"  A cordless drill is indispensable. It drills holes, drives and removes screws, and can do a variety of oddball jobs such as stirring paint. But without the right accessories, it will never live up to its full potential. The Essentials Protect your eyes when drilling holes, especially when drilling into steel. Since you&amp;#039;re more likely to wear safety glasses if they&amp;#039;re comfortable, we suggest a model like 3M&amp;#039;s new Tekk glasses, complete with anti-fog coating. Next up: drill bits. Until you start tackling complex projects, your best bet is a set of general-purpose twist drills with a 135-degree split point. These will drill mild steel, wood, and plastics, and will help you make small holes in walls, floors, and ceilings. A simple 15- or 18-piece set, like this one from Irwin, is enough to get you started. You can always buy larger, longer, or specialized bits later.  To ensure you don&amp;#039;t drill any farther than you want or need to, you can mark the shaft of the drill bit with masking tape. But a more precise method is to use a drill stop. If you spend much time driving fasteners, you&amp;#039;ll also need a kit of replaceable drive bits. A basic set in a clamshell case provides enough versatility for maintenance, repair, and small construction projects. Insert the drive bit in an extension for extra reach. The Supplies The first thing you need is information. The L.S. Starrett Company, a manufacturer of precision hand tools, makes its literature available via free PDFs. Its famous Tools &amp;amp;amp; Rules booklet is an excellent guide for matching drill size to an appropriate tap if you&amp;#039;re making threaded holes for bolts and screws. Now that you&amp;#039;ve read up on boring holes (sorry), you&amp;#039;ll need the supplies to actually do the work.  To prevent your drill bit from spinning away from where you want to drill (a problem called &amp;quot;walking&amp;quot;), you may need to mark an indent using a center punch. This is particularly true of drilling steel. Buy a center punch and strike it with a ball-peen hammer. For even more help to get the hole straight through a flat or curved surface, get a V block gauge. Don&amp;#039;t forget to use cutting fluid to lubricate the bit when boring in steel; it&amp;#039;ll make the hole easier to drill and keep your bits sharp longer. We&amp;#039;ve used Relton&amp;#039;s Rapid Tap for years and swear by the stuff. As your drill bits wear down and it&amp;#039;s time to buy replacements for your set, you may find the size is difficult to read on those old bits. A fractional drill bit gauge helps you be sure you&amp;#039;ve got the right drill for the job. Finally, expanding your selection of bits will help you get the most out of your drill. A basic set of spade bits will suffice for all but the most specialized jobs. For really big holes, use a hole saw. Bi-metal types last longer and can handle drilling in tough, abrasive materials like drywall and particle board. And for tiny holes, use this Rockler Micro Drill Chuck. The Extras Probably the most useful extra for your cordless drill is a pocket hole drilling system. This allows you to quickly and neatly join two pieces of wood while making furniture, a cabinet, a workbench, or other great projects. If you&amp;#039;re an avid woodworker, you&amp;#039;ll also want countersinking drill bits, which you can buy individually or in sets. These not only make it easier and neater to install countersunk screws, they also make it much easier to drill a hole for setting hinges. A drill bit sharpener reconditions your drill bits so you don&amp;#039;t always have to buy new ones. And drill bits aren&amp;#039;t the only things that need sharpening: If that desktop pencil sharpener just isn&amp;#039;t enough for you, try this power-drill pencil sharpener that will ensure your carpenter pencil always has a fine point.
