Which Drill-Driver Makes The Ideal Gift For The Diy Enthusiast?
If your DIY requirements do not stretch beyond hanging a few picture frames, chances are all you’ll ever need is a budget priced basic 14Volt DIYer Drill-Driver, many which require up to 3 hours or more to recharge the batteries. But if like many who enjoy DIY and are interested in taking on more ambitious tasks, chances are you’ll be in the market for a more sophisticated Drill-Driver.
On the otherhand if the DIY requirements are more demanding then there are two essential to consider when selecting a cordless Drill Driver and they are Torque and Battery power.
Torque which is the measure of rotational power or force applied by the power tool to drive or rotate the screw. The greater the torque available, the easier the screw will turn. A clutch is used by Drill-drivers to control torque. Ideally, the more torque settings (amount of torque applied) the better the performance required to sufficiently turn the screw and to stop turning when the screw head is tight and snug. Ability to adjust torque is critical, not only to avoid damage to screw head by applying too much torque but to be efficient when the project involves working with many screws. Look for models with more torque settings, so chances are a model boasting 25 settings is probably more versatile than a model with 16 settings.
For cordless power tools, Lithium-ion (L-ion) battery power tools are much more efficient battery technology than the traditional Nickel-cadium (NiCd) or Nickel-metal hydride (NiMH) battery cells. L-ion batteries deliver not only more current which means more power but also retain power charge for longer time, which is why all the latest 18v power tools feature L-ion batteries. Another important feature of L-ion batteries is that unlike the traditional batteries which suffer ‘memory effect’ (when a battery capacity is reduced by repeated top-up charging) L-ion batteries do not suffer ‘memory effect’.
The enormous success of Drill-Drivers is due mainly to their popularity as a powered screwdriver. Unlike the fast turning electric drill bit, you have a slow turning screw driver, which can generate more rotational force (torque). Usually a slide switch can reverse the spin direction which is required for removing screws.
Latest trends in Drill-Driver product design sees the emergence of a more sci-fi styling featuring a more compact size and less weight. But don’t be fooled by the outward size and appearance, these tools are well capable of meeting the demands of serious amateurs as well as professionals. Product performance typically includes 1200rpm, and 22 clutch setting positions, high and low ratios, LED work light and touch sensitive triggers allowing fine control and generating a massive 25lb of torque and more clutch, Battery recharging time has been dramatically reduced to 30 minutes or less. Market leading models are powered by 18V lithium-ion batteries.
