Intro

Whether you are assembling flat-pack furniture on a Saturday morning, putting up shelves in the living room, or tackling a bigger renovation project, one thing quickly becomes clear: a reliable drill driver is the backbone of every DIY toolkit. Driving screws by hand is slow, tiring, and often leads to stripped heads or wonky results. Drilling into wood, metal, or even masonry without the right tool can feel like a battle you are bound to lose. A good cordless drill driver takes the effort out of these jobs, giving you speed, control, and the freedom to work anywhere without dragging a cable behind you. But not all drill drivers are built the same — some struggle with tougher materials, others run out of juice halfway through the job, and many feel clumsy in the hand after just a few minutes of use. Finding one that balances power, battery life, and everyday ease of use makes all the difference between a project that flows and one that fights you every step of the way.

Generalities

Bosch has been a trusted name in power tools for decades, and their 18V cordless system is one of the most popular platforms for home DIYers across Europe. When shopping for a drill driver, the key things to look at are motor power, battery capacity, chuck size, and overall weight — these four factors determine whether the tool will breeze through your weekend projects or leave you frustrated. A 13 mm metal chuck, for example, means you can use a wide range of bits without needing adapters, while a 2-speed gearbox gives you the low-speed torque for driving screws and the high-speed rotation for clean, fast drilling. Battery compatibility also matters: if you already own other Bosch 18V tools, picking a bare unit or a kit that shares the same batteries can save you money and clutter. This Bosch EasyImpact 18V-40 sits in the brand's entry-to-mid range, designed to offer solid performance for everyday tasks without the premium price tag of the professional blue range.

In this review we will take a close look at what the Bosch EasyImpact 18V-40 brings to the table — its motor power and speed settings, how it handles on different materials, what comes in the box, and how it compares to other drill drivers in the same price bracket. We will also cover the real-world battery runtime you can expect, the quality of the included accessories, and whether this tool makes sense for your specific DIY needs. By the end, you should have a clear picture of whether this is the right cordless drill driver for your toolkit.

Description

At the heart of the Bosch EasyImpact 18V-40 is an 18-volt motor that delivers up to 40 Newton metres of torque and a maximum no-load speed of 1,630 RPM. The 2-speed gearbox gives you a low range of 0 to 430 RPM for controlled screw driving and a high range of 430 to 1,630 RPM for faster drilling. It handles wood up to 25 mm in diameter comfortably and can tackle metal, plastic, and even light masonry work thanks to the impact function. The kit comes with two 2.0 Ah lithium-ion batteries, which is a practical setup — you can keep one charging while you work with the other, so downtime is minimal. The LED charge indicator on each battery lets you see remaining power at a glance.

Design-wise, Bosch has kept things straightforward and user-friendly. The green body with black and red accents is compact and well-balanced, with a soft-grip handle that stays comfortable even during longer jobs. The 13 mm metal auto-lock chuck is a standout feature at this price — it tightens with a single hand, grips bits securely without slipping, and accepts a wide range of drill and screwdriver bits. A built-in LED light sits just above the trigger and illuminates the work area, which is genuinely useful when you are drilling inside a cupboard, under a sink, or in a dimly lit garage corner. The forward/reverse switch is easy to reach with your thumb, and the trigger feels responsive with good progressive speed control.

In everyday use, the EasyImpact 18V-40 feels light and agile. At 1.4 kg with the battery attached, you can work overhead or in tight spaces without your arm giving up after five minutes. The 2-speed gearbox shifts cleanly, and the 20+1 torque settings let you dial in just the right amount of force for the screw size and material you are working with — no more over-driving screws into soft wood or leaving them proud in harder surfaces. The impact mode adds a hammering action for masonry drilling, which is enough for small wall plugs and light brickwork, though it is not a substitute for a dedicated SDS hammer drill on heavy concrete jobs. The noise level is reasonable for a tool in this class, and the vibration is well-damped.

