With so many different types of drills and drivers available today, it is understandable why
you need more information about which is the right tool for a particular job. Hammer drills combine the rotation of a conventional driver with the force of a hammer to drive the bit into tough surfaces like concrete, brick or block, making it ideal for many types of projects. As you go about thinking on which hammer drill to buy, there are a few points you will want to consider.
>> Which type of hammer drill is best for you?
Selecting the best hammer drill from the many options available requires that you first consider where and how you will be using the tool. As with other power tools, the primary categories to choose from are corded and cordless.
• Electric -Electric or corded models offer more power and will work anywhere there is outlet. These types of hammer drills are a great choice for most home improvement projects because they can be used anywhere you need more power than you can get from a cordless drill.
• Cordless -In the world of portable power tools, a cordless hammer drill is quite valuable. A cordless hammer drill uses a battery that is designed to deliver enough power to operate the tool far from outlets, freeing you to get the tough jobs that are beyond the reach of corded drills.
>> Consider hammer drill uses
The decision about how to buy a hammer drill is the same as buying other power tool sets. A hammer drill comparison will reveal that they come in different sizes and of varying power. The diversity of choices is a reflection of the many hammer drill uses, and you will want to find a hammer drill that is designed to work with the materials you are going to use.
• Brick -Brick construction has been around for thousands of years and the need to make holes in brick has been around just as long. Interior walls with exposed brick are a very popular architectural feature that requires specialized power to accomplish everyday tasks such as hanging a picture.
• Block -All types of concrete block, including cinder-block and paving blocks, occasionally need to be drilled into in order to attach things such as outdoor lighting or mounting brackets for yard accessories. All major hammer drill brands will be able to accomplish these tasks.
• Concrete -Concrete is used to bind brick, block and pavers to each other, and on its own to form walkways and patios. If you need to punch holes in concrete, you'll want a hammer drill that's powerful enough for the task.
• Chiseling -Having the right power tool accessories and gear is vital to being able to complete specialized jobs, such as trimming concrete or brick. If chiseling is one of the needs you anticipate, consider hammer drills that accept chisel blades.
>> Consider features
One of the most important lessons in learning how to buy a hammer drill is understanding what the different features are so that you will be able to determine which ones matter most to you.
• Motor -There are two types of motors available, and the type you choose can have a dramatic effect on the performance of your tool. Some hammer drill brands offer brushless motors for cordless models. By replacing carbon brushes with a microprocessor, efficiency is improved and battery life is extended.
• Transmission -The transmission of your tool operates in a similar way to the transmission of your car. It converts the power from the engine into torque. The best hammer drills feature multi-speed transmissions. This feature helps deliver the right amount of power for different types of projects.
• Mode switch -There are some types of hammer drills that are able to function as two drills in one: a rotary drill and a hammer drill. A mode switch allows you to quickly and easily switch from hammer to rotary mode and back again.
• Chuck -The part of a drill that opens and closes to hold a bit is called a chuck. The range of sizes that a chuck can be opened generally runs from 6 to 20 millimeters, depending on the hammer drill size. Be sure that the chuck can accommodate the bits you want to use.
• Side handle -One of the more useful features when deciding how to buy a hammer drill is a side handle. A side handle sticks out from the side of the tool and enables you to apply forward pressure to the drill in order to get through hard materials like concrete.
• Depth stop -When drilling into a material, it is often very important to know just how far in you are going. A depth stop is a device that protrudes to a specific distance behind the tip of the drill bit. When the bit penetrates to the required depth the depth stop prevents the drill from going further.
>> Consider drill bits types
When shopping for home improvement supplies to accompany your new tool, the one essential item is a diverse supply of drill bits. There are different types of bits to do different jobs. Be sure that the bits you want are compatible with the hammer drill you are looking at.
• Masonry: Masonry bits are usually tungsten-carbide tipped and are specially designed to penetrate bricks and concrete.
• Diamond: This is a very specialized drill bit that is built to penetrate the hardest of materials, including masonry. These bits function best at slow speeds.
• Multi-purpose: These bits can be used in all types of hammer drills and are the most versatile available. They will cut through materials from plastic to wood, metal and masonry.
• Titanium nitride: They are designed to reduce heat build-up and therefore increase their useful life.
• Cobalt: Drilling through extra hard material builds up a lot of heat, and these bits are resistant to high temperatures.
Lastly, be sure to research any and all individual hammer drills you are considering buying. Read up on user and expert reviews. This way, you'll be able to find the best hammer drill to buy to meet your particular needs.
