Stanley FATMAX V20 18V Review: a no-nonsense cordless drill that hits hard for DIY use

I’ve been using the Stanley FATMAX V20 18V impact drill for a few weeks now for typical home jobs: mounting shelves, drilling into concrete walls, assembling furniture, and some light renovation work. I’m not a pro, but I do enough DIY to notice when a drill is weak or badly designed. This one sits somewhere between the cheap weekend-warrior tools and the pro gear like DeWalt or Makita.

The first thing that struck me is that it feels like a real tool in the hand. It’s not ultra compact or super light, but it doesn’t feel flimsy either. With the 2 Ah battery in, it has a bit of weight, which helps keep the drill stable when you’re drilling into masonry or using the hammer mode. If you’re used to small entry-level drills, this one will feel more serious right away.

I mainly used it on brick and hollow block walls, some concrete lintels, plus a bunch of wood and metal jobs. It handled most of that without complaining. It’s not a rotary hammer, so you shouldn’t expect miracles in very hard reinforced concrete, but for home use it gets the job done. I did hit its limits once or twice in very hard spots, but overall it performed well for its category.

In short, my first impression is: solid, efficient enough, and pretty practical with the two batteries and the case. Not perfect, not the strongest on the market, but clearly a good step up from the basic cordless drills you see in supermarkets. The rest of this review goes into the details: design, performance, battery, durability, and whether it’s good value for the money.

In terms of value, this Stanley FATMAX V20 kit sits in a middle zone. It’s clearly more serious and better built than the bargain cordless drills you see in supermarkets or discount stores, but it’s also cheaper than the big pro brands when you compare similar brushless kits with two batteries and a case. For someone who does regular DIY and small renovation work, I think the price-performance ratio is pretty solid.

You’re paying for a few key things: the brushless motor, the hammer function, the two batteries, and the compatibility with the V20 platform. If you only need a drill for assembling IKEA furniture twice a year, this is probably overkill, and you could save money with a simpler model. But if you regularly drill into masonry, mount furniture, work with wood and metal, and want a drill that doesn’t feel weak after six months, the extra cost makes sense.

The Amazon rating around 4.3/5 also reflects this. Most users are happy with the power, robustness and battery life for the price. The main negative feedback I saw was related to the condition of the product on delivery (case, labels, possible returns), which is more about the seller than the tool itself. Technically, for the money, you get a decent level of performance and a complete kit that lets you work right away without needing to buy extra batteries.

If you compare it with higher-end pro models, yes, they often have more torque, better hammer performance in concrete, and sometimes better cases or extra features. But they also cost noticeably more, especially once you add a second battery. So I’d say this Stanley kit is good value for a demanding home user or an occasional pro. There’s better on the market if you’re willing to pay more, and there’s cheaper if you accept lower performance, but this one is a nice balance between price, power and durability.

From a design point of view, the Stanley FATMAX V20 is pretty classic: black and yellow, thick handle, and a fairly chunky body. It’s not the most compact drill I’ve had in my hands, so if you’re working in very tight spaces every day, it might feel a bit bulky. But for home jobs and small renovation work, the size is perfectly fine. The extra volume comes from the brushless motor and the reinforced housing, which is glass-fibre reinforced according to the specs, so it’s clearly made to take a few knocks.

The grip is comfortable. The rubber coating on the handle is grippy without being sticky, and after several sessions of drilling above my head, I didn’t feel like it was slipping or twisting in my hand. The balance with the 2 Ah battery is decent: the drill doesn’t tip forward too much, and you can hold it straight quite easily for precise drilling in wood or metal. I’d say it’s well balanced for a mid-range tool. It’s not featherlight, but it feels stable, which is more important when you hit harder materials.

I also liked the small practical details: there’s an LED light at the base that turns on with the trigger, which is handy in dim corners or inside furniture. It’s not a floodlight, but it’s enough to see where you’re drilling. There’s also a battery charge indicator directly on the battery, so you can check the level before climbing a ladder or starting a job. It sounds minor, but it avoids some annoying surprises, like a dead battery just when you’re halfway through mounting a shelf.

On the downside, the case is a bit basic. It does its job, but the plastic doesn’t feel premium, and the closures don’t inspire huge confidence if you’re going to throw it around in a van every day. For a home user who stores it in a garage or a cupboard, it’s fine. For a full-time tradesperson, I’d be a bit more careful. Also, the drill doesn’t have a side handle, which would have been useful when using it at full torque in tougher materials. It’s manageable without it, but sometimes you feel the wrist working hard when a bit grabs suddenly.

The kit comes with two 2 Ah batteries, and that’s one of the main strengths of this package. 2 Ah is not huge, but having two packs changes everything in practice. During my tests, I could work for quite a while on a single battery when doing mixed tasks: drilling some holes, then driving screws, then a bit more drilling. For pure drilling with hammer mode in masonry, you see the charge drop faster, but that’s normal for any cordless drill.

On average, with a full charge, I could do a full small project: for example, mounting several shelves (about 20 holes in masonry, plus a bunch of screwdriving) without having to swap the battery. On a more intense session, like drilling a series of holes in brick walls for anchors, I ended up swapping after maybe 40–50 medium jobs. It depends on your bits and how hard the material is, but you get the idea: it’s not a marathon runner, but it’s not dying after 10 minutes either.

The charger is fairly standard. It’s not ultra fast, but it recharges a 2 Ah battery in a reasonable time. In my case, by the time I’d used the second battery, the first one was often nearly full again, which means that with a bit of organisation, you can work almost continuously on DIY projects without being blocked. For professional use where you’re constantly drilling or driving, I’d probably invest in higher-capacity batteries (4 Ah or more) if the budget allows, because 2 Ah packs do empty faster under heavy load.

