Best DeWalt Rotary Hammers – Overview of the 20V MAX Battery Line

TL;DR: The DeWalt DCH273B packs a brushless motor, SHOCKS vibration control and 2.1 J impact energy into a 5.95 lb, 20 V MAX cordless rotary hammer that earns a 4.7‑star rating from over 3,300 reviewers.

The standout feature is its brushless motor paired with DEWALT’s SHOCKS active vibration control, which together keep the 5.95 lb tool feeling steadier during prolonged drilling. At 8.6 in tall, 13.0 in long and 4.2 in wide, it balances a compact footprint with a 1‑inch (25 mm) SDS‑Plus chuck that handles most anchor‑hole jobs in concrete.

Compared with the four other rotary hammers in this roundup, the DCH273B sits in the middle of the size and weight spectrum. The DCH133B is lighter at 5.0 lb, while the FormiPow model is even lighter at 3.97 lb. The DCH293B feels significantly heavier, and the Securitoday unit does not list a weight. In terms of impact energy, the DCH273B’s 2.1 J trails the DCH133B’s 2.6 J, the DCH293B’s 3.5 J, the FormiPow’s 3 J and the Securitoday’s 2.5 J, making it the modest‑power option among the group.

Users consistently praise the brushless motor for durability and the included 360° side handle plus depth rod for better control in tight spaces. Professional reviewers note the high power‑to‑weight ratio, but they also point out that the tool lacks advanced safety features like E‑CLUTCH found in higher‑end models. Some owners mention that vibration is still noticeable during heavy chipping and that battery life can feel short when the hammer function is used continuously.

Best for: Buyers willing to invest in a proven, high‑quality option — the DeWalt DCH273B offers Impact Energy: 2.1 J

Avoid if: You're on a tight budget or only need basic functionality

TL;DR: The DeWalt DCH133B delivers 2.6 J of impact energy, a brushless 20 V motor, and a lightweight 5 lb build, earning a 4.8‑star rating from over 2,000 users.

This cordless rotary hammer packs a German‑engineered brushless motor that produces roughly 4,000‑5,000 blows per minute and 2.6 J of impact energy. The 0‑1,500 RPM no‑load speed and 1‑inch SDS‑Plus chuck let you drill and chip in three selectable modes, while the 5 lb weight keeps fatigue low during long jobs.

Compared with the other four tools in the roundup, the DCH133B sits in the middle of the weight spectrum—lighter than the premium DCH293B and the mid‑range DCH273B, but heavier than the ultra‑light FormiPow model. Its 2.6 J impact energy outperforms the DCH273B’s 2.1 J but falls short of the 3 J offered by FormiPow and the 3.5 J of the DCH293B. Lengthwise, the 16.0 in chassis is longer than the DCH273B’s 13.0 in but comparable to the FormiPow’s 15.0 in, giving it a solid balance between reach and maneuverability.

Professional reviewers note that the tool’s power is ideal for anchor installations and rod hanging, and users repeatedly praise its speed on concrete and the compact form factor that reaches tight spots. The most common complaint is noticeable vibration, which some users say leads to hand fatigue after many holes, and a tendency for the battery to drain quickly when the hammer mode is maxed out.

The DCH133B also includes a 360° side handle and a depth rod, and it comes with a three‑year limited warranty. Its three‑mode operation (drill, hammer drill, chip) and the lack of active vibration control are the main trade‑offs you’ll notice against higher‑end XR models.

Best for: Most users looking for a well‑reviewed, reliable mainstream option — the DeWalt DCH133B 1 inch offers Impact Energy: 2.6 Joules

Avoid if: You need advanced features or professional‑grade performance, such as active vibration control or higher impact energy for heavy chiseling.

TL;DR: The DeWalt DCH293B is a 20V MAX XR brushless rotary hammer delivering 3.5 J impact energy and up to 4,480 BPM, but its 8.71 lb weight and $447.22 price place it in the premium tier.

What really sets this tool apart is its 3.5 J impact energy paired with a brushless motor that pushes blows per minute from 0 to 4,480. The 20V MAX XR platform supplies cord‑free power while the SDS Plus keyless chuck accepts 1‑1/8 inch bits, and the anti‑rotation E‑CLUTCH plus SHOCKS active vibration control keep torque reaction and fatigue to a minimum.

