SundpeyPRO 21V Cordless Hammer Drill Review: a beefy DIY drill that feels more pro than its price

I’ve been using this SundpeyPRO 21V cordless hammer drill for a few weeks now on small DIY jobs at home and a couple of heavier tasks in the garage. I bought it mainly as a backup / house drill, not to replace my main corded SDS, so my expectations were pretty simple: enough power to drill in brick, batteries that don’t die after 10 minutes, and something that doesn’t feel like a toy. On paper, this thing is loaded: brushless motor, 120 Nm torque, 2 x 4.0Ah batteries, hammer mode, metal chuck, all the bits and sockets in a case.

In practice, it’s not a miracle tool, but it’s clearly not a cheap supermarket drill either. It feels closer to an entry-level pro drill than to a bargain bin kit. I’ve used it for drilling into brick walls for wall plugs, driving long wood screws into studs, and a bit of light metal drilling on steel brackets. I also lent it to a mate for a day, and he put it through some rough use on a fence job.

The main thing to know: it has plenty of power and the batteries last, but there are a few rough edges that remind you why it’s cheaper than the big brands. The case is flimsy, some of the included bits are just “OK”, and the finish is not at the level of a DeWalt or Makita. But for the price, and for home use, it honestly gets the job done without drama.

If you want a straight answer: if you’re a DIYer who drills into brick, wood and a bit of metal from time to time, this drill is more than enough. If you’re on site every day and your tools get abused non-stop, I’d still lean towards a big brand platform, but as a secondary or home drill, this SundpeyPRO is pretty solid.

For me, the value is where this SundpeyPRO kit actually stands out. You’re getting a brushless hammer drill, two 4.0Ah batteries, a fast charger, and a full set of basic accessories for the price of what a single bare-body tool can cost from the big brands. Of course, it’s not at the same level in every respect, but if you look at it from a practical point of view – what you can actually do with it – it covers 90% of what a typical DIYer needs at home.

Compared to my DeWalt drill, the SundpeyPRO is a bit rougher in finish, slightly noisier, and the trigger feels less refined. But in terms of actual work done – drilling in brick, driving screws, drilling in wood and light metal – it keeps up surprisingly well. For a professional who already has a battery ecosystem, it’s probably not worth switching, but as a first cordless drill or a dedicated “house drill” you leave at home, the price makes sense.

On the downside, the cost savings show up in the accessories and case. If you end up buying better bits and maybe a sturdier case or tool bag, the gap with a promo kit from a big brand gets a bit smaller. But even then, having two 4.0Ah batteries and a brushless motor at this price is still good value. You’re basically paying for the core tool and power setup, and treating the included bits as a bonus.

So, is it a good deal? For home users and casual DIYers, yes. You get enough power, decent runtime, and the flexibility of hammer mode without spending a fortune. For full-time trades, I’d say it’s more of a backup or loaner drill than a main workhorse, but even then, for the price, it’s not a bad addition to have lying around.

Visually, it’s a typical yellow/black drill, clearly inspired by the usual big brands. It’s not ugly, but it’s not trying to win any design awards either. What matters more is how it feels in the hand, and there it’s surprisingly decent. At about 4.1 lbs (with battery), it’s not super light, but the weight balance is good. The grip has enough rubber to feel secure, and the shape fits my medium-sized hands without feeling bulky. I’ve used it for about an hour straight doing wall plugs and didn’t end up with a sore wrist.

The 1/2" self-locking metal chuck is a good point. It feels more solid than the plastic chucks you often get on cheap drills. Bit changes are quick, and I didn’t have any slipping issues, even when drilling into brick on hammer mode. You can feel a bit of play if you really try to move the bit sideways, but nothing that affected accuracy for normal DIY work.

You also get a side handle, which is useful when you use hammer mode or drill larger holes in tougher material. The handle itself is basic plastic, but it locks well around the front collar and doesn’t twist under load if you tighten it properly. There’s also an LED light above the trigger. It’s not super bright, but it’s enough to see what you’re doing in a dim corner or under a shelf.

The selector rings (mode selector and torque settings) click into place clearly. The 2-speed slider on top is stiff enough not to change accidentally, but still easy to switch with one hand. Overall, the design is practical and straightforward. You can tell it’s not a premium tool when you look closely at the plastics and seams, but in the hand and in use, it feels more solid than the price suggests.

The 2 x 4.0Ah batteries are one of the big selling points, and in real use, they make a clear difference. With budget drills, the classic problem is: plenty of promises, but the battery dies after 20 minutes and you’re stuck waiting for a recharge. Here, with the brushless motor and the 4.0Ah capacity, I managed several small projects on a single battery without thinking about it. For example, one afternoon I drilled about 30 holes in brick (6 and 8 mm), drove a few dozen screws into timber, and the first battery still had juice left.

They claim about 2 hours of continuous operation on a full charge. Obviously, that depends on what you do, but in mixed use (some hammer drilling, some screwing), it feels realistic enough. I never drained a battery completely in one go; usually I’d get bored or finish the job before the battery gave up. Having the second battery ready is great: you can just swap and continue, which for a home user is more than enough.

