Great bit of kit

- Reviewed in the United Kingdom on 28 August 2025Pattern Name: SingleVerified PurchaseI recently purchased the Silverline DIY 850W SDS Plus Hammer Drill, and it has quickly become my go to tool for home and DIY projects. The drill is extremely powerful and can handle both wood and masonry effortlessly. There’s no wall it can’t drill through.
It’s very well-built and durable, with an ergonomic design that makes it comfortable for short to medium use. The only downside is that it’s quite heavy, so prolonged use might be challenging for someone with less strength, like my wife.
The SDS Plus system allows quick bit changes, and the variable speed control provides precise handling depending on the material. Overall, this is a high-quality, reliable hammer drill that’s perfect for DIY enthusiasts looking for power and durability. I would definitely recommend it.
- Reviewed in the United Kingdom on 15 June 2023Pattern Name: SingleVerified PurchaseBeing an old school 13mm chuck guy, I have shied away from an sds. But needing to screw 18mm osb board to red brick garage floor and needing 150 concrete screws fixing, I thought I would give one a go. And what a piece of kit this is. Using drill and chisel action, it drives the drill bit effortlessly through the bricks that are hard as bullets. Makes drilling hard materials easy as butter. The kit was complete enough for me to do job without purchasing extras as needed 6mm masonry bit for concrete screws. Grease the drill bit first on shank end for easy removal from chuck after use.
The chisel action for breaking bricks is awesome. Smashed them to bits.
Heavy item but only a sign of quality materials used. Make sure you fill the grease for chisel workings first b4 use.
Only problem I had is plastic screw cap for grease on drill had been overtightened on assembly so was very tight to unscrew which resulted in bending the unscrewing tool. But it is the same tool needed to change discs on a 4 1/2 inch angle grinder in which I have plenty so no issues.
The price and next day delivery, one can’t grumble at all. Very happy with purchase.
Sds bits don’t slip like 13mm chuck as locked in with groves. Even went on to fit load of shelves in garage for more space and tidiness.
Brilliant for any Job at home regarding breaking concrete etc or drill through wood and into brick etc. I would say this drill would be suitable for medium use on larger products or at least a good back up tool. Brushed motor but does come with spare brushes so should last a long time. Value for money.
- Reviewed in the United Kingdom on 19 August 2023Pattern Name: SingleVerified PurchaseWell my trusty 20+ yr old cheapo JCB sds drill finally gave up the ghost while drilling 13mm holes in some oak sleepers, I only had 2 holes to go so in desperation as it was Friday afternoon and I needed a replacement next day I ordered this Silverline sds drill as it was one of only a few that were available next day, ive got other silverline tools which are OK so thought I would be safe.
Item arrived Saturday afternoon and on first impressions it looked an OK piece of kit for the money, a quick read of the instructions and it said to check the gearbox grease level before first use,
so gearbox cover spanner in hand I attempted to remove the cover, wow that didn't want to budge, I applied a bit more pressure and bang the spanner slipped and my hand slammed into the selector switch adjacent, a week on since then I've still got bruising and swelling in my little finger, not impressed. I finally got the cover off with putting all my strength into pushing it down with one hand and turning with the other, problem found the manufacturers had totally cross threaded the cover on putting it on, now there was loads of shards of the plastic thread inside the gearbox, OK I will be sending it back on that basis anyway but let's get those last 2 holes drilled
off outside I went, got my tools out, unravelled the extension lead to the top of the garden, fitted the chuck and 13mm drill bit, switch on, drill turns till around 10mm into the sleeper and drill bit stops turning and smoke pours out of the motor housing, what utter junk!!!
Returned for refund which I had to waste more time on taking to a parcel drop-off shop.
- Reviewed in the United Kingdom on 12 October 2024Pattern Name: SingleVerified PurchaseAmazon rubbish, Silverline fantastic. I received this through Amazon the package was beaten to the point where it was falling apart and it also looked like it had been thrown in the sea. The cardboard was so wet only the tape was keeping it together. Needless to say the water had also gotten into the plastic wrapped carry case inside and started to rust the individual bits. Amazon delivery should be ashamed. Couldn’t get hold of Amazon and eventually found a link to Silverline. They were fantastic even though they were not at fault for the damage they stood behind their product and sent me a new drill (I was afraid to use the original because of the water damage and rust).
Now to the drill. You get a lot for your money. The tool for opening the gearbox cover is made of cheap soft metal and bends very easily so I made another out of better grade steel using the original as a pattern. That is the only negative I can find with this. If using it as per the instructions and not expecting it to be in the same league as a Rock Drill or Jack Hammer it does very well. Have been using it on a concrete footing, be patient and let the tool do the work and take off a bit at a time and this works great.
Reading the reviews it appears to me that many users do not understand that, it is not a miracle tool it is just a well made heavy hammer drill that does the job it is designed for.
- Reviewed in the United Kingdom on 26 March 2025Pattern Name: SingleVerified PurchaseSilverline DIY 850W SDS Plus Hamme drill is great value for money a well built bit of kit comes with drill bit accessories and a strong plastic carrying case
The reason I bought was I was in the market for a drill that I could really rely on if my other SDS branded drill ran out of power while on a job
I’m very pleased with my purchase and would highly recommend the Dealer/Seller and purchasing through Amazon gives you the added value and security knowing that your purchase is going to arrive
I’m not an influencer nor am I being paid for my review I’m probably like you a keen DIY enthusiast looking for a good deal and that scores 5/5 for me

Pattern Name: SingleVerified Purchaseil demolitore è piccolo ma fa bene il suo lavoro. il percussore del trapano è particolarmente violento e richiede molta forza per mantenerlo fermo. non è semplice forare superfici dure.
derek sharplesReviewed in Spain on 20 September 20154.0 out of 5 stars Silverline 850 SDS Plus Hammer Drill.
Pattern Name: SingleVerified PurchaseI already have a Silverline 230 angle grinder which I am really pleased with. So when my Parkside (Lidl) hammer drill packed in due to poor quality/bad design, I had no hesitation in sourcing a Silverline one. After using it today, I am really pleased with it, though I have to agree with other peoples comments regarding the on/off switch; very awkward to keep the machine switched on if you change its position when using it.
If I need other power tools or other equipment in the future, then I will check to see if Silverline,com can supply them.

CédReviewed in France on 24 March 20185.0 out of 5 stars Agréablement surpris !
Pattern Name: SingleVerified PurchaseQu’elle bonne surprise, utilisation pour casser un énorme bassin béton armé dans mon terrain, où une mini-pelle ne pouvait passer, j’en ai passé du temps dessus mais ce perfo à fait son travail sans faillir, je ne peux que le recommander, à la limite, son seul point faible est sa caisse de transport fragile qui est déjà à la poubelle mais le perfo en lui-même, c’est du béton !!!
