A cordless rotary hammer offers many benefits over a corded tool. While a corded rotary hammer can run all day without changing batteries and can handle some larger bits, the cordless SDS drill is becoming the tool of choice, especially with newer battery technology.

You can find a cordless SDS drill offered by most of the major tool manufacturers. Your tool options start with a lightweight 14-volt Panasonic at just 5.1 pounds to the amazing 36-volt Bosch 11536VSR unit, my personal favorite. So what is the right tool for you? That answer is best determined by your request.

If you primarily drill smaller holes for tapcon and small anchors, 5/32 “-1/4” any of the offered cordless SDS drill kits will do this with ease. Usually when you are drilling smaller holes, you are drilling more holes, so a lighter unit may be better for you.

If drilling larger holes, up to 1-1 / 4 “(the largest solid SDS bit available right now) is common, you will definitely want one of the 36 volt tools. Some of these tools also display a rating for a slim bit. of wall core that will allow you to tackle larger holes, such as 2 “. These types of tools are popular with electricians who need to run emt through block and concrete walls. These holes are typically 12 “deep and it takes energy to push these bits through.

Another feature that has become more common in cordless SDS drilling tools is the ability to disable hammer action to drill into other materials. You will need a straight chuck adapter SDS. More and more tools offer this plus the ability to turn off the rotation. Add a chisel and you now have a cordless chipping hammer, perfect for light applications.

SDS cordless drilling tools are gaining traction, especially with new battery technology. Some of these tools are competing with their wired brethren for power and simply destroying them for convenience. So the next time you need a rotary hammer, consider a cordless SDS drill and throw in your extension cord.