The fast charger takes roughly 2–3 hours to fully charge a flat battery, which is okay, not lightning fast but acceptable at this price. The charger is basic: simple indicator light, no fancy display, but it does the job. It doesn’t get excessively hot, and I didn’t notice any weird smells or noises while charging. The batteries clip onto the drill firmly; no wobble or random disconnections while working.

Compared to my older 1.5Ah and 2.0Ah drills, this kit is clearly a step up in autonomy. You spend less time swapping or charging and more time actually working. For a full-time tradesperson who runs tools all day, you’d probably want more batteries and a more robust charging system, but for DIY and occasional heavier use, the battery setup is one of the best parts of this kit.

Durability is always the big question with these lesser-known brands. I haven’t had it for years, obviously, but after a few weeks of fairly rough use, I can at least say this: it doesn’t feel like it’s about to fall apart. The main body is solid, there are no weird creaks when you twist it, and the chuck still runs straight with no noticeable wobble. One Amazon reviewer mentioned dropping it a few times and it surviving fine, and I can believe that. I accidentally knocked mine off a workbench onto a concrete floor once, and apart from a small scuff on the plastic, nothing happened.

The metal chuck is reassuring. Cheap plastic chucks are often the first thing to go on low-end drills, but this one clamps well and still looks and feels the same after repeated bit changes and hammer drilling. The rubber on the handle and around the body is thick enough to provide some impact protection, though you can tell it’s not at the same level as a big brand pro drill in terms of finish and material quality.

Where it feels more “budget” is in the case and accessories. The case plastic is thin, and I wouldn’t trust it for everyday site work with tools being thrown in and out of vans. For home storage, it’s fine, but if you’re a tradesperson, you’ll probably end up putting the drill and batteries in your own toolbox or bag. The included bits are usable but I wouldn’t rely on them for long-term heavy use; I already swapped to my own masonry bits after a couple of jobs.

The overload and battery protection systems are a good sign for longevity. The drill cuts out rather than cooking itself, which should help the motor and batteries last longer. Obviously, I can’t tell you how it will behave after two or three years, but based on the feel, the internal protections, and the early signs, I’d say it’s reasonably durable for the price, especially for a home user or light site use. Just don’t expect it to survive daily abuse like a top-tier pro tool.

In terms of raw power, this thing is not shy. The spec says 120 Nm of torque, and while I can’t measure that precisely, it definitely has more punch than my older 18V brushed DIY drill. In low gear (0–600 RPM), I drove 6 x 100 mm wood screws into pine studs without pre-drilling, and it sank them fully without complaining. The torque clutch also works fine for smaller screws; once you dial in the right setting, you avoid stripping heads or burying them too deep.

In high gear (0–2150 RPM), it’s good for drilling in wood and metal. I used the supplied wood bits to drill 10–12 mm holes in some framing timber, and it went through easily. For metal, I tried 4–6 mm holes in steel brackets with some cutting oil, and it handled it at medium speed without stalling. The brushless motor feels smooth, and there’s less burning smell and noise than my old brushed drill when you push it.

On hammer mode, I drilled several 6 and 8 mm holes in brick for wall plugs. With the included masonry bits, it went through standard brick at a reasonable pace. It’s not as fast or comfortable as my corded SDS drill, especially in harder concrete, but for hanging shelves, curtain rails and fixing brackets, it’s more than enough. In harder, older concrete, you feel it working harder and the progress is slower, but it still gets there if you’re patient and don’t force it too much.

One thing I liked is the overload protection. I did manage to trigger it a couple of times when I really leaned on it in hammer mode. The drill just cut out, cooled down for a short time, and then came back fine. It’s a bit annoying when it happens in the middle of a job, but at least you know you’re not cooking the motor or batteries. Overall, for a home user and even for some light professional jobs, the performance is honestly solid, especially at this price level.

When you open the box, you get a full kit: the drill, two 4.0Ah batteries, a fast charger, a bunch of drill bits (wood, masonry, metal), some sockets, screwdriver bits, a flexible shaft, and a plastic carry case. On paper it looks generous, and honestly, for a basic home setup, you can start working right away without buying extras. That’s handy if you’re not already sitting on a pile of bits and accessories.

The drill itself is a 1/2" (13 mm) hammer drill with a brushless motor, two speeds, 20 clutch settings + 3 modes (screw, drill, hammer drill). It claims up to 120 Nm of torque and up to 2150 RPM in high gear. It runs on 21V lithium-ion batteries rated at 4.0Ah, and they say you get up to about 2 hours of continuous use per charge, which is roughly what I saw in mixed use (not pure nonstop drilling, but regular DIY work).

The accessories are a mixed bag. The wood bits are fine for basic holes, the masonry bits will handle standard wall plug holes in brick but I wouldn’t trust them for heavy concrete all day. The screwdriver bits and sockets are good enough for occasional use, but if you’re going to screw hundreds of screws, you’ll quickly want better quality bits. So I’d say: nice starter pack, but don’t expect premium accessories.

The case is where the cost-cutting is obvious. It does its job to store everything, but the plastic feels cheap and the latches don’t inspire confidence for daily professional transport. For home storage on a shelf, it’s OK. Overall, the kit is honest: you get a lot of pieces, the main tool is the good part, and the rest is serviceable but nothing special.
