DEWALT D25733K Review

When the job moves from drilling holes to breaking walls down entirely, the tool class changes. Standard SDS-Plus rotary hammers top out at around 28 mm and 3 to 4 joules — enough for anchors but nowhere near sufficient for demolishing a concrete staircase, breaking through a reinforced slab, or driving a 40 mm core bit through structural concrete. This is SDS Max territory. SDS Max tools use a larger shank, heavier internal hammer mechanisms, and deliver impact energy measured in double-digit joules. They trade finesse for raw breaking power. For contractors doing heavy civil work, foundation repair, large-scale anchoring, or any task where a smaller rotary hammer would simply stall, an SDS Max tool is not optional. Understanding the differences between SDS Max models — impact energy, weight class, vibration damping, and accessory compatibility — is essential because these tools represent a major investment expected to earn their keep on the toughest job sites.

SDS Max rotary hammers occupy the heavy end of handheld demolition and drilling. They use 18 mm shank bits — significantly larger than 10 mm SDS-Plus — and deliver impact energy typically from 8 to 20 joules. Where an SDS-Plus tool might take 30 seconds for a 25 mm hole through reinforced concrete, an SDS Max does it in 5. Critical specs include impact energy per blow, maximum concrete drilling capacity (this model handles 47 mm solid bits), weight (often 10-15 kg, making ergonomics and vibration damping paramount), and operating modes. Most professional SDS Max tools offer hammer drilling and hammer-only demolition; better models add rotation-only and vario-lock for directional chisel positioning. Active vibration control is non-negotiable at this weight class — without it, using the tool for more than a few minutes risks serious HAVS exposure.

This review examines the DEWALT D25733K, a corded SDS Max rotary hammer with 47 mm concrete drilling capacity and 3.7 Nm torque. We cover demolition and drilling performance, vibration control, handling at nearly 15 kg, included accessories, and comparison to equivalent Bosch and Hilti tools. With 4.9 out of 5 stars from 16 reviews, early adopters have been enthusiastic.

The DEWALT D25733K is a corded SDS Max rotary hammer built for heavy concrete drilling and demolition. It features an SDS Max chuck accepting bits up to 47.6 mm (1-7/8 inches) — large enough for serious through-holes in structural walls, core drilling, and heavy anchor installation. The motor delivers 3.7 Nm of torque and is powered by a 120V corded connection, suitable for North American job sites but requiring a step-down transformer for European use via this Amazon.fr listing. The tool measures 63.6 × 50.6 × 14 cm and weighs 14.5 kg (31.93 pounds) — a two-handed tool designed to be used from a stable stance with the tool's mass doing much of the work.

DEWALT has built the D25733K around their SHOCKS Active Vibration Control system, essential at this weight class. The system uses a spring-loaded counterbalance mechanism and vibration-isolating handles to reduce tremors transmitted to the operator's hands. Without effective vibration control, a 14 kg demolition hammer would be nearly unusable beyond minutes — with it, professionals can work in reasonable sessions. The rear D-grip handle provides secure two-handed control. The tool also features reverse rotation, useful for backing stuck bits out of deep holes without wrenching them free manually.

Operating modes include hammer drilling and hammer-only demolition — the two essentials for SDS Max. In drilling mode, the electro-pneumatic mechanism drives the bit forward while rotating, cutting through concrete. In demolition mode, rotation locks and the tool becomes a handheld breaker for slab demolition, wall removal, and concrete breakout. An angled chisel position lock (vario-lock) lets you set the flat chisel at the optimal angle for directional breaking — critical for controlled demolition where debris must fall a specific direction.

The D25733K ships as a kit with the tool, carry case, and basic accessories. DEWALT's standard warranty applies, and spares — brushes, seals, SDS Max chucks — are available through DEWALT's extensive service network. SDS Max tooling is a significant ongoing cost: quality bits, chisels, and core bits are expensive, and professionals typically accumulate several hundred euros of tooling. The good news is SDS Max is an industry standard — bits from any reputable manufacturer fit the DEWALT chuck.

At 14.5 kg the D25733K is at the heavier end of SDS Max — the mass helps power through concrete but makes horizontal and overhead work exhausting. Customer feedback is outstanding at 4.9 out of 5 stars from 16 reviews, though the sample is small. At €874.13, this competes directly with Bosch's GBH 11 DE and Hilti's TE 1000 series. For contractors regularly demolishing concrete, drilling large through-holes, or coring structural walls, the combination of DEWALT build quality, effective vibration control, and 47 mm capacity makes the D25733K a strong professional contender.

The DEWALT D25733K SDS Max rotary hammer is built for heavy civil contractors, foundation repair specialists, and demolition crews who need handheld concrete breaking and large-diameter drilling on demanding job sites.