Compared with the other four rotary hammers in this roundup, the DCH293B is noticeably heavier—at 8.71 lb it outweighs the FormiPow model (3.97 lb) and the DeWalt DCH273B (5.95 lb). It also out‑performs them on impact energy: 3.5 J versus 2.1 J on the DCH273B, 2.6 J on the DCH133B, and 3 J on the FormiPow. Those gains come at a premium price, making it pricier than the budget‑oriented Securitoday hammer.

Professional reviewers highlight the tool’s corded‑like power for large‑diameter holes and praise the ergonomic L‑shape handle with a 360° side grip. Users consistently note the reduced vibration during long sessions, but they also point out the heft and the $447.22 cost as hurdles for occasional DIYers.

Avoid if: You're shopping on a tight budget — it's priced at $447.22

TL;DR: At $58.99, the Securitoday Cordless SDS Hammer Drill packs a 2.5 Joule impact, 4‑in‑1 functionality and DeWalt‑compatible 20 V power, making it a solid budget choice for light concrete work.

The Securitoday Cordless SDS Hammer Drill delivers 2.5 Joules of impact energy at a rapid 6,200 BPM, and its brushless motor reaches a no‑load speed of 1,200 RPM. With a maximum concrete capacity of 1 inch, it’s built for light‑to‑medium masonry work. Four operating modes—drill, hammer drill, chisel, and chisel‑angle adjustment—let you switch tasks without swapping tools, while a built‑in LED keeps the work area illuminated. The L‑shape handle and 360° side handle add control in tight spots.

At $58.99, this unit sits well below the price of the DeWalt DCH293B, yet it offers a comparable 20 V MAX brushless platform. Compared with the FormiPow Rotary Hammer, the Securitoday model is taller—11.0 inches versus FormiPow’s 4.0‑inch height—so it occupies more space but still fits comfortably in a standard tool belt. Its 2.5 Joule impact sits beneath the DeWalt DCH293B’s 3.5 Joules, meaning it won’t match the raw power of premium rigs, but it outpaces many entry‑level hammers that list lower impact figures.

Reviewers consistently praise the tool’s portability and the convenience of tool‑free SDS‑Plus bit changes. The ability to run on existing DeWalt 20 V MAX batteries is highlighted as a cost‑saving perk for those already in that ecosystem. On the downside, users note that the battery and charger are sold separately, which can add to the overall outlay, and a few mention that the runtime feels short on demanding jobs. The 4.6‑star rating reflects generally positive feedback, though a few buyers wish for a more robust build for heavy demolition.

Beyond raw power, the drill incorporates an active vibration control system and an overload clutch, both aimed at reducing user fatigue and protecting the mechanism during tough encounters. The LED work light and anti‑slip grip improve usability in dim or cramped environments. Its 4‑in‑1 mode selection, combined with a sturdy metal depth gauge, gives you precise control over drilling depth, making it a versatile addition for contractors who need a lightweight, battery‑driven solution without sacrificing essential features.

TL;DR: The FormiPow Rotary Hammer Drill packs a 1250W brushless motor, 3 Joules of impact energy and a lightweight 3.97 lb body for fast, cordless concrete work at a budget‑friendly $89.99.

What really stands out is the 1250W brushless motor paired with 3 Joules of impact energy, which the manufacturer says yields up to 30% faster drilling in concrete. The tool’s compact 4.0‑inch height and 15.0‑inch length let you reach tight spots, while the 10.0‑inch width keeps it easy to grip. It runs on a 20V platform and accepts any DeWalt 20V Max battery, so you can swap batteries with other tools you already own.

Compared with the four other rotary hammers in this roundup, the FormiPow is lighter than the DeWalt DCH133B (5.0 lb), DCH273B (5.95 lb) and the heavyweight DCH293B (about 8.71 lb), yet it offers more impact energy than the Securitoday model (2.5 J) and the two lower‑end DeWalt units (2.6 J and 2.1 J). Its 4.0‑inch height is shorter than the Securitoday’s 11.0 inches and the DCH273B’s 8.6 inches, putting it on par with the DCH133B’s 3.9 inches.

Users consistently praise the drill’s light weight and the fact that it feels powerful enough for anchor‑drilling and small‑scale masonry jobs. Reviewers also note the convenience of the included three SDS‑Plus bits and a storage case. The main criticisms focus on the lack of a chipping mode and the fact that the 3 Joules impact energy, while respectable, falls short of the 3.5 Joules found in the premium DCH293B, limiting its usefulness on very hard concrete.
