No matter what kind of job you are tackling, having a good drill bit can make any drilling job easier. As far as construction goes, the angle of the point and the material it's made of determine what you use it for. If you are drilling through hard metal, look for a titanium-coated or cobalt drill bit that has a flatter point. Split-point tips and sharper points are more accurate and work better with softer metals like aluminum.

Different materials (and projects) will require different drill bits, so it's important to do your research before you buy. To help you find the right option for your next home renovation or DIY project, here are the top-rated drill bits on the market.

    Best Overall: Irwin Tools 3018002 Cobalt M-35 Metal Index Drill Bit Set

    This set earns the best overall spot because of the wide range of drill bits included and their versatility. Whether you're an experienced handyman or a beginner, you will be able to appreciate a kit that gives you everything you need and more. Irwin packed this kit with 29 drill bits made with heavy duty web construction and cobalt steel. This gives the bits strength and extends the life of the sharp cutting edges. The kit contains 29 bits ranging from a 1/16-inch to a ½ inch bit in 1/64-inch increments. The reduced shank allows for a larger drill bit to be used in a standard 3/8-inch chuck. Reviewers, particularly those new to using drill bits, liked the tap and drill selection chart as well as the rubber over mold case. The sturdy case kept the wide-range of bits from falling out or twisting around inside of the kit when in transit.

    Drill America has made a high speed shank drill bit that slips effortlessly through stainless steel to create perfect holes without leaving behind a path of grit or rough sides. The wear-resistant round shape of the shank has three sides with flat ends that create a good grip when they come in contact with the chuck. The spiral flute at the end of the bit pulls bits of the material being drilled away from the work surface so it won’t clog the job. The surface of the drill bit is treated with abrasion-resistant black oxide for a long-lasting tool accessory. Aside from stainless steel, it can also be used for iron and bronze projects. Reviewers say that for serious jobs, this tiny workhorse performs well and produces professional results.

They are ideal for a number of jobs in a wide-range of industries, from drilling out broken bolts, adjusting manifolds, removing exhaust systems to fixing or installing car engine parts.

    Best Titanium Set: Bosch Tl18 18-Piece Titanium Twist

    It is a durable coating that extends the life of the bit and bores through material faster than its counterparts, which is why titanium is one of the more popular materials on the drill bit market. The Bosch Tl18 18-piece titanium twist kit has a plethora of pieces to get through wood, sheet metal, plastic, Plexiglass, vinyl siding and is strong enough to cleanly bore through cast iron surfaces. Each drill bit is coated in titanium nitride. Bosch’s speed helix design gets the right bit through the correct material faster than other drill bits, according to reviewers. The titanium bits last six times longer than high-speed steel and have a balanced double flute that significantly cuts down on vibration. This will save time, muscle fatigue and increase the lifespan of the drill battery on projects.