Everything you need comes in the sturdy transport case. Alongside the drill driver itself, you get two 2.0 Ah batteries, the AL 18V-20 charger, and a double-ended screwdriver bit to get you started right away. The charger is a standard Bosch unit that tops up a depleted 2.0 Ah battery in about 60 minutes, which is perfectly adequate for home use. The transport case is robust with a secure latch and moulded compartments that keep everything organised. Because the batteries are part of the Bosch 18V Power for All Alliance, they are compatible with dozens of other Bosch home and garden tools — hedge trimmers, grass shears, sanders, and more — so expanding your cordless collection is both easy and cost-effective.

The tool measures roughly 20 × 23 × 7 cm and is backed by a 2-year manufacturer warranty, with EU spare parts available for at least 1 year after purchase. Customer feedback is overwhelmingly positive: it holds a rating of 4.7 out of 5 stars from over 1,400 reviews, and it ranks at number 21 in the Drill Drivers category on Amazon France. It is also a top-5,000 bestseller in the broader DIY & Tools category, which speaks to its popularity among home users. For a cordless drill driver at this price point, that level of social proof is hard to argue with — real buyers consistently praise its ease of use, battery convenience, and solid build quality.

Pros and cons

Pros

  • Strong 40 Nm of torque handles most common DIY tasks — driving long screws into hardwood and drilling into metal are both well within its comfort zone.
  • 13 mm metal auto-lock chuck grips bits securely and makes bit changes fast with one hand — a feature usually found on more expensive models.
  • Two 2.0 Ah batteries included in the kit mean you never have to pause mid-job — swap and keep going while the other charges.
  • Part of the Bosch 18V Power for All Alliance, so the batteries work with over 40 other Bosch home and garden cordless tools.
  • Lightweight at just 1.4 kg with the battery attached — comfortable for overhead work and extended use without arm fatigue.
  • Built-in LED light and responsive variable-speed trigger give you precise control even in dark corners and tight spaces.
  • Impressive 4.7 out of 5 stars from 1,400+ real buyers — consistently rated highly for build quality, value, and ease of use.

Cons

  • The 2.0 Ah batteries are on the smaller side — heavy users tackling large projects may want to upgrade to 4.0 Ah or higher for longer runtime.
  • Impact mode is effective only for light masonry and small wall plugs — it cannot replace a proper SDS hammer drill for drilling into reinforced concrete.
  • Charger takes around 60 minutes to fully charge a 2.0 Ah battery — fast chargers found in Bosch's professional range are noticeably quicker.
  • Only one double-ended screwdriver bit is included — you will almost certainly need to buy a proper bit set for anything beyond basic assembly.
  • The plastic body, while light, does not feel as rugged as the glass-fibre reinforced housing found on Bosch's professional blue drill drivers.

Use cases

The Bosch EasyImpact 18V-40 is an ideal all-rounder for home DIYers who need one reliable cordless tool for assembling furniture, drilling into wood and metal, and tackling light masonry work around the house.

Flat-Pack Furniture Assembly

With 20+1 torque settings and precise variable-speed control, this drill driver makes light work of assembling wardrobes, bookcases, and desks. The clutch prevents over-tightening and stripping screw heads, so your IKEA projects come together cleanly without damaged fittings or sore wrists from manual screwdriving.

General Home DIY and Repairs

From putting up curtain rails and wall-mounted shelves to fixing loose door hinges and securing cable trunking, this tool covers the vast majority of household jobs. The compact size fits into tight corners, and the LED light helps you see what you are doing inside cupboards and under staircases.

Drilling into Wood and Soft Materials

The 1,630 RPM top speed combined with the 13 mm chuck makes quick work of drilling into softwood, hardwood, MDF, and plywood — up to 25 mm in diameter. Whether you are building a garden planter, fitting a cat flap, or running pipes through joists, the power is there when you need it.

Light Masonry and Wall Drilling

Switch into impact mode and the EasyImpact 18V-40 can handle bricks, aerated concrete blocks, and soft stone for installing wall plugs up to about 6 mm. It is not designed for heavy reinforced concrete, but for hanging pictures, mirrors, and lightweight cabinets on interior walls, it gets the job done without needing a separate hammer drill.

Expanding a Bosch 18V Cordless Collection

If you already own or plan to buy other Bosch 18V Power for All tools — such as a cordless sander, jigsaw, or garden trimmer — this kit is a smart purchase. You get two extra batteries and a charger that work across the entire range, effectively lowering the cost of every future bare-tool purchase.