The battery indicator is a small but very useful feature. You can check the remaining charge before starting a job, which avoids climbing a ladder or moving furniture only to find the drill dead. The V20 platform is also a plus: if you already have other Stanley V20 tools, you can share the batteries, which makes the whole system more interesting. In short, the battery setup in this kit is practical and well thought out for home users and occasional pros, but heavy users might outgrow the 2 Ah capacity fairly quickly.

On the durability side, I obviously can’t judge after years of use, but I can share what I’ve seen so far and how it compares with other tools I own. The drill housing feels solid. The shell is reinforced with glass fibre according to the specs, and you can feel that it’s not thin plastic. I’ve already knocked it against walls and dropped it from about waist height onto a wooden floor once (my fault), and it didn’t show any damage apart from a small scuff on the plastic. No cracks, no weird noises, nothing loose.

The brushless motor is another good point for longevity. In my experience, brushless drills tend to hold up better over time and keep their power longer, especially if you don’t abuse them constantly at full load. They also heat up less. After several long drilling sessions, the drill body was warm but not worryingly hot. I never had to stop because of overheating, which sometimes happens with cheaper brushed models. That’s a sign that the internal design and ventilation are decent.

Where I’m a bit less convinced is the carrying case. It does the job, but the plastic hinges and latches don’t feel very strong. For someone who keeps their tools mainly in a garage and moves them occasionally, it’s fine. For a tradesperson who throws the case in and out of a van every day, I can see those latches wearing out or breaking sooner. Also, one Amazon review mentioned receiving a unit with labels removed and a case not closing properly, which raises some questions about quality control at the seller or warehouse level. My own case is okay, but it’s something to be aware of.

Overall, the drill itself gives off a solid impression, better than many entry-level brands. The combination of the brushless motor, reinforced shell and general finish suggests it should last if used reasonably. If you’re the kind of person who takes basic care of their tools (don’t leave it outside in the rain, don’t drop it from a roof), I don’t see any obvious weak point on the tool itself after my tests.

In terms of performance, I put this drill through the usual tasks: drilling 6–10 mm holes in brick and concrete for wall plugs, drilling 20–25 mm holes in wood for furniture assembly and small framing, and some metal drilling up to 8 mm. It handled all of that without any real drama. The torque is clearly there for screwdriving: even long screws in wood go in smoothly if you pick the right speed and clutch setting. Compared to a cheap brushed 18 V drill I used before, the difference is clear: this one doesn’t bog down as quickly.

The hammer function is decent. In regular masonry (brick, hollow blocks), it works well. Holes for plugs up to 8 mm go in at a reasonable pace with standard masonry bits. Where it shows its limits is in very hard reinforced concrete. I tried drilling into a reinforced lintel above a window, and it managed, but it took time and I had to lean on it quite a bit. A user review mentioned that the percussion is a bit weak in reinforced concrete, and I agree. For that kind of job, a proper SDS rotary hammer is still the better choice. But for typical DIY tasks, hanging kitchen units or shelves on normal walls, it gets the job done.

The two-speed gearbox is useful. Speed 1 has a lot of torque and is good for screwdriving and larger bits in wood. Speed 2 spins faster and is better for small drill bits in metal or for quick drilling in softer materials. The clutch has multiple positions and works correctly: I didn’t strip any screws, and it stopped where I expected most of the time. The chuck grips well and I didn’t have bits slipping, even in hammer mode. There’s a tiny bit of play at the tip, but nothing that bothered me in real use.

Overall, performance-wise, I’d call it a solid mid-range cordless hammer drill. It’s strong enough for serious DIY and light professional tasks, but it’s not a monster like some high-end pro models with bigger batteries. If your main job is drilling endless holes in hard concrete all day, this is not the right tool. If you mainly do mixed tasks (wood, metal, masonry, screwdriving) around the house or on small sites, it’s more than enough and feels reliable.

Let’s start with the basics: what’s in the package. You get the Stanley FATMAX V20 18V brushless hammer drill, two 2 Ah lithium-ion batteries, a charger and a plastic carrying case. No bits, no drill set, no fancy extras. It’s just the tool and what you need to run it. Personally, I prefer that over fake bundles with ten low-quality bits that I’d throw away anyway.

The drill itself has a brushless motor, which is a good point for efficiency and lifespan. The specs say up to 80 Nm of torque, two speeds (up to about 1900–2100 rpm depending on which line you read), and an impact rate up to 32,300 blows per minute in hammer mode. There’s a 13 mm keyless chuck, so you can use normal bits for wood, metal and masonry. The listed drilling capacity is 13 mm in wood and 13 mm in metal, which is a bit conservative in wood in my opinion, but at least they’re not overselling it.

The kit weighs around 3.3 kg with everything, and the drill with a battery feels reasonably balanced. The case is a classic blow-moulded plastic box. It’s not luxury, but it protects the tool and keeps the charger and batteries together. Some people complained online about receiving a unit that looked like a return, with labels removed and the case not closing properly. Mine arrived new and clean, with stickers and internal layout intact, so that sounds more like a seller issue than a product design problem, but it’s worth keeping in mind if you order online.

Overall, presentation-wise, it’s pretty straightforward: a mid-range drill-driver with hammer function, brushless motor, two small batteries and a case. No nonsense, no bells and whistles. If you already have V20 tools, the batteries are compatible, which is a real plus. If not, this kit is a decent starter pack for someone who wants a cordless drill that can handle both drilling and screwdriving without swapping tools all the time.
