Finding The Best Cordless Drill

Hitachi DS18DSAL

In recent years, cordless drills have become more and more popular. They certainly shine when it comes to light-duty operations. Since battery powered units do not require an external power outlet, they can go anywhere. Do not expect a cordless drilling tool.to do things that are reserved for corded models. But in certain situations, cordless drills are the preferred choice of the do-it-yourselfers since they offer complete freedom of movement.

On the market, there are numerous makes and models to choose from. Other than battery, there are other factors that determine the price of a cordless drill such as the power of its motor, the number of features offered and the accessories included. You need to carefully identify what you plan to do with the drill before making a purchase.

Speaking about batteries, basically there are three major battery types, NiCD (Nickel cadmium), NiMH (Nickel metal hydride) and Li-Ion (Lithium ion). Each has its pros and cons. They typically range from 12 to 18 volts. Just keep in mind that not all batteries are created equal. They offer different run time, life cycle, volts and amp-hour rating. While battery operated tools come with some limitations, newer models have larger capacity batteries with longer lifetimes and faster charging systems.

The DeWalt DC970K-2, for instance, is powered by 18V NiCAD battery. The battery charge time is 60 minute. Two batteries are included in the package. No need to worry about running out of battery. The Black & Decker LDX220SBFC is a 20-Volt Lithium-Ion drill/driver. The newest battery technology allows 35-minute rapid charging rate.

When comparing two models, it is important to look beyond the voltage. Even though they provide the same voltage, one of them may offer a higher mAh rating. A higher rating generally means a longer run time. This applies as long as both models use the same battery type.

When it comes to torque power, generally the higher the voltage level, the higher the torque rating. However, two units featuring the same voltage do not necessarily provide the same amount of torque. Both the Black & Decker LDX120C and the LDX220SBFC are a 20 volts Lithium-Ion powered model. But the Black & Decker LDX120C offers 115 in-lbs maximum torque while the LDX220SBFC claims to deliver 310 in-lbs.

Many cordless drills today are equipped with a reversible, dual-speed motor and a trigger with variable speed, enabling users to perform a wide range of screwdriving and drilling works. The DeWalt DCD760KL, for instance, offers 0-500/0-1700 rpm.

Battery powered units usually use a 3/8″ chuck to hold the bits. If you need to drill a bigger hole, choose the one with 1/2 chuck. But for around the home, 3/8″ is fine. Drill chucks can be keyed or keyless. Older models require the use of a key to insert or remove the bit into the chuck. Keyless chuck system allows easier switching of drill bits.

You can find units that include nice features and extras such as built-in LED light or carrying case. In addition to a carrying bag, the Black & Decker LDX120PK also includes 66 hand tools and accessories such as spade bits, metal drill bits and needle nose plier.

Different Types of Hand Held Electric Drills For Your Projects

Choosing the right tool for the job at hand is a key to obtaining desired results. When it comes to hand held electric drill, different makes and models are available in the market that choosing the best one can be a daunting task. However, portable power drills generally can be categorized in a number of types.

Regular Drill

For a novice DIY user, a basic hand held drill should meet the requirements. Many are priced under $50 and do not come with advanced features. The most basic ones operate at a fixed, single speed. Offering compact size for comfort and control, they are designed for light maintenance and repair.

As for the chuck size, the maximum capacity is usually 3/8 inches. For more power and more versatility, pick a half-inch drill that will handle most typical bits. The Black & Decker 7152, for instance, use a 3/8″ chuck. As a basic model, it only offers single speed for general purpose drilling. But the 1200 RPM corded rill has a reversibility option.

If you are willing to spend more, choose the one which can run from zero to a pre-set limit in forward and reverse direction. VSR drill will allow the user to easily start holes and drive screws. The trigger-controlled variable speed feature allows for better control. The DeWalt DWD112 is a good example of VSR pistol grip drill.

A number of variable speed drill/drivers have two or more speeds ranges. This allows you to easily match the correct speed to the job. The DeWalt DC970K-2 provides an RPM of 0-450 and an RPM of 0-1,500 that allows for a wide range of drilling and driving applications.

Hammer Dril

While regular electric drills are invaluable tools for small projects around the house, they are not suitable for drilling through harder materials. For strenuous jobs such as concrete or masonry drilling, you should use a hammer drill. With the combination of concurrent hammering action and rotating movement, it can drill holes in masonry or brick much better and faster than a regular one.

The hammering motion of a hammer drill is usually measured in BPM (blows per minute). This indicates the maximum speed of the motion. Nowadays, there are cordless units that are relatively light in weight. Powere by 18-Volt Lithium-Ion, the Bosch HDH181-01 is just under 5 pounds. This hammer drill/driver boasts 700 in-lbs of torque and produces 27,000 BPM at no load.

Rotary Hammer

Similar to standard hammer drills, rotary hammers also combine rotation with an in-and-out hammering motion to make penetrating hard, brittle surfaces possible.. The difference is in order to provide the hammer action, rotary hammers use a piston mechanism. This allows them to
deliver more powerful hammering action than typical hammer drills. If your projects involve drilling through aged concrete or other tough materials, then a rotary hammer is you what you need.

The 11255VSR from Bosch is an example of a corded rotary hammer that would be suitable for homeowners. This model offers three modes of operation that allows for greater versatility: rotary hammer, hammer-only and rotation-only mode. The tool features SDS bit retention to withstand the hammering motion.

Right Angle Drill

When dealing with tight spaces, a right angle drill is the only tool to use. The chuck is positioned at a right angle to the main drill housing. This special type of drill is designed to tackle jobs where other drills cannot such as drilling between studs and joists. The characteristics of right angle drill make it an ideal tool for plumbers and electricians.

When you are shopping for an angle drill, expect to spend at least $100. Like standard drills, they also come with different styles and features. The Makita DA3010F is one of the popular models. Fitted with a white LED light, it offers a compact, lightweight design for perfect working in tight areas.

By selecting the right hand held power drill, you would be able to accomplish your projects easier and faster. Using the wrong one, you could end up making costly mistakes. Once you have decided the right type for the job, spend some time reviewing some products availabe in the same category.
