The design and shape of cordless power tools makes then fit into areas where corded power tools will not. In many cases, this leads to a sacrifice of turning strength from the motor. Dewalt power tools makes larger voltage cordless power tools to deliver more power for your job. Dewalt cordless power tools are the ones most often selected by professionals. Their dependability and ability to perform heavier work than most of the other lines of cordless tools is the reason for this. When doing repetitive work like hanging sheet rock, drill bits for driving the screws holding the sheet rock in place, tend to wear out and need replacement often. The quick-change heads of Dewalt power tools make this an easy task to accomplish with minimum slowing of the work being performed. Dewalt power tools offers a nice line of cordless screwdrivers and variable speed drills. The power ratings range from 7.2-volt motors up to 24-volt motors delivering the type of power you need. A variable speed drill is used to make a variety of different size holes from very tiny ones used to enable nails and screws to be driven without splitting the wood to large ones used for installing door knob assemblies. When using a variable speed drill, start your drilling slowly to allow the bit time enough to get firmly seated in the hole. This will lessen the chance of the bit jumping when higher speeds are applied which might cause you to drill something you did not want to have drilled. Dewalt power tools offer a full range of both corded and cordless tools. Their durability and easy ability to change accessories makes them highly desired for professionals. Dewalt power tools deliver in work conditions where other power tools fail. The only drawback I can see to this magnificent line of cordless tools is their weight. Having larger voltages to deliver more power means larger battery packs and larger motors as well. If you have to use one of these heavy cordless power tools all day, you will feel like you have done an intensive workout. Because this is a superior product, you can expect to pay a superior price for it as well. While you will see sales for the combo packs available in store ads, you may notice that these are the lighter weight tools. They will perform the work desired in most situation, but for the really heavy duty applications the heavy duty power tools will command a heavy duty price tag. Concrete Cutting: The Unknown Niche Robert Short / Affordable Concrete Cutting 152d What is Concrete Cutting? Concrete cutting is a process of controlled sawing, drilling and removal of concrete performed by skilled operators using special saws that use diamond impregnated blades. Unlike the old- fashioned dusty jack hammer method, modern concrete cutting leaves a smooth attractive finish and utilizes water so as not to create any dust or mess. There are many different kinds of concrete cutting but the most common are wall sawing, core drilling and slab or flat sawing. Wall Sawing is the process of cutting openings such as doors or windows in concrete walls, usually no more than 12 thick but in some cases up to 24 thick. This is accomplished by using a saw that attaches to a track on the wall to be cut. This process utilizes an enormous 30 or even larger diameter diamond blade that can cut 12 or more of concrete all of the way through from one side. This aspect of our business requires the most skill and cannot easily be done by your average do it yourselfer. As stated, wall sawing may entail cutting openings in concrete foundations but may also include lowering a foundation elevation, entire foundation removal and also the cutting of concrete retaining walls in part or in whole. This type of concrete cutting requires skill and experience to cut perfectly smooth plumb and level openings with virtually no dust or mess, so it is a rather expensive service. Most concrete cutting companies charge a minimum of $425 just to take their equipment to a site and cut. Homeowners that build additions on to their home that have basements or cellars commonly find they need to cut into their existing concrete foundation to add an entry or passage between the new and existing basements. It is much easier and in most cases less expensive to have this service performed during the construction process and not after. Core Drilling is the process of drilling perfectly round holes through concrete walls and floors. The diameters of the holes range from 1 to 12 round but average 5 for most homeowner applications. In commercial applications core holes can range anywhere up to 60 round and more. Core holes are used for utility penetrations such as electrical, plumbing and heating but are also commonly used for venting furnaces or clothes dryers. Although not recommended, core drilling can be performed by an advanced do it yourselfer and the equipment necessary to perform core drilling is readily available at your local tool rental and supply store. Most companies have a minimum charge of $250 to core a hole for you and it can take a professional as little as 10 minutes to unload his equipment, core the hole, and reload his equipment. Yet, I have seen homeowners rent the equipment and spend an entire weekend trying to core a single hole and then call a professional to complete the project. Just like with any trade a professional concrete cutter will make his job look easy. Slab sawing, also known as flat sawing, is used to cut horizontal flat concrete surfaces such as floors, bridge decks and pavement. Slab saws feature a diamond blade that is mounted on a walk-behind machine that requires only one operator. They can cut up to 33 inches in depth but generally only 6 or less is necessary in most homeowner applications. Slab sawing is the perfect solution for making penetrations or openings in concrete floors to access and repair a broken water pipe or sewer line. When a basement or cellar is being remodeled to add a bathroom the concrete is removed to add new plumbing for the fixtures. A slab saw is also useful in demolition work to break up and remove a cracked or unwanted patio, driveway or walkway. Sometimes a homeowner might want just part of a patio or other concrete slab cut in order to alter their landscaping. Attempting a slab saw project can be very time consuming for your average do it yourselfer however it can be accomplished. I always recommend spending a few extra bucks and saving yourself some very serious danger and aggravation by contracting a concrete cutting professional. No matter what your project is, don't let a little concrete stand in your way. Concrete can be a homeowner's worst obstacle if he or she doesn't know that there are companies out there that specialize in removing it very quickly and neatly. To find a reputable concrete cutter I recommend that you start with the yellow pages and always check them out with your local Better Business Bureau or your local Department of Consumer Protection.
