Corded vs. Cordless Drills

When selecting an electric drill the decision between a corded and cordless model may seem like a no-brainer to some – <em>why have a cord when I can enjoy the freedom of a cordless drill?</em> Well, if it were that easy there wouldn’t even be a choice. It’d be cordless drills for all! But, since corded drills are still an option then there must be something that sets them apart from their cordless cousins, right? Right. So, what’s the difference between corded and cordless drills, and how will that impact your drill-buying adventure? We can break it down into three main areas: <em>weight</em>, <em>power</em> and <em>performance</em>. <strong>Drill Weight</strong> Generally speaking, a cordless drill is going to be heavier than a corded model of comparable performance because its battery will add a couple more pounds to the overall weight. For example, <a title="DeWalt Power Tools" href="http://www.atgstores.com/dewalt_m8557.html" target="_blank">DeWalt’s</a> DCD940KX XRP cordless drill weighs in at 6.25 pounds, whereas the DW222 corded model sits at an airy 3.3 pounds. Ah, but what about said power and performance, you may ask? That’s a good question and we’ll use these two models to illustrate those differences now. <strong>Drill Power</strong> Drill power may often refer to amps or volts, but since these are not easily relatable it’s better to look at output as measured in <em>watts </em>or <em>rpms (revolutions per minute)</em>. Using our previous examples, <a title="DeWalt DCD940KX XRP cordless drill" href="http://www.atgstores.com/cordless-drills/dewalt-dcd940kx-xrp-cordless-drilldriver-kit_g850977.html?isku=7023775&amp;linkloc=cataLogProductItemsImage" target="_blank">the XRP cordless drill</a> delivers a max output of 450 watts at a variable speed of up to 2,000 rpms. Not bad for a battery-powered drill. <a title="DeWalt DW222 Heavy Duty VSR Electric Drill" href="http://www.atgstores.com/corded-drills/dewalt-dw222-heavy-duty-vsr-electric-drill_g850969.html?isku=7023767&amp;linkloc=cataLogProductItemsImage" target="_blank">The DW222</a>, on the other hand, puts out a max of 520 watts at a speed up to 1,200 rpms. Why more watts? Well, because the corded drill is drawing continuous power from a 120-volt socket while the cordless model is working from an 18-volt battery that starts losing power the moment you flick it on. But, wait! There's more ... <strong>Drill Performance</strong> The fact that a cordless drill like the DW222 can create that much output from a battery is impressive, but it’ll eventually run out of juice. But, check this out – the cordless drill in this comparison delivers<em> higher max rpms in three different settings</em>. Very nice! Even so, you have to remember you'll be enjoying that additional zip at an increased cost in terms of dollars spent <em>and</em> tool weight. Naturally, various drill features and options will also impact performance, but the other major difference between the two is the cord itself – or lack thereof. Cords can limit both mobility (where you use it) and maneuverability (how you use it) and that’s something you also have to consider. Finally, keep in mind that these are just two options out of many and factors vary between drills and drill brands. Even so, this information should give you an idea of what will work best for you. <a title="ATG Stores Homepage" href="http://www.atgstores.com/" target="_blank">ATGStores.com</a> hopes this comparison helps you when making your next drill purchase and welcomes you to comment on other factors that might influence your choice.
