Despite its compact size, the tool feels very solid and substantial in-hand thanks to its all-metal transmission and reinforced gearing. The slim grip profile offers excellent ergonomics for reduced user fatigue, allowing you to work comfortably even in tight spaces.

Attention has been paid to small details that enhance the user experience. Soft grip zones on the housing and side-handle promote a secure hold. A built-in LED light illuminates dark work areas. The battery fits snugly into the base without wobble. An anti-slip rubber pad on the base protects work surfaces from scratches.

Overall, the GDS 18V-1050 H reflects Bosch's reputation for precision German engineering. It's a robust and thoughtfully designed impact wrench built to provide years of reliable service under demanding professional use.

In addition to the GDS 18V-1050 H, Bosch offers other high-quality impact wrenches like the Bosch GDR 10,8-LI. This lightweight yet powerful cordless impact wrench delivers up to 108 ft-lbs of max torque while weighing only 2.9 lbs with battery. It utilizes Bosch's 18V Lithium-Ion battery technology for longer runtime and features a compact head design that can access tight spaces.

The GDR 10,8-LI has a durable all-metal transmission and hammer mechanism designed for heavy fastening applications. It provides 1,600 impacts per minute for efficient work progress. An integrated LED light illuminates dark areas. Soft zones on the housing enhance grip comfort during prolonged use.

Power & Performance

The Bosch GDS 18V-1050 H impact wrench features a powerful brushless motor that delivers impressive performance. It produces a maximum tightening torque of 1,050 Nm and a breakaway torque of 1,700 Nm, making it suitable for really stubborn and rusted bolts.

The motor provides efficient power while keeping noise to a minimum. It has two speed settings - 0-1900 rpm and 0-2800 rpm. This allows you to match the speed to the application, helping avoid overtightening damage. At 0-1900 rpm, it has more control for accuracy in delicate tasks. At 0-2800 rpm, it blasts through tough bolts quickly.

The wrench delivers up to 339 Nm of nutbusting torque, which gives it excellent power for breaking loose even corroded fasteners. The variable speed trigger gives you flexibility in adjusting the speed and power to the task. Overall, the GDS 18V-1050H combines high torque, fast speeds, and useful control features for demanding automotive and industrial bolting applications.

For those looking for a slightly less powerful but still high-performing cordless impact wrench from Bosch, check out the Bosch Professional GDS 18V-330 HC. This 18V cordless impact wrench provides 330 Nm of tightening torque and 560 Nm of breakaway torque. While less than the 1050H, it still offers ample power for most automotive and DIY applications.

The 18V-330 HC features a brushless motor for long life and efficiency. It has three speed and torque settings that allow you to match the power to the job. Speed 1 provides precise control at 0-1300 rpm for accurate tightening of small fasteners. Speed 2 generates 0-2200 rpm for most automotive jobs. Speed 3 delivers 0-3000 rpm for the highest torque and power. Like the 1050H, it has a variable speed trigger for even more control.

Weighing just 2 kg, the 18V-330 HC is lightweight and comfortable to handle. It measures only 155 mm in length for access in tight spaces. The 18V battery provides enough charge for about 200 bolts per charge. With the ability to switch between precision control and high power, this is an excellent mid-range impact wrench option from Bosch.

Both the GDS 18V-1050 H and the 18V-330 HC deliver the outstanding performance Bosch is known for. The 1050H is ideal for heavy duty bolting jobs where maximum torque is needed. The 330 HC gives users versatility in a compact size at a lower price point. Check out both models to see which Bosch professional cordless impact wrench is best for your needs.

Battery & Charger

The Bosch GDS 18V-1050 H impact wrench comes with Bosch's 18V Lithium-Ion batteries. The batteries have a large 4.0Ah capacity which provides excellent runtime.

One of the key benefits of the 18V system is that the batteries are compatible with Bosch's entire range of 18V tools. So if you already own other Bosch 18V tools, you can share batteries between them.

Charging is handled by Bosch's GAL 18V charger which can charge a single battery in around 60 minutes. This is quite quick for an 18V battery of this size. The charger plugs into a standard wall outlet.

In terms of battery life, you can expect around 80-100 bolts removed or tightened per full 4.0Ah battery charge. This will vary a bit depending on the size/tightness of the bolts. But for an impact wrench with over 1,000 Nm of torque, the battery life is very good.

