Cordless Hammer Rotary Drills Vs Standard Cordless Hammer Drills
One of the most common areas of confusion surrounding cordless rotary units — especially for newbies to the impact drill arena — is how they differ from their close cousins, cordless hammer machines.
Both of these categories share two key features: delivering hammer action in addition to standard rotational drilling, and naturally being powered by a battery pack instead of a mains lead.
The distinction between these groups is the hammering action itself. A traditional hammer unit utilizes a gear-driven clutch to provide the pounding motion — whereas, a rotary hammer drill incorporates two pistons to pummel the target material.
Known as flying and drive pistons, these crucial components knock out greater force than a clutch mechanism can provide — meaning they’re the ultimate masonry drilling and demolition tools.
Do You Need a Rotary Cordless Hammer Drill?
If your projects involve attacking the densest of materials — often in high-level locations or on-site with problematic access to mains power — it’s worth considering a rotary cordless unit.
Providing more impact per inch than a regular hammer drill, these units are excellent at:
- Driving holes in masonry.
- Creating anchor points in concrete footings.
- Pinning cement wall forms.
- Channeling prefabricated concrete for pipes and wiring.
- Preparing bolt holes for HVAC units, guttering, downpipes, to brickwork.
- Light-to-medium demolition.
- Attaching stanchions to masonry.
Cordless Hammer Rotary Drills Safety Precautions
As with any type of drill, you need to follow sensible safety procedures to protect yourself and others.
However, the inherent dangers are exacerbated when using a cordless rotary machine — not just because you’re wielding a high-impact weapon in your hands, but also because of the volatile material you’re addressing.
Brick, cement, concrete, and bonded hardcore contain crystalline silica — often in the form of quartz. Drilling, boring, and chipping away at these materials can release airborne particles of silica — which then become respiratory hazards.
Recent research indicates that mechanically disturbing these particles on construction sites can elevate silica levels to over 280 times the National Institute for Occupational Safety and Health’s (NIOSH) exposure limits.
Breathing in silica dust can lead to:
Hence, it’s crucial when using one of the most powerful cordless rotary hammer drill units that you take necessary precautions, including:
- Wearing a respiratory mask.
- Operating in a well-ventilated area.
- Creating airflow with an electric fan.
- Taking frequent breaks.
- Where possible, working outside.
- Cleaning the operational area frequently — while still wearing your mask.
- Dampening down the surface with water to reduce airborne dust.
How to Choose the Best Cordless Rotary Hammer Drills
However, individual models can vary in particular features that may, or may not, be suitable for the majority of your drilling projects.
Hence, I suggest when seeking your ideal machine, you consider:
Number of Drilling Modes
At the very least, even the most basic rotary cordless tool will have two drilling options — rotation, and rotation with hammer.
Rotation is your back-to-basics, no-nonsense, drilling setting — permitting you to bore holes into woods, metals, and acrylics. Rotation with hammer, as the name suggests, combines this turning action with multiple impacts — making it the ideal selection for creating holes in robust masonry and brickwork.
However, true pro-grade units — such as the 2712-20 Milwaukee cordless rotary hammer drill — boast an extra drilling mode, hammer only.
This makes the tool ideal for pure demolition work — pounding away with no rotation of the drill bit or chisel head. Bear in mind that these three-setting machines are slightly harder on the pocket than their two-mode counterparts — and may be overkill for the average home DIYer.
You may not be particularly interested in the minutiae of the motor workings of your rotary cordless drill — but whether to go brushed or brushless is a valuable consideration.
Brushless motors — due to the lack of, well, brushes — are more efficient than brushed types. With no contact made between the rotor and stator, there’s little loss of energy to heat and friction — meaning that the lifespan of the cordless battery is elevated and you can operate for longer without recharging. The XRH06ZB Makita cordless rotary hammer drill is an excellent example of a brushless tool.
Furthermore, this reduces internal temperatures, which not only increases the longevity of your tool by shielding the unit’s electrical components, but also lowers the heat-in-your-hand — making for a more pleasant drilling experience.
Conversely, brushed motors will use more energy, draining your battery faster. Their only advantage is that they’re more cost-effective to manufacture — meaning a more affordable unit.
Lithium-Ion Cell Type
Typically, the higher the voltage of the power cell, the faster and more torque delivered by the cordless rotary drill. However, this is more of a generalization than a rule — as it can also depend on a brushed or brushless motor and/or internal gearing.
I would suggest of most importance is checking out the mAh rating of the lithium-ion battery — as this determines the length of time you can run the unit from a single charge. At the very least, seek out a tool with a minimum 4.0 mAh — genuine contractor-grade units, such as the Makita XRH04Z, have 5.0 mAh or higher.
Tool Only or Complete Kit
Remember being an excited child at Christmas, unwrapping your present to find your dream toy, and then suffering the heart-wrenching blow as you discover batteries are not included?
Well, you can relive this childhood trauma with your new rotary cordless hammer drill.
Many high-end units are supplied tool-only — that is, with neither a power cell nor charger supplied. While this may not be an issue if you already own a stack of model-compatible batteries — it can be disappointing for newbie cordless users.
Hence, always check whether these two crucial elements, if required, arrive complete with your new tool. The DCH133M2 DeWalt cordless rotary hammer drill comes with a carry case, lithium-ion cell, and a charger in the box.
However, as most cordless hammer rotary drills have an unofficial industry standard of 4000-4800 bpm (blows-per-minute) — differentiation can be challenging.
I would suggest that it’s more useful to check out the force delivered by these blows — measured in foot-pounds (ft-lbs). The higher this rating, the more effectively your tool will power through cement.
All rotary hammer cordless drills include two handles — a molded rear and a removable auxiliary front. These are crucial — otherwise, it would be impossible to adequately and safely control the powerful hammer action.
However, there are two features you should look out for.
Firstly, investigate whether the auxiliary grip is rotatable — and the extent of this rotation. Some units facilitate full 360-degree positioning, allowing you to tailor the handle to suit your drilling style, angle of address, and demands of your base material.
Secondly, examine whether the rear molded handle has a D-design. Although not crucial for all users, it does allow for elevated grip and pushing force — necessary if your projects involve tackling the densest of masonry. The best rotary hammer drill for concrete — the Makita XRH04Z — possesses this feature.
Hammer drilling with a monster rotary cordless machine can be tough on the digits, hands, and arms.
Repetitive pounding — especially over extended periods — can induce aches, pains, and fatigue. In extreme cases, this constant oscillation can cause permanent damage to the nervous and vascular systems.
I therefore seriously suggest that you look for a machine that has both vibration-absorbing casing and handles — for example, the Makita XRH05Z — shielding you from harm and delivering a more pleasing drilling experience.
A common feature among cordless drills, including rotary examples, is the inclusion of an in-built LED lamp.
While not crucial for many masonry applications, it can be a bonus if you’re operating in dimly lit locations such as beneath floors, in attics, or inside basements.
Permitting run times of up to 45 minutes from a single charge, high-impact rates, and an unmatchable pounding grunt delivered by twin pistons — these extreme tools are ideal for masonry, brickwork, and concrete applications.
As suitable for serious DIYers as they are for trade pros, these machines are the ultimate portable drills for dense materials. Always investigate whether your chosen tool arrives with a battery and charger to prevent later disappointment — and that it boasts a vibration-busting build to enhance your drilling experience.
Sure, for general household timber, metal, and plastic projects — they’re complete overkill. But, if your jobs involve tackling the most hardcore of materials — get yourself one of the best cordless rotary hammer drills.
