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.

    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.

    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.
