Do you have an eye for industrial-strength drill bits with the capability of drilling smooth holes of identical sizes?
Then look no further than the Black & Decker 15557. The sizes of the drill bits have a drilling range of between 1/16-inch and 1/4-inch and can work perfectly well when paired with a hammer drill with a 3/8-inch chuck. These drill bits are perfect for penetrating through different rugged materials around the home with utmost ease. As a result, you can use it on plastic, wood, and steel. Since they start drilling the very moment they come into contact with drilling material, you will end up with smoother and cleaner holes.

The ten drill bits in this set are more than enough to enable you to complete a wide range of masonry and steel drilling projects. Low-quality drill bits have a tendency of heating up to unbearably high temperatures following hours of use. This is not the case with Black & Decker 15557 drill bits. The construction of the drill bits is aimed at making them quite resistant to both heat and abrasion. Additionally, you will be using the drill bits for several years since the industrial-grade steel used on the cutting allows for the re-sharpening of the cutting edge.
Keeping in mind that the Black & Decker 15557 drill bit set is basic, it should not be used for heavy-duty industrial applications. We highly recommend that before using these drill sets, make a point of properly lubricating all the bits with a lubricating agent so as to get more out of them. If you want to drill a large hole, it may be necessary, to begin with, a small one before proceeding accordingly.
In all, the drill bits of the Black & Decker 15557 are sure to last a lifetime with proper use of recommended materials, drilling into wood and other densely composed materials with exceptional performance. For purposes of convenience, the drill bits set comes with a plastic drill bit holder, so you can transport bits around your workstation with relative ease.

Criteria for Evaluation
When choosing the options in our top 10, we made sure to follow some strict quality criteria. We suggest you use the same criteria for your own search before making a purchase.
Construction Material
Drill bits come in several metal variations, and their suitability for working with particular materials also differ significantly. In case you are intending to use the drill bits to bore through metal, pay particular attention to available robust varieties capable of delivering superior performance. Abrasive materials such as aluminium and stainless steel, for instance, will necessitate the use of industrial-strength drill bits that do not whether quickly.
Design of Drill Bits
Having decided on your preferred construction material, the subsequent step is looking at the most suitably designed drill bits. Other than differences in design, there are also differences in boring angles, and your choice should be informed by the materials you intend to drill. A step-design is more appropriate for drilling through hard metals compared to twist designs.
Durability
Drilling is a tough job, and in cases involving hardened metals, there is a high likelihood of generating high temperatures and corroding the cutting edge of the drill bits. As a result, it is important that your choice takes these two factors into consideration when searching for drill bits. Time and again, titanium and cobalt have been praised highly for their ability to resist heat and abrasion.
Re-sharpening
As already mentioned, drilling through hardened materials generates heat and friction, which, with increased use, reduces the cutting edge of the drill bits. Since titanium is an industrial-strength material, sharpening it is exceedingly difficult. Cobalt, on the other hand, is easy to re-sharpen. Since titanium coating guarantees you a longer shelf-life, sharpening it may negate this advantage.
Type of Coating
Drill bits have sharp tips that various manufacturers make a point of coating so as to enhance their versatility and performance. The two most common types of coats used are the black oxide and titanium oxide or nitride. While the former is effective at strengthening the tips, it is unsuitable for non-ferrous metals. The latter, on the other hand, increases the capability of drill bits to bore through abrasive materials by increasing their resistance to corrosion and strength.
FAQs
Q: What are drill bits?
A: Drill bits are the apparatus professional contractors, and DIYers use to bore holes through the surface of different materials such as wood, PVC pipes, metals, and plastics. They vary greatly in design and size. While those with twist designs are more suited to drill through metals, plastic, and wood, the ones with step design easily drill through abrasive materials.
Q: What types of materials are used to make the drill bits?
A: Drill bits are made from numerous materials offering different degrees of resistance to wear-and-tear, strength, and cutting edge. The harder the material used to make a drill bit, the more expensive it will be. The various types of materials used to make drill bits, in ascending order of hardness, are carbon steel, high-speed steel, cobalt steel, titanium-coated, and lastly carbide. The main difference between titanium-coated drill bits and carbide drill bits is that the latter drills through stainless metal and other hardened materials with a lot of ease.
Q: How do I stay safe while drilling?
A: When paired with hammer drills, drill bits rotate at exceedingly high speeds and in the process of drilling, especially through metal, produce a lot of drilling debris that could get into your eyes. Given the proximity of your face to the flying shards and splinters, it is a good to protect your eyes by wearing eye protecting goggles. Heavy-duty projects will automatically necessitate the use of gloves and ear buds in addition to the goggles. As much as possible, have an extra pair of hands in the workstation to help with handling heavier drilling materials. C-clamps are of great help with securing smaller applications together before drilling.
Conclusion
Drill bits today are considered a necessity in the workstations of professional contractors and at home. They are a must-have tool for those who regularly perform repairs and improvements around the house. We based our selection of the ten best drill bits on the material used to make drill bits, design, longevity, the possibility of re-sharpen, and the type of coating. In our analysis, the clear winner is the DeWalt DW1263 14-Piece Cobalt Pilot Point Drill. The drill bit set adequately addresses all your drilling needs and is perfect for tackling a multitude of applications without stress. The superior quality drill bits are neatly arranged in a convenient carrying case for easy transportation.
