mode 2 is faster and still accurate.


Ryobi P237 Collet Closeup

Collet size: 1/4-inch hex
Quick-change collet: Yes
Bit-eject collet: Yes
Easy-insert collet: Yes

One-handed bit changes are easy with the P237, thanks to the easy-insert and bit-eject mechanisms built into the collet. The bit-eject mechanism jettisons bits more powerfully than other impact drivers, sometimes resulting in not catching the bits. But after a few rounds of usage, catching the bit is easy and isn’t an issue.


Motor: Brushed
Impacts per minute: 3,200.0

Ryobi built the P237 with a brushed motor to hit such a low price point. While brushed motors can powerfully and quickly drive screws, they are less durable and less efficient than their brushless counterparts.

If your budget can support it, we recommend jumping up in price to a model with a brushless motor, such as the Ryobi 18V One+ PBLID02, if sticking with a Ryobi impact driver.

One reason why the P237 didn’t secure a podium position in any of our driving tests is its low 3200.0 advertised impacts per minute. Increasing the impacts per minute would help the P237 to achieve faster driving time in heavy-duty tasks, including our driving speed tests.

Battery run time

Power type: Cordless
Battery run time (min.): 48.0
Battery tested: 18V One+ High Performance 2Ah (PBP003)
Voltage: 18

The P237 has an exceptionally long battery life, as evidenced by its impressive performance in our no-load run-time tests. In subsequent rounds of testing, we will be running our test fleet through run-time tests under load. We’ll update this review with those results.

We tested battery run time with the 2Ah battery version. With an 18V One+ 4Ah battery, expect the battery run time to continue outperforming competing models running the same Ah setup.

Charging time 5Ah battery (min.): Not tested
Charging time per Ah (min.): 26.9
Fuel gauge: On battery

The 18V charger included with most Ryobi kits (model PCG002) charges batteries moderately slower than other brands.

Our tests took 49.0 and 117.0 minutes to charge a Ryobi 18V One+ 2Ah and 4Ah battery, respectively. Several other brands we’ve tested take approximately 20 minutes per Ah, whereas the Ryobi charger takes at least 24.5 minutes per Ah.

Don’t buy the P237 if you want a lightweight impact driver that won’t fatigue your arm and hand over long driving sessions. It is one of the heaviest models we’ve tested in its bare tool form and with a battery. We found throughout testing that our hands tired quickly, continually trying to hold the P237 upright due to the heavy, forward-balanced design.

Consider that the working weight can differ significantly depending on the battery run in your setup, which is why we tested the weight in different configurations. To keep it as lightweight as possible, we recommend combining the P237 with Ryobi’s 18V One+ 2Ah battery for a good balance of performance and weight.

If weight is less of a concern, pair the P237 with Ryobi’s 18V One+ 4Ah battery for a longer run time and improved driving performance.

Ryobi P237 Footprint1
Ryobi P237 Footprint2

Max height (bare tool, in.): 7.375
Max width (bare tool, in.): 3.250
Collet to back length (in.): 7.000
Base length (bare tool, in.): 5.125
Base width (bare tool, in.): 3.250
Trigger circumference (in.): 6.375
Handle circumference (in.): 5.250

Some of the weight is a result of the bulky footprint. The P237 is massive from tip to back compared to nearly all other impact drivers in our test fleet. Ryobi has standardized the base sizing for its impact drivers, and unfortunately, the bases are also comparably bulky.

The Makita 18V LXT XDT13Z is worth considering if you’re not wedded to the Ryobi ecosystem. The Makita model is far smaller and lighter.

Driving clearance

Min. interior width clearance (in.): 9.625
Min. top edge clearance (in.): 1.125
Min. interior 45-deg. clearance (in.): 7.250

The P237 is incredibly bulky. We don’t recommend this impact driver if you consistently drive fasteners in tight spaces. The collet-to-back length is among the longest we’ve seen.

A sub-compact or smaller footprint compact impact driver can squeeze into tighter spaces, especially if designed with a shorter collet-to-back length.

P237 Impact Driver Noise Chart

Max noise no load (dBA): 83.5
Max impacting noise (dBA): 96.1

The P237 is incredibly quiet when impacting compared to most impact drivers in our test fleet, including much pricier options.

The Milwaukee M12 Fuel Surge 2551-20 and Milwaukee M18 Fuel Surge 2760-20 are other options to consider for impressive noise output. Both are hydraulic impact drivers with far quieter impacts.

Compare noise test results


Max head vibration no load (m/s2): 75.1
Max grip vibration no load (m/s2): 2.1

We expected the P237 to be uncomfortable to use when impacting. However, it was one of our test fleet’s least violent and most comfortable impact drivers. The rubber overmold on the grip absorbs vibrations well, improving upon the already much smoother and less violent impacting mechanism.

Compare vibration test results


Ryobi P237 Light
Ryobi P237 Light Closeup

Light: Yes
Light on/off: No
Number of lights: 3
Light time delay (sec.): 10.0

We appreciate that the P237 has the work light built into the tip and points directly in front of the nose, unlike many other Ryobi impact drivers that build the work light into the base and shine the light upwards, sometimes not focusing the light in the right area.

There is no dedicated flashlight feature or the ability to disable the light, unlike some Makita impact drivers that include these features.


Tool warranty (years): 3
Battery warranty (years): 90 day

Ryobi offers an exceptionally-long three-year warranty on its impact drivers. However, Ryobi’s battery warranties don’t come close to matching the length provided by most other manufacturers. Ryobi has a 90-day battery warranty, whereas other manufacturers commonly offer two to three years of coverage.
