Review and analysis

Impact wrenches are powerful cordless tools that provide high torque for loosening and tightening bolts and fasteners. They allow users to complete automotive repair jobs and construction projects much faster than using traditional hand tools.

Draper Tools has been manufacturing quality trade tools since 1919. Based in the UK, they offer a wide selection of power tools, hand tools, and workshop equipment. The Draper Storm Force 20V impact wrench is one of their flagship cordless power tools, designed for professional use.

This review will provide an overview of the key features and performance of the Draper Storm Force 20V impact wrench. It will cover power, speed, battery life, accessories, and ergonomics to provide a comprehensive look at this impact driver. Both the pros and cons will be examined to determine if this model is a worthwhile investment for automotive technicians and DIY mechanics.


The Draper 89519 Storm Force 20V 1/2" Square Drive Impact Wrench is a powerful and versatile cordless impact wrench. It features a brushless motor that delivers 155 ft-lbs of maximum torque and 0-2,600 RPM for driving and removing fasteners quickly.

This impact wrench has a compact and lightweight design, weighing only 2.4kg with the battery. It measures 237mm in length. The tool uses a 20V lithium-ion battery that provides longer runtime compared to older battery technologies. The 1/2" square drive with detent pin accepts standard impact sockets. An LED light illuminates the work area.

In addition to the cordless 89519 model, Draper also offers the 65017 Storm Force air impact wrench. This pneumatic tool delivers 295 ft-lbs of max torque with twin hammer mechanism. It has a 1/2" square drive and composite body to resist corrosion. The 65017 comes with a reaction bar to prevent user fatigue during prolonged use. It requires an air supply between 90-120 PSI.

Impact wrenches are designed for automotive repair, manufacturing, construction, and other applications requiring high torque. They use compressed air or battery power to generate rotational impacts that loosen tight bolts and nuts. The hammering action allows an impact wrench to deliver far more torque than a standard drill or driver.

Cordless models like the Draper 89519 offer the convenience of battery power without any air hoses getting in the way. They are ideal for mobile mechanics working on location. Pneumatic tools such as the Draper 65017 have the advantage of virtually unlimited runtime when connected to an air compressor. The choice depends on the intended application and workspace.

Features to look for in an impact wrench include brushless motors for efficiency, variable speed triggers for control, LED lights to illuminate dark areas, and protective bumpers. High torque ratings, durable housings, and reliability are also important. Brands known for quality include Ingersoll Rand, Milwaukee, Makita, DeWalt, and more.

Proper use and maintenance will keep an impact wrench performing optimally for years. Always use the correct size and grade of socket. Check air fittings for leaks if using a pneumatic tool. Allow the motor to reach full speed before applying load. Regularly blow out air vents and lubricate as directed. With cordless models, avoid completely draining lithium-ion batteries.


The Draper 89519 Storm Force impact wrench delivers excellent performance that meets the needs of most automotive and home DIY projects. It provides high torque output up to 300 Nm, which is more than enough for loosening even very stubborn bolts and lug nuts. The variable speed trigger allows you to dial in just the right amount of power, with no load speeds up to 2,100 RPM.

This impact wrench packs a serious punch thanks to its powerful 20V lithium ion battery. It can generate up to 1,400 impacts per minute, making quick work of jobs like removing wheel lug nuts or suspension components. The hammer mechanism is durable and designed for longevity.

Overall, the performance is highly impressive for a cordless impact wrench in this price range. It has plenty of fastening torque and speed to get the job done right. The variable speed trigger gives you great control over the power delivery. If you need an impact wrench that can handle automotive repairs and heavy-duty fastening tasks, the Storm Force delivers.

For even more power and performance, check out the Draper 99250 D20: 20V Brushless 1/2 Mid-Torque Impact Wrench (400Nm) - Bare. This model delivers an impressive 400 Nm of max torque while still being compact and lightweight. The brushless motor provides excellent power and runtime. With variable speed and an all metal transmission, it's built for durability under heavy use. If you need to blast off really stubborn bolts with ease, the 99250 D20 is a great choice.

With two great impact wrench options from Draper, you can tackle automotive repairs, construction jobs, and home projects efficiently. The Storm Force and 99250 D20 provide a blend of power, performance and versatility to get work done faster. Draper's lithium ion battery platform also ensures you get cordless convenience without sacrificing torque output or runtime. When shopping for an impact wrench, keep Draper models like these in mind.


