Is a cordless rotary hammer rill worth the cost? While the initial outlay can be double or even triple what you are paying for a corded tool, consider a few facts that will help you decide if they are worth the spend.
Convenience. While we don’t often think of the convenience factor when looking at a power tool, really that is what it is all about with cordless tools. A cordless rotary hammer drill is always at the ready (assuming you keep your batteries charged!). You won’t be spending time looking for your power, running a cord and then rolling the cord back up. Open the case and drill, put the tool back in the case, easy.
Power. There was a time when cordless rotary hammer drills were only considered for use in lightweight applications like 3/16” holes. Today’s tools are incredibly powerful rivaling corded tools of the same capacity. For instance the new Bosch GBH18V-26K24 will out work many corded hammers. When you pull the trigger, you can just feel the power. Most of these tools are now rated for thin wall core bits as well, making them even more useful.
Run Time. New battery technology is the driving force behind the increase in usefulness of all cordless tools. Most cordless hammers are packed with 2 battery packs and most of the batteries included have increased mah capacity. Remember in the world of batteries, all things being equal, mah represents your gas tank or run time, more mah, more run time. If you have stayed away from a cordless rotary hammer because of run time, trust me you won’t be disappointed.
Cord Cost. One hidden cost to consider on any cordless tool is extension cord cost. A good quality extension cord can be very expensive and they can have a short life span on the site with all the traffic. Cords are a common theft item on the site as well. And did you know, using long extension cords can actually damage your corded tool?
Safety. Safety, safety, safety! More and more time is being spent on job site safety and a lot of focus is being put on concrete dust, including that resulting from hammer drilling concrete. Here is where a cordless rotary hammer drill can really shine. Many of the current tools can be purchased as a fully self -contained dustless unit with the vacuum on board. Not only can you purchase a dustless rotary hammer cheaper than buying a corded hammer and separate vacuum, consider the space needed in your truck, each truck to haul the unit. Add to that dragging it around a busy site, tripping over the cords or working on a ladder, a cordless rotary hammer drill is a no brainer.
Warranty. Most power tools have a 1 year warranty. But did you know that most cordless tools have a better warranty, some between 3-5 years? Many of these warranties require you to register your tool, but that is really a small price to pay for such an excellent warranty.
Consider the points above when you are looking to add a hammer drill. I think you will find some real benefits from purchasing a cordless rotary hammer drill.
