Rockwell’s new 12-volt H3 is a cordless rotary hammer drill with an SDS Plus quick chuck. Somehow, Rockwell managed to pack quite a bit of power into a compact and lightweight tool.

The drill’s 3-in-1 quick change chuck can be used to equip the tool as a rotary hammer drill, conventional 3-jaw drill, or power screwdriver.

Specifications

Rotary hammer impact rate: 0-4800 BPM
Drilling mode: no-load speed 0-900 RPM
Dial switch for switching hammer mode on and off (looks like it would be easy to toggle with gloves on)
Drilling capacity: 3/8″ in wood and concrete, 5/16″ in steel
Runtime: up to 15 1/4″ holes in 4800 psi concrete per charge
Charging time: 75% in 15 minutes, 100% in 30 minutes

Rockwell’s LithiumTech 12V charger also features a built-in USB recharging port for charging compatible devices.

While 15 1/4″ holes doesn’t seem like a lot of holes per charge, we think it’s actually rather impressive given the tool’s size. As far as we are aware, there is only one other 12V cordless rotary hammer on the market, a heavier duty Panasonic model.

The H3 12V 3-function hammer drill (#Rk2513K2) is expected to be priced at $180, and is due to hit the shelves at local retailers and hardware stores this spring along with the new cordless SoniCrafter.

Festools offers two main types of drills, one with a “D” handle and the other with a traditional drill handle. The Festool drill is a little different than other types of professional power tool drills. One of the biggest differences is they use a “Brushless” motor. According to Festools, this drill will last longer because you have fewer items to wear out. Another nice feature of the”brushless” motor, is efficiency. This means you can do more work without hitting the charger as often.

Festool drills have a Fastfix chuck system. The Fastfix system is basically their quick lock system so the shank is locked in and you don’t have to tighten a chuck. This drill comes with a variety of accessories, so in essence it can be a 5 in 1 drill.

These drills have a lower over all design which makes them slim. This lets the user get into tighter spaces. As you can see by the picture, you don’t have the traditional bulky battery.

If you only need a hammer drill occasionally, perhaps you could get by with this Mastercraft hammer drill adapter. After chucking the adapter into your drill, you activate the hammering action by holding onto the adapter while you operate the drill.

The adapter requires a drill with at least a 3/8″ chuck. If you want to use the adapter with a cordless drill it should probably be a 12V or higher model. Canadian Tire retails this hammer drill adapter for $25. And for some reason, Duluth Trading Company charges $35 for their seemingly identical version.
