Rank #5 in Best SDS Drill 2026: 10 Ranked, and Why the Amps Don't Add Up
DOVAMAN RH15A 1500W SDS-Plus Rotary Hammer, 7J
Price and rating as shown on Amazon when we collected them. Both change.
Fifth in this guide to SDS drills, the DOVAMAN RH15A is a corded SDS-Plus rotary hammer with a 1,500 W motor, four modes and 7 Joules of impact energy. It is listed at £119.97 and carries 4.4 out of 5 from 679 Amazon ratings. It arrives as a full kit — three SDS-Plus bits, a flat chisel, a point chisel, chuck adaptor and key, depth gauge, dust collector, spare carbon brushes, grease and a case — and it is heavy enough that the reviewers keep mentioning it.
Its place at number five comes from the same problem that runs through this guide: the numbers in the spec table do not agree with each other. Maximum power is stated as 1,500 Watts at 230 Volts, which would draw roughly 6.5 Amps; the same table instead lists 12.5 Milliamps, a figure that at 230 Volts works out at about 2.9 Watts. Maximum chuck size is filed as 40 mm, while the description in the same listing talks about a 1.5–13 mm quick-change chuck adaptor. Everything on this page is taken from the Amazon listing, not from our own testing.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I had to drill several 4" holes in my walls for ventilation. I went for max power with a clutch. It's a heavy beast, but 1500W of power behind it, what would you expect! It didn't break a sweat at any time. Good drill for someone who isn't drilling all day every day, in which case, I'd say spend the extra on a cordless.”
Verified purchase“I don't usually leave a review but with this drill, I just have to.It is absolutely brilliant! My daughter had a slopped concrete path she wanted removed. We tried lots of different tools and finally bit the bullet and brought this hammer drill.It's amazing and just eats through the stone filled cement. My dear grandson was the one doing it, as it's very heavy. I'm thrilled to bits and thoroughly recommend it to all who have a tough job ahead. I wish I'd brought it last week, before we started the job. Thank you.”

Questions people ask
How much power does the DOVAMAN RH15A have?
The listing states a maximum power of 1,500 Watts from a 230 Volt supply, with 7 Joules of impact energy and up to 4,350 BPM.
Why does the amperage figure look wrong?
The DOVAMAN RH15A spec table lists 12.5 Milliamps. At 230 Volts that is about 2.9 Watts, while the same listing claims 1,500 Watts — a 1,500 Watt tool at 230 Volts would draw around 6.5 Amps.
What can the RH15A drill?
DOVAMAN lists 40 mm capacity in wood and 13 mm in metal, and describes the drill as suitable for concrete, wood and steel. Four modes cover drilling, hammer drilling, chisel position adjustment and chiselling, switched on the same knob.
Is the DOVAMAN RH15A heavy?
The listing gives no weight figure, only a '8440.0 gram' unit count in the spec table, but reviewers describe it as a heavy beast. Vibration damping and a safety clutch are the listed comfort and protection features.
What comes in the box with the DOVAMAN RH15A?
A 1,500W rotary hammer, SDS-Plus adaptor and chuck key, three SDS-Plus drill bits, a flat chisel, a point chisel, two carbon brushes, a depth gauge, a wrench, a dust collector, a carrying case, grease and a user manual.
What do buyers think of it?
The listing carries 4.4 out of 5 from 679 ratings; in the published star breakdown 72 of 100 are five stars and 6 are one star.
