In-Depth Reviews
1. Bosch GBH 18V-18 Cordless Rotary Hammer
The GBH 18V-18 sits at the sweet spot for UK makers who need a proper SDS drill without paying trade prices. At just 2.2kg, it's light enough to use overhead for fitting brackets or running cable clips into brickwork, but it still delivers 1.7 joules of impact energy, which is enough for 26mm holes in concrete with the right bit.
The brushless motor means longer runtime per charge and less maintenance. You get three modes: rotary only (for wood and metal), hammer drilling (for masonry), and chiselling (for light demolition like removing tiles). The chiselling mode is limited, but for occasional tile removal it saves you buying a separate tool.
This is a Bosch Professional tool, so it uses the 18V Professional battery platform. If you already own Bosch blue tools, the batteries are interchangeable. The body-only price means you'll need batteries and a charger if you're starting from scratch, but the compact design makes it an excellent primary SDS drill.
- Lightest in the roundup at 2.2kg
- Three-mode operation including chiselling
- Professional build quality at mid-range price
- Body only, no battery or charger included
- 1.7J limits it to smaller holes in hard concrete
- Chiselling mode is basic
2. Bosch UniversalHammer 18V Cordless Rotary Hammer
If you don't already own a Bosch battery platform, the UniversalHammer 18V is the easiest way into cordless SDS drilling. The kit includes a 2.5Ah battery, charger, and carrying case, so you're ready to go from the moment it arrives. At 2.0 joules, it delivers noticeably more punch than the GBH 18V-18, which matters when you're drilling into old UK brickwork that's harder than modern breeze blocks.
The UniversalHammer is part of Bosch's green (Home and Garden) line rather than the blue Professional range. That means a slightly less durable build, but for weekend projects, shelving, and general home DIY, the difference is negligible. The three-mode selection (drilling, hammer drilling, chiselling) covers the same ground as the professional models.
One practical advantage: the included L-BOXX-style case keeps everything organised. For makers who work in different rooms or take tools to a friend's house, having a proper case beats a cardboard box full of loose batteries.
- Complete kit with battery, charger, and case
- 2.0J handles harder brick and concrete
- Good value for first-time SDS buyers
- Green (home) line, not Professional blue
- 2.5Ah battery limits runtime on heavy jobs
- Slightly heavier than the GBH 18V-18
3. DeWalt DCH253N-XJ 18V XR SDS Plus Rotary Hammer
The DeWalt DCH253N-XJ is the tool you reach for when the job demands more than weekend DIY. With 2.1 joules of impact energy and DeWalt's XR brushless motor, it punches through dense concrete, engineering brick, and even lightweight blockwork with ease. The vibration control system reduces fatigue during longer sessions, which matters if you're drilling 20+ holes for a decking frame or running cables through an entire house.
Build quality is a step above the Bosch home-range options. The all-metal gear housing and tough chuck mechanism are designed for daily use on building sites. If you're a tradesperson or a serious maker who uses an SDS drill multiple times a month, the extra £50-80 over the Bosch options pays for itself in durability.
The LED work light with 20-second delay is genuinely useful in dark corners and underfloor work. Like the Bosch Professional, this is body only, but if you're already in the DeWalt 18V XR ecosystem, the batteries cross over with their combi drills, impact drivers, and circular saws.
- Excellent vibration control for extended use
- Heavy-duty metal gear housing
- Strong resale value in the DeWalt XR range
- Body only, premium price for tool alone
- Heavier than the compact Bosch options
- 26mm max in concrete, no SDS-Next
4. Bosch GBH 18V-26 F Cordless Rotary Hammer
At the top of the Bosch Professional SDS range, the GBH 18V-26 F delivers 2.6 joules of impact energy, the highest in this roundup. That extra power means faster drilling in hard concrete and the ability to handle 26mm holes without the motor struggling. If you regularly drill into old Victorian brickwork, reinforced concrete, or dense engineering blocks, this is the tool that won't leave you waiting for the battery to recover.
The "F" designation means it includes an auxiliary handle and depth stop, which are essential for accurate drilling at depth. The Vibration Control handle reduces transmitted vibration by roughly 50% compared to non-anti-vibration models, and the compact head length lets you work in tighter spaces than older rotary hammers.