The Draper Storm Force impact wrench is built to withstand heavy use in professional settings. The housing is constructed from durable composite materials that can handle drops and impacts without damage.

Draper has a reputation for making reliable power tools that stand up to prolonged use. The Storm Force lineup lives up to this reputation with an impact wrench designed for longevity.

The tool feels solidly constructed with quality internal components. The hammer mechanism and anvil are made to handle high torque applications without premature wear. The outer housing seems resilient to chips, cracks, and dents.

Overall, durability does not appear to be a concern with this model. It is made by a trusted brand and designed for professional use cases that require an impact wrench to hold up over time. The materials and build quality give confidence that this tool can withstand heavy workloads while continuing to perform.


The Draper Storm Force impact wrench is designed with ergonomics in mind to provide comfort during prolonged use.


The tool has an overmolded rubber grip that feels comfortable and secure in your hand. The grip has grooves for your fingers to nestle into, preventing hand fatigue. Even when wearing gloves, the grip remains easy to hold onto in slippery conditions.


At only 2.2kg, the Storm Force impact wrench is lightweight and well-balanced. The compact size allows you to wield it without straining your arms or wrists, even when working overhead or in tight spaces. The battery fits snugly at the base of the handle, keeping the center of gravity close for excellent control.


Draper has engineered the Storm Force impact wrench to minimize vibration. It uses a brushless motor that runs more smoothly than brushed motors. The rubber overmold grip also dampens vibrations from the impacts. These design choices help reduce hand numbness or tingling during prolonged use. The low vibration allows you to work comfortably for longer periods.

Battery Life

The Draper 89519 Storm Force impact wrench comes with a powerful 20V lithium ion battery that delivers excellent runtimes and fast charging. The battery is designed for maximum durability, with features like overload protection and heat resistance.

In terms of runtime, you can expect the battery to last through extended use. Many users report getting over an hour of continuous runtime even under heavy loads. This allows you to power through many tasks without needing to stop to recharge.

Charging the battery is also quick and convenient. It reaches a full charge in around 30-60 minutes when using the included rapid charger. This short charging time means you'll be back up and running in no time. The charger conveniently shows charging status via an LED indicator so you know when it's ready to go.

Overall, the battery life of the Draper 89519 is one of its major assets. The long runtimes and fast charging make it easy to work efficiently without any downtime. This capable battery delivers power and convenience.


The Draper 89519 Storm Force impact wrench comes with a few handy accessories right out of the box. It includes a belt clip for convenient portability when moving around a work site. The belt clip attaches securely to keep the tool handy without getting in the way.

It also comes standard with a battery charger that allows you to charge up the 20V lithium ion battery pack. The charger plugs into a standard wall outlet and has an LED indicator to let you know when charging is complete.

Some optional accessories are also available to further expand the capabilities of this impact wrench. An extended battery pack with higher capacity is available for longer run times between charges. Draper offers various screwdriver bits and sockets that can be used with the 1/2" square drive to increase the versatility of driving and removing different fasteners. An impact ready blow mold case provides protective storage and transport.

So while the Draper 89519 comes ready to use out of the box, there are some handy add-ons available for those who need extended runtime, additional driver bits, or rugged storage for their cordless impact wrench.


The Draper Storm Force Impact Wrench is priced competitively for an impact wrench of this quality and power. At around £80, it sits in the mid-range of prices for comparable 1/2" impact wrenches from other major brands like Makita, Milwaukee, or DeWalt.

Considering its durable all-metal gearing, powerful 20V motor, and 1/2" anvil for heavy-duty use, the Draper Storm Force represents very good value. It can handle professional jobs day after day without the price tag of some premium brands. For DIYers or home mechanics who only occasionally need this level of torque, the Draper is an affordable option that still delivers impressive power.

While more expensive than some budget impact wrenches, the Storm Force's performance and build quality makes the extra cost worthwhile for serious users. When you factor in the included 2Ah battery and charger, the overall package offers great value compared to other kits. Given its power and reliability, the Draper Storm Force impact wrench presents a nice balance of price and performance.