Overall, the 18V battery system provides excellent power, quick charging, and good runtime for a high torque cordless impact wrench. The batteries are also compatible with Bosch's full line of 18V tools.

Noise Level

When it comes to noise level, the Bosch GDS 18V-1050 is relatively quiet for an impact wrench of this power class. Bosch rates it at only 81 dBa, which is comparable to a gas lawn mower. This is quieter than most competitors like the Milwaukee 2754-22CT at 85 dBa and the DeWalt DCF899P1 at 82 dBa.

Part of what keeps the noise down is the brushless motor design, which enables a more efficient power transfer. The motor itself runs very smoothly, without the high-pitched whine that some cheaper impact wrenches exhibit. The hammer mechanism is also well-dampened inside the housing to prevent excess vibration. Combined with the ergonomic grip, this makes the GDS 18V-1050 comfortable to hold during prolonged use.

The moderate 81 dBa noise rating means you can use the Bosch without ear protection for short periods. But for extended use, earplugs or earmuffs are recommended to prevent hearing damage from the cumulative effects. While not the absolute quietest, the GDS 18V-1050 strikes a good balance between power and noise for most users.


The Bosch GDS 18V-1050 H comes with a few handy accessories right in the box. Inside the sturdy L-Boxx storage case, you'll find the impact wrench itself, a 4.0Ah FatPack battery, an L-Boxx charger, and an auxiliary handle.

The included 4.0Ah FatPack battery provides longer runtime compared to standard batteries while still being compact and lightweight. It can deliver up to 390 watt-hours of power. The L-Boxx charger is designed to charge Bosch 18V batteries quickly and fits neatly into the case.

The auxiliary handle screws into the head of the impact wrench, giving you extra grip and control when dealing with stubborn bolts. This helps absorb vibration and makes the tool easier to hold steady.

While the impact wrench comes well-equipped, Bosch offers additional accessories you may want to add on. These include larger batteries for extended runtime, an L-Boxx wall mount for charging and storage, impact sockets in various sizes, and more. Purchasing some impact-rated sockets would be ideal to maximize the tool's capabilities.


The Bosch Professional GDS 18V-1050 H cordless impact wrench packs a serious punch in a lightweight, compact body. The brushless motor delivers an impressive 1050 Nm of max tightening torque and 1700 Nm breakaway torque, making it ideal for heavy-duty automotive and machinery work.

Despite its power, the tool weighs just 3.7 kg with battery, keeping fatigue at bay even after extended use. The slim handle design enhances grip and control as well. Bosch's 18V Lithium-Ion batteries provide long runtimes per charge and have no memory effect or self-discharge.

An integrated LED light illuminates dark work areas. The impact wrench has robust metal gearing and housing to withstand job site abuse. Variable speed control allows you to match power to the application. An all-metal quick release chuck makes bit changes fast and easy. Overall, a lightweight yet hard-hitting cordless impact wrench suited to pros.


The Bosch GDS 18V-1050 does have some drawbacks to consider.

Price - This is a professional grade tool aimed at serious DIYers and tradespeople, so it comes with a professional grade price tag. At around £650, this is a significant investment that may be out of reach for casual users or those on a tight budget. While the performance and power warrant the price, it's still a lot of money compared to more basic DIY impact wrenches.

Noise - With its brute power comes noise. This is one of the loudest impact wrenches on the market, producing up to 93 dB of noise in operation. That's very loud, on par with a motorcycle or lawnmower. Extended use without hearing protection is not recommended. Those sensitive to noise may find it uncomfortable to use, especially for longer jobs. Ear defenders are a must.

Weight - At 2.6 kg including the battery, this is a relatively heavy and bulky tool. The weight could become tiring if using it overhead or for long periods. The compact head does help offset the weight somewhat, but it's still hefty for an 18V cordless tool. Those who prioritize light weight and compact size may find it too bulky.

Battery Life - While decent, the battery life is not exceptional. With heavy use, expect no more than 20-30 minutes of runtime. Plan on having 1-2 spare batteries for longer jobs or all day use.

Overall the powerful performance comes with tradeoffs of high price, noise, and bulk. For professional use the pros easily outweigh the cons, but it may be overkill for light DIY use.