The price is serious, and at body-only £284, you're looking at £350+ once you add a 5.0Ah battery and charger. But for professionals who use an SDS drill daily, the combination of power, ergonomics, and Bosch Professional build quality makes this a tool that'll last years. It's the kind of purchase you make once and forget about.
- 2.6J highest impact energy in this roundup
- Excellent vibration control system
- Includes aux handle and depth stop
- Most expensive option at ~£284 body only
- Total cost with batteries approaches £350+
- Overkill for light DIY tasks
5. Dong Cheng 20V Brushless Cordless SDS Rotary Hammer
Dong Cheng isn't a name most UK makers recognise, but this Chinese manufacturer has been making power tools for decades. The 20V Brushless SDS delivers 2.1 joules of impact energy and comes as a complete kit with a 4.0Ah battery, fast charger, four SDS bits, and a carry case, all for under £80. That's roughly a third of what the cheapest Bosch costs.
The brushless motor is a genuine surprise at this price point. Most budget SDS drills use brushed motors that wear out faster and drain batteries quicker. The Dong Cheng's brushless unit runs cooler and delivers consistent power through the battery's discharge curve. The four-mode selector (rotary, hammer, hammer-drill, chiselling) mirrors the functionality of drills costing three times as much.
Where it falls short is in long-term durability and parts availability. If something breaks after two years, finding a replacement chuck or switch isn't straightforward. But for occasional home use, drilling anchor holes in brick, or a first SDS purchase to see if you actually need one, the value proposition is hard to argue with. The included 4.0Ah battery also means longer runtime than the budget kits that ship with 1.5Ah cells.
- Complete kit under £80 with large 4.0Ah battery
- Brushless motor at budget price
- Four modes including chiselling
- Limited parts availability if something fails
- Build quality below Bosch/DeWalt standard
- No established UK warranty network
How to Choose a Cordless SDS Rotary Hammer Drill
An SDS rotary hammer drill is a different beast from a standard combi drill. The SDS (Slotted Drive System) chuck holds bits without tightening, and the hammer mechanism delivers impact energy through a pneumatic piston rather than a mechanical ratchet. This means faster drilling in concrete, brick, and stone with less effort from you.
For UK makers, the key decision is whether you need one at all. If you're drilling into brick occasionally, a standard combi drill with a hammer function might suffice. But if you're drilling more than a handful of holes in masonry each month, an SDS drill will save you time and wrist pain.
Impact energy (joules) determines how fast you drill through hard materials. 1.5-1.7J handles most DIY tasks. 2.0-2.2J is the sweet spot for regular masonry work. Above 2.5J is trade territory for dense concrete and engineering brick.
Battery platform matters more than the drill itself. If you already own Bosch 18V, DeWalt 18V XR, or Milwaukee M18 tools, buy the SDS from the same ecosystem. Batteries, chargers, and even tool bags are interchangeable, which saves money long-term.
Weight is critical for overhead work. Under 2.5kg is comfortable for fitting brackets above head height. Over 3kg is fine for bench work and floor-level drilling but tiring for extended overhead sessions.
Chiselling mode is useful but limited. It won't replace a dedicated SDS-Max demolition hammer, but for removing a few tiles or channelling a shallow cable run in plaster, it saves you buying another tool.

Final Verdict
For most UK makers, the Bosch GBH 18V-18 hits the sweet spot of price, weight, and capability. At around £110 body only, it delivers professional-grade build quality at a mid-range price, and the 2.2kg weight makes it comfortable for overhead work. If you're already in the Bosch 18V ecosystem, it's a no-brainer.
If you need a complete kit without already owning batteries, the Bosch UniversalHammer 18V bundles everything you need into one purchase. For budget-conscious buyers who want to try SDS drilling without committing serious money, the Dong Cheng 20V at under £80 delivers surprising value.
Serious makers and tradespeople should look at the DeWalt DCH253N-XJ for its vibration control and build quality, or the Bosch GBH 18V-26 F if you need maximum impact energy for dense concrete and engineering brick.
