Power & Torque

The Sealey SV12 impact wrench delivers decent power and torque capabilities for a compact 12V cordless tool. It's equipped with a 3/8" square drive for versatility.

The brushless motor provides 270 Nm of max torque, which should be sufficient for most automotive and light industrial fastening applications. It can handle lug nuts, suspension components, and other stubborn bolts. The torque output is comparable to many 18V impact wrenches. For its size, the SV12 generates good RPMs up to 2,800. This gives it decent speed for driving and removing fasteners quickly. The variable speed trigger provides good control over the RPMs.

Overall, the power and torque is quite impressive for a 12V impact wrench. It packs a punch while still being lightweight and portable thanks to the compact battery design. The SV12 hits the sweet spot between power and convenience.

Sealey also offers the SV20 series of 20V impact wrenches for even more power. The SV20 1/2" Drive model delivers 340 Nm of max torque with up to 3,400 RPM. It's designed for more heavy duty applications where the 12V SV12 may not have quite enough grunt. With dual 20V batteries, the SV20 provides longer runtime as well. The brushless motor is efficient and maintenance free.

For mechanics, automotive technicians, and industrial users needing serious torque for lug nuts, axle nuts, suspension components, and other challenging fasteners, the SV20 20V impact wrench is a great option. It provides more power than the 12V SV12 but retains cordless convenience thanks to the latest lithium battery technology. The SV20 gives users the ability to tackle professional jobs without being tethered to a power cord.

In summary, Sealey offers both 12V and 20V cordless impact wrench models to suit different power needs. The compact SV12 is great for general automotive jobs where portability is key. When more torque is required, the SV20 packs a professional-grade punch in a convenient cordless package.

Battery & Charging

The Sealey CP1204KIT impact wrench comes with two 12V lithium ion batteries. The batteries have a decent run time, providing enough power to get through most automotive jobs before needing a recharge. While the batteries aren't best in class, they get the job done for most users.

The lithium ion batteries hold a charge well when not in use, so you don't have to worry about them self-discharging over time. The charger is quick and can fully recharge a battery in around 30-40 minutes. This allows you to get back to work without too much downtime waiting for the batteries to charge.

Some users may want to invest in an additional battery or two for marathon work sessions, but for most DIY mechanics the included set will be sufficient. The charger conveniently shows the charging status with an LED indicator, switching from red (charging) to green (fully charged).

Overall, the battery life and recharging performance is respectable for this class of impact wrench. The batteries are compact and lightweight, making the tool easy to maneuver. While more expensive brands offer better battery tech, the Sealey batteries deliver adequate run time for most users.

Noise Level

The Sealey SV12 impact wrench operates at a noise level of 88 dBa, which is typical for an air impact wrench of this size. The noise is noticeable but not excessive. Wearing ear protection is recommended for prolonged use, as per OSHA guidelines for noise exposure.

The noise comes mostly from the hammering action inside the tool. Some users may find it slightly louder than brushed motor impacts, but not uncomfortably so. It's quite comparable to similar impact drivers from other brands.

At a workplace, operating for an 8 hour shift, the noise level would require ear protection after just 15 minutes of accumulated exposure. In most home shops or garage use, the noise level is unlikely to be an issue except for extended, continuous operation.

Overall, the noise output is moderate and should not deter purchase for most users. Those highly sensitive to noise may prefer an electric or brushed motor impact instead. But for most, the SV12 hits a reasonable balance of power and noise.

Accessories

The Sealey CP1204KIT comes with a good selection of accessories for a cordless impact wrench kit. In the box you get:

• 2 x 12V 3.0Ah Li-Ion Batteries
• 110V Charger
• Storage Case
• 3/8" Drive Adaptor

Having 2 batteries is very convenient as you can have one charging while using the other, avoiding any downtime. The included charger plugs into a standard 110V socket and fully charges a battery in around 60 minutes.

The kit comes in a sturdy blow mold case that has custom cutouts for securely storing all the components. This makes it easy to keep everything together and protected.

It also includes a 3/8" drive adaptor which allows you to use standard socket accessories. This is a must have for versatility.

Overall the included accessories provide everything you need to start using the impact wrench right out of the box. The twin battery system prevents any charging delays during jobs. And the case keeps it protected for transport and storage.

Safety Features

The Sealey SV12 impact wrench has a few important safety features built into its design.

One key safety mechanism is the automatic brake. When the trigger is released, the brake engages to quickly stop the bit from spinning. This prevents potential injuries from the bit continuing to rotate after you stop using the tool.

There is also a safety slip clutch that helps prevent twisting your wrist or arms in the event of a bind-up. If the bit jams or gets stuck, the clutch will slip instead of your wrist taking all the torque. This reduces the chance of sprains or strains while using the wrench.

Additionally, the SV12 has an LED light that illuminates the work area for improved visibility. Being able to clearly see helps avoid accidents and potential hazards while operating the tool.

For operator protection, the housing is made from a durable composite material that won't conduct electricity. This insulates you from potential shocks in case you accidentally contact live wires while working in tight spaces.

Overall, the safety features like the brake, clutch, LED light, and insulated housing make the Sealey SV12 a safer choice for demanding impact wrench applications. These built-in mechanisms help reduce fatigue and injury risk compared to tools lacking such safety provisions.

Ease of Use

The Sealey SV12 impact wrench is designed with ease of use in mind. Its compact size makes it very maneuverable in tight spaces, allowing you to access hard-to-reach fasteners. The tool has an ergonomic rubber grip that provides comfort and control when using it.

The variable speed trigger gives you precision control over the torque output. You can start off slow to get a bolt loosened, then increase speed to zip it off quickly. The forward/reverse switch is conveniently located for quick direction changes. An LED light illuminates your work area for better visibility.

Weighing only 2.4 lbs with the battery installed, this lightweight wrench reduces user fatigue during prolonged use. The balanced design prevents your hand from getting tired. Overall, the Sealey SV12 is an easy to handle and operate impact wrench suitable for automotive and light industrial applications.

Price

The Sealey 12V SV12 Series 3/8" Impact Wrench Kit is very reasonably priced compared to similar models from other brands. At around £120-150, it offers great value given its power and performance.

Many competitors' cordless impact wrenches of comparable torque and features can cost upwards of £200 or more. So the Sealey represents a more budget-friendly option that still delivers professional quality and reliability.

When you consider you get two batteries and the charger included in the kit price, it's an even better deal. Additional batteries alone from some brands could cost £50-100 each.

Overall, the Sealey impact wrench gives you excellent bang for your buck. For DIYers or professional mechanics who don't want to spend a fortune but need a powerful and versatile tool, it's a very wallet-friendly choice worth considering.

The price-to-performance ratio offered by this Sealey model makes it stand out as one of the best value impact wrench buys currently available. You get pro-grade power and features without the premium price tag.
