The Best Rotary Hammer Drills: How To Find The Right For The Job

The Best Rotary Hammer Drills: How To Find The Right For The Job

Rotary hammer drills are power-packed tools with the ability to drill through nearly any type of barrier and chisel out even the toughest materials. Purchasing a rotary hammer can be daunting, especially when most tools have professional-grade ratings and equipment.

Whether you are an around-the-house DIYer or a professional shop owner, we have the rotary hammer drill for your needs. Here we’ll look at the different types of rotary hammer drills and the features to look for, plus give our recommendations for the seven best options on the market.

Bottom Line Up Front

Our top pick for the best rotary hammer drill is the Bosch SDS Rotary Hammer RH328VC, which combines a mid-range drilling diameter max (1 1/8 inches) in a compact package. Its weight is on the heavier side, but for the features it packs, it’s a tradeoff we can live with.

Bosch’s RH328VC accepts SDS bits, and the availability of adapters may mean you can use existing hardware with your new rotary hammer. Ample vibration control and comfortable ergonomics are also highlights, making the RH328VC our top choice. If this isn’t the tool for you, read on for more about different types of drills and our top seven recommendations.

Different Types of Rotary Hammer Drills

Rotary hammer drills, which are often known as rotary hammers, combine hammering and drilling forces to power through masonry and other tough surfaces. Most drills use the same functions, but you’ll find a handful of varying features on these drills.

Drill Modes

Many rotary hammer drills on the market today offer multiple operation modes. Our picks below have various modes such as chiseling, hammer drilling, and rotation only, making them a more versatile tool.

The reverse is another desirable and helpful feature for starting projects and one you’ll find on most of our recommended drills. Especially for hammering modes, kickback prevention helps make drilling more comfortable, another way the multiple modes feature helps make using the tool easier overall.

Corded vs. Cordless

Because of the amount of power they offer, you might expect a rotary hammer drill to always rely on corded power. Battery power is becoming more common in every type of power tool, though, so we’ve included two cordless rotary hammer drills on our best-of list.
Portable power tools aren’t for everyone, but there are certain situations where they’re invaluable.

To ensure we cover every need, we made sure to look at the more reliable battery-powered rotary hammer drills on the market, which include both an 18V and a 20V option.

Apart from a few cordless options, most rotary hammer drills are corded and thus have consistent power and reliability. For projects where a cord is limiting your range, consider a battery-powered tool for backup.

How to Find the Best Rotary Hammer Drills

Hammering and drilling functions are some of the more obvious features, but rotary hammer drills offer a handful of different features for a variety of drilling scenarios. Here we’ll cover what to look for when shopping for this type of drill and what to consider.

Core Bit Sizes and Max Diameters

Rotary hammer drills are for drilling big holes in tough materials, so it makes sense that bit sizes are a priority. Most bits come with a maximum diameter between one and one and a half inches. Despite the potential limitations, no other tool can reasonably be expected to drill holes into concrete and steel, but it’s essential to be realistic about what a rotary hammer drill can tackle.

Bit Types

Bit types for rotary hammer drills are typically either SDS or SDS-Plus, but there are a few other variations as well. If you have never owned a rotary hammer before, expect to purchase all-new bits for the drill (if it doesn’t come with them). It’s unlikely you’ll find an adapter to fit, even if the drill offers multiple modes, such as rotational only.

Some adapter options can help make your existing bits more universal, but cross-checking compatibility is important before you buy.

Depending on the type of project you have in mind, you might also need different bits to drill into various materials and surfaces. Ruining your bits—or worse, your drill—is a potential side effect of not researching the appropriate drill bit for your project.

Drilling Applications

When it comes to shopping for a rotary hammer drill, you should first consider your overall needs. If drilling holes is the only item on your checklist, you can likely choose any of the drills on our list and have a go at your project.

If you want to chisel tile, break up chunks of concrete, drill through rebar, or any other variation of heavy-duty tasks, it’s important to look at the other features in each rotary hammer drill. Even the highest-power drill can stall if you use it beyond the scope of its abilities, so knowing what you need from the start can help you narrow down the options.


All rotary hammer drills are somewhat bulky and heavy, averaging over six pounds. Despite the weight and bulk, you can reasonably expect the drill to have an ergonomic grip which makes it easy to handle. An ergonomic grip is important when holding the hammer drill over your head or in other positions.

Padded handles are a welcome addition, and D-shaped handles help with gripping over long periods. Kickback control, while not a specific ergonomic feature, helps reduce fatigue while you’re drilling and makes using the tool more enjoyable. If going easy on your body is a priority, look for a model with kickback control to ease the vibration and feedback.

Electronic Controls

While technology continues to improve, that doesn’t mean the electronic features on your rotary hammer will be perfect. For many users, torque limiting clutch features, for example, can be frustrating as the tool limits its operation regardless of what the operator wants.

The idea behind the torque limiting clutch feature is to minimize the risk of damaging the motor, even if it’s a bit frustrating for the user. If you’re new to rotary hammer drills, built-in protection is probably a good idea since you won’t know the limits of the tool until you’ve burnt it out.
